[0001] Cross-referencing of related applications
[0002] This application claims priority to Chinese patent application CN202510141860.5, filed on February 8, 2025, the entire contents of which are incorporated herein by reference.
[0003] [Technical Field]
[0004] This application relates to the technical field of metal welding, and in particular to a composite welding apparatus and a control method for the composite welding apparatus.
[0005] [Background Technology]
[0006] With the development of technology, welding technology is required to join workpieces in fields such as machinery manufacturing. Metal welding plays a crucial role in this process, which is a manufacturing or sculpting process for joining metals. During welding, the workpiece and the solder may melt or not, forming a direct weld seam. Pressure is usually applied to join the workpieces. To improve welding results, electrode welding and laser welding are often used in conjunction with welding the workpiece.
[0007] However, when electrode welding and laser welding are combined, the molten weld from electrode welding splashes onto the laser lens, contaminating it and reducing laser transmission efficiency, which in turn leads to a decrease in weld quality. Furthermore, laser welding stirs the molten pool, causing shielding gas disturbances and arc fluctuations in electrode welding. It also heats the welding wire, altering its melting characteristics and affecting the welding stability of electrode welding. This, in turn, increases welding spatter, leading to a decrease in the laser power emitted by laser welding. Ultimately, this affects the welding effect on the workpiece.
[0008] [Summary of the Invention]
[0009] This application provides a composite welding device to solve the problem of mutual interference when electrode welding and laser welding are combined.
[0010] To address the aforementioned technical problems, this application provides a composite welding device, comprising: an electrode welding assembly and a laser welding assembly, wherein the laser welding assembly and the electrode welding assembly are correspondingly arranged and coupled; wherein the electrode welding assembly and the laser welding assembly are arranged corresponding to the same welding component, and the electrode welding assembly and the laser welding assembly communicate through a synchronization signal so that at the same time, one of the electrode welding assembly and the laser welding assembly outputs normal energy, while the other outputs low energy or does not work.
[0011] The electrode welding assembly includes a first control component and a welding wire fixing component. The welding wire fixing component is coupled to the first control component and is used to fix the welding wire. One end of the welding wire corresponds to the welding point of the laser welding assembly.
[0012] Among them, the welding wire fixing component is a movable part, which drives the welding wire to reciprocate under the control of the first control component, thereby driving the welding wire to approach or move away from the welding point of the laser welding assembly.
[0013] The laser welding assembly includes a second control component and a laser emitter. The second control component communicates with the first control component via a synchronization signal. The second control component is coupled to the laser emitter, and the axial direction of the laser emitter is set at a preset angle to the axial direction of the welding wire.
[0014] The composite device also includes a power setting module, which is coupled to the electrode welding assembly and the laser welding assembly, and is used to control the output power of the laser welding assembly and the electrode welding assembly; and a wire feeding speed setting module, which is coupled to the electrode welding assembly, and is used to control the movement speed of the welding wire.
[0015] To address the aforementioned problems, this application also provides a control method for a composite welding apparatus, comprising: a first control element determining whether an electrode welding assembly is short-circuited; if the electrode welding assembly is short-circuited, the first control element controls the welding wire of the electrode welding assembly to move away from the weld point of the welding component, the first control element controls the electrode welding assembly to output low energy or not work, and transmits a synchronization signal to a second control element, the second control element controls the laser welding assembly to output normal energy; if the short circuit of the electrode welding assembly ends, the first control element controls the welding wire of the electrode welding assembly to move close to the weld point of the welding component, the first control element controls the electrode welding assembly to output normal energy, and transmits a synchronization signal to the second control element, the second control element controls the laser welding assembly to output low energy or not work.
[0016] The step of the first control unit determining whether the electrode welding assembly is short-circuited includes: the first control unit collecting the arc current of the welding wire and determining whether the electrode welding assembly is short-circuited based on the arc current.
[0017] The process includes the following steps: the first control unit collects the arc current of the welding wire, and determines whether the electrode welding assembly is short-circuited based on the arc current. Then, the following steps are followed: a power setting module collects the average power of the electrode welding assembly and the laser welding assembly; the average power is transmitted to the first control unit and the second control unit respectively to control the instantaneous power of the welding wire and the laser emitter; a wire feeding speed setting module collects the average wire feeding speed of the welding wire; the average wire feeding speed is transmitted to the first control unit, and the first control unit controls the instantaneous speed at which the welding wire is moved by the welding wire fixing component.
[0018] In the event of a short circuit in the electrode welding assembly, the first control unit controls the welding wire of the electrode welding assembly to move away from the welding point of the welding component, the first control unit controls the electrode welding assembly to output low energy or not work, and transmits a synchronization signal to the second control unit. The steps of the second control unit controlling the normal energy output of the laser welding assembly include: the first control unit controls the welding wire fixing component to move the welding wire away from the welding point; the first control unit transmits a synchronization signal to the second control unit, and the second control unit controls the laser emitting component to emit laser light.
[0019] The steps of the electrode welding assembly, after the short circuit ends, include: the first control unit controls the welding wire of the electrode welding assembly to approach the weld point of the welding component; the first control unit controls the electrode welding assembly to output normal energy and transmits a synchronization signal to the second control unit; and the second control unit controls the laser welding assembly to output low energy or not work.
[0020] This application sets up the laser welding assembly and the electrode welding assembly to correspond to the same welding component. The electrode welding assembly and the laser welding assembly communicate with each other through a synchronization signal. At the same time, one of the electrode welding assembly and the laser welding assembly outputs normal energy while the other outputs low energy or does not work. This avoids the welding liquid splashing onto the laser welding assembly and thus affecting the output efficiency of the laser. It also avoids arc fluctuations and shielding gas disturbances caused by laser output, thus ensuring the stability of the welding between the laser welding assembly and the electrode welding assembly.

[0036] Please refer to Figure 1, which is a structural block diagram of an embodiment of the composite welding apparatus provided in this application.
[0037] This application provides a composite welding apparatus, as shown in FIG1. The composite welding apparatus of this embodiment includes an electrode welding assembly 10 and a laser welding assembly 20. The laser welding assembly 20 is correspondingly arranged with the electrode welding assembly 10 and coupled to it. The electrode welding assembly 10 and the laser welding assembly 20 are arranged correspondingly with the same welding component 30. The electrode welding assembly 10 and the laser welding assembly 20 communicate through a synchronization signal so that one of the electrode welding assembly 10 and the laser welding assembly 20 outputs normal energy at the same time, while the other outputs low energy or does not work. Both the electrode welding assembly 10 and the laser welding assembly 20 are connected to the welding component 30 and can be used to heat the welding component 30. The electrode welding assembly 10 and the laser welding assembly 20 can be correspondingly arranged on both sides of the welding component 30, which is not specifically limited here.
[0038] Generally, when the electrode welding assembly 10 and the laser welding assembly 20 operate simultaneously, the molten welding liquid produced by the electrode welding assembly 10 melting the welding wire 103 on the welding component 30 will splash onto the lens of the laser welding assembly 20, causing a decrease in the laser output efficiency emitted by the laser welding assembly 20, thus reducing the welding quality of the welding component 30. Furthermore, when the laser welding assembly 20 is operating, it emits a laser to weld the weld points on the welding component 30. However, when the laser welding assembly 20 heats the weld points, the welding wire 103 of the electrode welding assembly 10 melts and forms a molten pool on the weld point of the welding component 30. The laser emitted by the laser welding assembly 20 will agitate this molten pool. At this time, the welding wire 103 of the electrode welding assembly 10 is also on the weld point of the welding component 30. The laser emitted by the laser welding assembly 20 will cause gas turbulence and arc fluctuations in the electrode welding assembly 10, further reducing the welding quality of the electrode welding assembly 10. Furthermore, it will further heat the welding wire 103 of the electrode welding assembly 10, causing the melting characteristics of the welding wire 103 to change. When the welding wire 103 is heated, the molten welding liquid of the welding wire 103 will splash more violently, thereby further affecting the laser transmission efficiency of the laser welding assembly 20.
[0039] In an optional embodiment, as shown in Figure 2, after the electrode welding assembly 10 and the laser welding assembly 20 heat the welding component 30, the electrode welding assembly 10 and the laser welding assembly 20 work together. When one outputs normal energy, the other outputs low energy or does not work. Specifically, when the electrode welding assembly 10 starts working, the electrode welding output power melts the welding wire 103 of the electrode welding assembly. At this time, the welding wire 103 is away from the welding component 30 and is in a molten state. When the welding wire 103 melts and is about to drip, the electrode welding assembly 10 moves the welding wire 103 toward the weld point of the part to be welded, so that the welding liquid of the welding wire 103 drips onto the weld point of the welding component 30. Since the electrode welding assembly is connected to the welding component 30 and the welding wire 103 is in contact with the welding component 30, the welding wire 103 is in a short-circuit state at this time. When the electrode welding assembly 10 detects the short circuit, the electrode welding assembly 10 outputs low energy or does not work. When the electrode welding assembly 10 has low energy output or is not working, the electrode welding assembly 10 controls the welding wire 103 to move away from the welding point of the welding component 30. When the electrode welding assembly 10 has low energy output or is not working, the electrode welding assembly 10 transmits a synchronization signal to the laser welding assembly 20. After receiving the synchronization signal, the laser welding assembly 20 emits a laser to heat the welding liquid on the welding point of the welding component 30, and welds the welding point of the welding component 30 with the welding liquid melted by the welding wire 103 of the electrode welding assembly 10.
[0040] In this embodiment, when the laser welding assembly 20 starts working, it emits a laser to melt the molten welding wire 103. Upon contact with the welding component 30, the welding wire 103 forms a short circuit, causing the electrode welding assembly 10 to output low energy or cease operation, and control the welding wire 103 to move away from the welding component 30. The electrode welding assembly 10 transmits a synchronization signal to the laser welding assembly 20, which, upon receiving the synchronization signal, outputs low energy or ceases operation. When the welding wire 103 moves away from the welding component 30, the electrode welding assembly 10 starts working, causing the point electrode welding wire 103 to begin melting. This allows the molten welding wire 103 to drip onto the welding point of the welding component 30 when it subsequently contacts the welding component 30, thereby welding the component 30. That is, by coordinating the electrode welding assembly 10 and the laser welding assembly 20 through a synchronous signal, one of the electrode welding assembly 10 and the laser welding assembly 20 will output normal energy, while the other will output low energy or not work. This effectively avoids the welding liquid splashing onto the laser welding assembly 20, which would affect the output efficiency of the laser, and also avoids arc fluctuations and shielding gas disturbances caused by laser output.
[0041] By using the above method, the laser welding assembly 20 and the electrode welding assembly 10 are set to correspond to the same welding component 30. The electrode welding assembly 10 and the laser welding assembly 20 communicate through a synchronization signal. At the same time, one of the electrode welding assembly 10 and the laser welding assembly 20 outputs normal energy, while the other outputs low energy or does not work. This avoids the welding liquid splashing onto the laser welding assembly 20, which would affect the output efficiency of the laser. It also avoids arc fluctuations and shielding gas disturbances caused by laser output, thus ensuring the stability of the welding process between the laser welding assembly 20 and the electrode welding assembly 10.
[0042] In an optional embodiment, the electrode welding assembly 10 includes a first control element 101 and a welding wire fixing element 102. The welding wire fixing element 102 is coupled to the first control element 101 and is used to fix a welding wire 103. One end of the welding wire 103 corresponds to the welding point of the laser welding assembly 20. When the electrode welding assembly 10 is working, the first control element 101 outputs power to make the welding wire 103 start to melt. After the welding wire 103 melts, the first control element 101 drives the welding wire fixing element 102 to move the welding wire 103 close to the welding point of the welding component 30, so that the welding liquid of the welding wire 103 drips onto the welding point of the welding component 30. After the welding wire fixing element 102 moves the welding wire 103 and abuts against the welding component 30, the first control element 101 detects that the welding wire 103 is in a short circuit state. The first control element 101 transmits a synchronization signal to the laser welding assembly 20, and the laser welding assembly 20 outputs laser energy to heat the welding liquid on the welding point. When the first control unit 101 abuts the welding wire 103 against the welding component 30, and the first control unit 101 detects that the welding wire 103 is short-circuited, the first control unit 101 drives the welding wire fixing component 102 to move the welding wire 103 away from the welding point position of the welding component 30. The first control unit 101 then starts working, putting the welding wire 103 into an arc-ignition state. When the welding wire 103 of the electrode welding assembly 10 is in an arc-ignition state, the first control unit 101 transmits a synchronization signal to the laser welding assembly 20. The laser welding assembly 20 then outputs low energy or stops working, preventing the output power of the laser welding assembly 20 from affecting the arc-ignition state of the welding wire 103.
[0043] In this embodiment, the welding wire fixing member 102 is a movable component. Under the control of the first control member 101, it drives the welding wire 103 to reciprocate, thereby moving the welding wire 103 closer to or away from the welding point of the laser welding assembly 20. That is, after the first control member 101 controls the welding wire 103 to ignite an arc and it becomes molten in the arc state, the first control member 101 controls the welding wire fixing member 102 to move the welding wire 103 closer to the welding point of the welding component 30. When the welding wire 103 contacts the welding point of the welding component 30, if the first control member 101 detects that the welding wire 103 is in a short-circuit state, the first control member 101 controls the welding wire 103 to output low energy or not work, and drives the welding wire fixing member 102 to move the welding wire 103 away from the welding point of the welding component 30.
[0044] In an optional embodiment, the laser welding assembly 20 includes a second control element 201 and a laser emitter 202. The second control element 201 communicates with the first control element 101 via a synchronization signal. The second control element 201 is coupled to the laser emitter 202, and the axial direction of the laser emitter 202 is set at a preset angle to the axial direction of the welding wire 103. When the electrode welding assembly 10 starts working, the first control element 101 drives the welding wire 103 to start arcing, causing the welding wire 103 to melt and form a molten state. That is, the first control element 101 controls the welding wire fixing element 102 to start. The welding wire fixing element 102 drives the molten welding wire 103 to approach the welding point of the welding component 30, so that the molten welding liquid on the welding wire 103 drips onto the welding point. After the welding wire 103 contacts the welding point of the welding component 30, the first control element 101 detects that the welding wire 103 is in a short circuit state, and the first control element 101 outputs low energy or does not work. The first control unit 101 transmits a synchronization signal to the second control unit 201. Upon receiving the synchronization signal, the second control unit 201 controls the laser emitter 202 to emit a laser, thereby heating the molten welding liquid dripping onto the welding joint of the welding component 30. When the first control unit 101 detects that the welding wire 103 is in a short-circuit state, the first control unit 101 drives the welding wire fixing member 102 to start, so that the welding wire fixing member 102 moves the welding wire 103 away from the welding joint of the welding component 30. After the welding wire 103 is separated from the welding joint of the welding component 30, the first control unit 101 controls the welding wire 103 to ignite an arc. The first control unit 101 transmits a synchronization signal to the second control unit 201. Upon receiving the synchronization signal, the second control unit 201 controls the laser emitter 202 to output low energy or not to operate. That is, by communicating with the first control unit 101 through a synchronization signal via the second control unit 201, the coordinated operation of the electrode welding assembly 10 and the laser welding assembly 20 can be effectively controlled, thereby avoiding mutual interference between the laser welding assembly 20 and the electrode welding assembly 10 during operation. The axis of the laser emitter 202 is set at a preset angle to the axis of the welding wire 103, thus facilitating the welding cooperation between the electrode welding assembly 10 and the laser welding assembly 20.
[0045] In an optional embodiment, as shown in FIG2, the composite device further includes a power setting module 40, which is coupled to the electrode welding assembly 10 and the laser welding assembly 20. The power setting module is used to control the output power of the laser welding assembly 20 and the electrode welding assembly 10. When the laser welding assembly 20 and the electrode welding assembly 10 are working, the power setting module 40 can collect the power of the electrode welding assembly 10 and the laser welding assembly 20 during operation, and calculate the average power of the electrode welding assembly 10 and the laser welding assembly 20 during operation. When the laser welding assembly 20 and the electrode welding assembly 10 are working, that is, when the first control element 101 controls the welding wire 103 to ignite and melt, and when the second control element 201 controls the laser emitter 202 to emit laser light, the power setting module 40 sets the average power to the first control element 101 and the second control element 201, thereby controlling the instantaneous power when the welding wire 103 melts and the laser emitter 202 is working. This avoids the problem of unstable welding due to excessive power or poor welding effect due to insufficient power when the electrode welding assembly 10 and the laser welding assembly 20 are working. In this embodiment, the composite welding device also includes a wire feeding speed setting module 50, which is coupled to the electrode welding assembly 10 and is used to control the movement speed of the welding wire 103. When the electrode welding assembly 10 is working, the wire feeding speed setting module 50 can collect the speed at which the welding wire 103 moves in the electrode welding assembly 10, that is, the operating speed of the welding wire fixing member 102 when it is working. The first control member 101 calculates the average wire feeding speed of the welding wire fixing member 102 when the welding wire 103 moves based on the collected moving speed of the welding wire 103. When the electrode welding assembly 10 is working, the wire feeding speed setting module 50 sets the average wire feeding speed to the first control member 101, thereby controlling the operating speed of the welding wire fixing member 102 through the first control member 101. This effectively avoids the welding wire 103 moving too fast or too slow, which would result in poor melting effect of the welding wire 103 or the welding liquid dripping to other places, causing deviation in the welding effect. In other embodiments, the wire feeding speed setting module 50 can work with the first control component 101 and the welding wire fixing component 102 to control the acceleration of the welding wire 103 when it moves. The wire feeding speed setting module 50 can control the wire feeding speed according to actual needs, and this application does not make specific limitations here.
[0046] In a specific application scenario, when the electrode welding assembly 10 and the laser welding assembly 20 are welding the welding component 30, the power setting module 40 is activated. The first control unit 101 controls the welding wire 103 to arc and melt into a molten state. The first control unit 101 also controls the welding wire fixing component 102 to start. The welding wire fixing component 102 drives the welding wire 103 to approach the welding point of the welding component 30. When the welding wire 103 touches the welding point of the welding component 30, the first control unit 101 detects that the welding wire 103 is in a short-circuit state. The first control unit 101 transmits a synchronization signal to the second control unit 201. The second control unit 201 controls the laser emitting component 202 to emit a laser, thereby melting the molten welding liquid of the welding wire 103. When the first control unit 101 detects that the welding wire 103 is in a short-circuit state, the first control unit 101 controls the welding wire fixing member 102 to move the welding wire 103 away from the welding point of the welding component 30, and controls the welding wire 103 to ignite and melt. A synchronization signal is transmitted to the second control unit 201, which controls the laser emitter 202 to output low energy or not operate, to prevent the laser emitter 202 from affecting the stability of the electrode welding assembly 10 when the welding wire 103 melts. The power setting module 40 calculates the power of the welding wire 103 when it ignites and the laser emitter 202 when it emits laser light, and obtains the average power. In subsequent instances of the welding wire 103 igniting and the laser emitter 202 emitting laser light, it provides the instantaneous power. The wire feed speed setting module 50 can obtain the average speed of the welding wire 103 during movement, and provides the instantaneous speed of the welding wire 103 during subsequent movements.
[0047] In the above embodiments, by setting the laser welding assembly 20 and the electrode welding assembly 10 to correspond to the same welding component 30, and by communicating synchronously via a real-time signal, one of the laser welding assembly 20 and the electrode welding assembly 10 can output normal energy, while the other outputs low energy or does not work. This avoids the welding molten metal splashing onto the laser welding assembly 20, thus preventing it from affecting the laser output efficiency, and also avoids arc fluctuations and shielding gas disturbances caused by laser output, ensuring the stability of the welding process between the laser welding assembly 20 and the electrode welding assembly 10. By setting a first control element 101 and a welding wire fixing element 102, as well as a second control element 201 and a laser transmitter, the first control element 101 can control the welding wire fixing element 102 to move the welding wire 103 closer to or away from the welding component 30. The first control element 101 transmits a synchronous signal to the second control element, thereby ensuring that one of the electrode welding assembly 10 and the laser welding assembly 20 is working while the other is not. By setting the axis of the laser emitter 202 at a preset angle to the axis of the welding wire 103, it is easier for the electrode welding assembly 10 and the laser welding assembly 20 to cooperate in welding. By setting the power setting module 40, the efficiency of the welding wire 103 and the laser emitter 202 during operation can be set.
[0048] Please refer to Figure 3, which is a flowchart illustrating the first embodiment of the control method for the composite welding apparatus of this application. It should be noted that if substantially the same result is achieved, the method of this application is not limited to the flow sequence shown in Figure 3. As shown in Figure 3, the method includes the following steps:
[0049] S11: The first control unit 101 determines whether the electrode welding assembly 10 is short-circuited.
[0050] In an optional embodiment, the first control element 101 can detect whether the welding wire 103 is in contact with the weld point of the welding component 30. If the welding wire 103 is in contact with the weld point of the welding component 30, it can be determined that the electrode welding assembly 10 is in a short-circuit state. If the welding wire 103 is disengaged from the weld point of the welding component 30, that is, the end of the welding wire 103 is not in contact with the weld point of the welding component 30, it can be determined that the electrode welding assembly 10 is in a working state, that is, the electrode welding assembly 10 is not short-circuited.
[0051] S12: If the electrode welding assembly 10 is short-circuited, the first control unit 101 controls the welding wire 103 of the electrode welding assembly 10 to move away from the welding point of the welding component 30, the first control unit 101 controls the electrode welding assembly 10 to output low energy or not work, and transmits the synchronization signal to the second control unit 201, the second control unit 201 controls the laser welding assembly 20 to output normal energy.
[0052] In an optional embodiment, when the electrode welding assembly 10 is short-circuited, i.e., the welding wire 103 of the electrode welding assembly 10 contacts the weld point of the welding component 30, the first control unit 101 detects that the welding wire 103 is in a short-circuit state. The first control unit 101 controls the welding wire fixing member 102 to start, and the welding wire fixing member 102 moves the welding wire 103 away from the weld point of the welding component 30. The first control unit 101 transmits a synchronization signal to the second control unit 201. After receiving the synchronization signal, the second control unit 201 controls the laser assembly to output energy normally.
[0053] In this embodiment, when the welding wire 103 is in a short-circuit state, the molten welding wire 103 drips the molten welding liquid onto the weld joint of the welding part. At this time, the second control unit 201 controls the laser emitter 202 to emit a laser to heat the molten welding liquid dripping onto the weld joint, thereby welding the weld joint of the welding component 30. Furthermore, while the laser emitter 202 is emitting a laser to heat the molten welding liquid, the first control unit 101 controls the welding wire 103 to be in low-energy output or not working, preventing the welding wire 103 from arcing and causing the molten welding liquid to splash onto the lens of the laser emitter 202, thus reducing the efficiency of laser transmission by the laser emitter 202.
[0054] S13: After the short circuit of the electrode welding assembly 10 ends, the first control unit 101 controls the welding wire 103 of the electrode welding assembly 10 to be close to the welding point of the welding component 30, the first control unit 101 controls the electrode welding assembly 10 to output normal energy, and transmits the synchronization signal to the second control unit 201, the second control unit 201 controls the laser welding assembly 20 to output low energy or not work.
[0055] In an optional embodiment, after the first control element 101 activates the welding wire fixing element 102, the welding wire fixing element 102 drives the welding wire 103 away from the welding point of the welding component 30, that is, the welding wire 103 disengages from the welding component 30. The welding wire 103 is no longer in contact with the welding component 30, and the first control element 101 detects that the welding wire 103 is not in a short-circuit state. The first control element 101 then controls the welding wire 103 to ignite an arc, causing the welding wire 103 to melt. While the welding wire 103 is melting, the first control element 101 transmits a synchronization signal to the second control element 201. After detecting the synchronization signal, the second control element 201 controls the laser welding assembly 20 to operate at low energy output or normal energy output.
[0056] In this embodiment, when the first control element 101 controls the welding wire 103 to be in an arc-burning state, that is, when the welding wire 103 is far away from the welding point position of the welding component 30, the second control element 201 receives the synchronization signal from the first control element 101 and controls the laser emitter 202 to output low energy or not work. That is, when the welding wire 103 is arc-burning, the laser emitter 202 outputs low energy or does not work, thereby effectively avoiding the laser emitter 202 emitting laser when the welding wire 103 is arc-burning, which would cause shielding gas disturbance and arc fluctuation when the welding wire 103 is arc-burning, thus reducing the melting efficiency of the welding wire 103.
[0057] In an optional embodiment, after the first control element 101 detects that the short circuit of the electrode welding assembly 10 has ended, i.e., the welding wire 103 has detached from the weld point of the welding component 30, the first control element 101 controls the welding wire 103 to start arcing. When the welding wire 103 starts arcing, in order to improve the melting effect of the welding wire 103, after the first control element 101 detects that the short circuit of the welding wire 103 has ended, the first control element 101 can control the welding wire fixing element 102 to continue retracting the welding wire 103. The welding wire 103 continues to move away from the weld point of the welding component 30. That is, after the welding wire detaches from the weld point of the welding component 30, the welding wire fixing element 30 can control the welding wire 103 to retract for a specific time or a specific distance, thereby improving the melting effect of the welding wire 103.
[0058] In a specific application scenario, after the electrode welding assembly 10 short-circuits, i.e., after the welding wire 103 detaches from the weld point of the welding component 30, the first control component 101 controls the welding wire fixing component 102 to continue retracting the welding wire 103. After the welding wire fixing component 102 retracts the welding wire 103 to a specific time or a specific distance, the first control component 101 controls the welding wire fixing component 102 to return the welding wire, i.e., the welding wire fixing component 102 controls the welding wire 103 to move towards the weld point of the welding component 30. After the electrode welding assembly 10 short-circuits, during the retraction of the welding wire 103 to a specific distance or for a specific time, and during the time the welding wire 103 contacts the weld point of the welding component 30, it is necessary to ensure the melting effect of the welding wire 103. The retraction time and distance of the welding wire 103 can be set according to the output power of the electrode welding assembly 10, ensuring that the welding wire 103 melts into a molten weld and that the molten weld does not drip to other places; this application does not impose specific limitations on these aspects.
[0059] In this manner, when the first control element 101 controls the welding wire 103 to operate, the second control element 201 controls the laser emitter 202 to output low energy or not operate, thereby avoiding the shielding gas disturbance caused by the laser emission of the laser emitter 202 and preventing it from affecting the arc ignition of the welding wire 103 and thus reducing the melting efficiency of the welding wire 103. When the second control element 201 controls the laser emitter 202 to emit laser, the first control element 101 controls the welding wire 103 to output low energy or not operate, thereby preventing the molten welding liquid from splashing onto the lens of the laser emitter 202 when the welding wire 103 is melting, thus preventing the output efficiency of the laser emitter 202 from being reduced.
[0060] The welding wire fixing component 102 drives the welding wire 103 to approach or move away from the welding point at a frequency ranging from 70 Hz to 200 Hz, which can be set according to actual welding needs. This application does not impose a specific limitation here. That is, the high-frequency reciprocating movement of the welding wire 103 is controlled by the first control component 101. When the first control component 101 controls the welding wire 103 to move away from the welding point of the welding component 30, the second control component 201 can control the laser emitting component 202 to emit laser light. This avoids the situation where the welding liquid at the welding point cools down during the period when the welding wire 103 has low energy output or is not working, thus effectively improving the welding effect of the welding component 30.
[0061] Please refer to Figure 4, which is a flowchart illustrating an embodiment of S11 in Figure 3. Specifically, S11 may further include the following steps:
[0062] S111: The first control unit 101 collects the arc current of the welding wire 103 and determines whether the electrode welding assembly 10 is short-circuited based on the arc current.
[0063] In an optional embodiment, a data acquisition module (not shown) may be provided in the first control unit 101. The data acquisition module can acquire the arc current of the welding wire 103, and thereby determine whether the electrode welding assembly 10 is short-circuited based on the arc current acquired by the data acquisition module.
[0064] In this embodiment, when the acquisition module detects no current in the welding wire 103 of the electrode welding assembly 10, the first control element 101 determines that the welding wire 103 of the electrode welding assembly 10 is in a short-circuit state, that is, the welding wire 103 of the electrode welding assembly 10 is in contact with the weld point of the welding component 30. When the acquisition module detects current in the welding wire 103 of the electrode welding assembly 10, the first control element 101 determines that the welding wire 103 of the electrode welding assembly 10 is in an arc-ignition state, that is, the first control element 101 controls the welding wire 103 to ignite and melt.
[0065] S112: The power input module 40 collects the average power of the electrode welding assembly 10 and the laser welding assembly 20.
[0066] In an optional embodiment, when the first control unit 101 and the second control unit 201 control the welding wire 103 and the laser emitter 202 to work respectively, the acquisition module acquires the power of the electrode welding assembly 10 and the laser welding assembly 20. After acquiring the power of the electrode welding assembly 10 and the laser welding assembly 20 when they are in normal energy output, the acquired power is calculated to obtain the average power of the electrode welding assembly 10 and the laser welding assembly 20 when they are in normal energy output.
[0067] In other embodiments, the power input module 40 acquires the power of the arc burning of the electrode welding assembly 10 and the power of the laser emitted by the laser welding assembly 20. The acquisition module can acquire the power of the arc burning of the welding wire 103 and the power of the laser emitted by the laser welding assembly 20.
[0068] S113: The average power is transmitted to the first control unit 101 and the second control unit 201 respectively, so as to control the instantaneous power of the welding wire 103 and the laser emitter 202 respectively.
[0069] In an optional embodiment, after the power setting module 40 collects the power of the arc ignition of the welding wire 103 of the electrode welding assembly 10 and the power of the laser emitted by the laser emitter 202, it calculates the average power of the electrode welding assembly 10 and the laser welding assembly 20 during operation. After obtaining the average power, the instantaneous power of the arc ignition of the electrode welding assembly 10 is controlled by the first control unit 101, and the instantaneous power of the transmission of the laser emitted by the laser emitter 202 is controlled by the second control unit 201.
[0070] In a specific application scenario, the power input module 40 acquires the power of the welding wire 103 during arc ignition in the electrode welding assembly 10 and calculates the first average power of the welding wire 103 during arc ignition. The power input module 40 also acquires the power of the laser emitted by the laser welding assembly 20 and calculates the second average power of the laser emitted by the laser emitter 202. When the first controller 101 controls the welding wire 103 to ignite the arc, the acquisition module transmits the calculated first average power to the first controller 101. The first controller 101 receives the first average power and controls the welding wire 103 to ignite the arc at the first average power. When the second controller 201 controls the laser emitter 202 to emit the laser, the acquisition module transmits the calculated second average power to the second controller 201. The second controller 201 receives the second average power and controls the laser emitter 202 to emit the laser at the second average power.
[0071] S114: Wire feed speed setting module 50 collects the average wire feed speed of welding wire 103.
[0072] In this embodiment, when the first control unit 101 controls the electrode welding assembly 10 to start working, that is, when the welding wire 103 is outputting normal power, the wire feeding speed setting module 50 collects the wire feeding speed of the welding wire fixing member 102, that is, the moving speed of the welding wire 103, and the wire feeding speed setting module calculates the average speed of the moving welding wire 103.
[0073] S115: The average wire feeding speed is transmitted to the first control unit 101, and the first control unit 101 controls the instantaneous speed at which the welding wire fixing unit 102 drives the welding wire 103 to move.
[0074] In this embodiment, after the wire feeding speed setting module 50 calculates the average speed of the welding wire 103 when it moves, it transmits the average speed to the first control unit 101. The first control unit 101 obtains the average wire feeding speed and controls the operating speed of the welding wire fixing member 102 so that the welding wire fixing member 102 drives the welding wire 103 to move at the average wire feeding speed.
[0075] The power setting module 40 and the wire feeding speed setting module 50 can be collected simultaneously. Alternatively, the wire feeding speed setting module 50 can be used to first collect the speed of the welding wire 103, and then the power setting module 40 can be used to collect the output power of the electrode welding assembly 10 and the laser welding assembly 20. This application does not make specific limitations here.
[0076] Please refer to Figure 5, which is a flowchart illustrating an embodiment of S12 in Figure 3. Specifically, S12 may further include the following steps:
[0077] S121: The first control component 101 controls the welding wire fixing component 102 to move the welding wire 103 away from the welding point.
[0078] In an optional embodiment, the electrode welding assembly 10 is short-circuited, i.e., the welding wire 103 abuts against the weld point of the welding component 30, and the welding wire 103 of the electrode welding assembly 10 has low energy output or is not working. The first control member 101 drives the welding wire fixing member 102 to move the welding wire 103 away from the weld point of the welding component 30. After the first control member 101 drives the welding wire fixing member 102 to move the welding wire 103 away from the weld point of the welding component 30, the first control member 101 can control the arc of the welding wire 103.
[0079] S122: The first control unit 101 transmits the synchronization signal to the second control unit 201, and the second control unit 201 controls the laser emitter 202 to emit laser.
[0080] Specifically, when the welding wire 103 of the electrode welding assembly 10 contacts the weld joint of the welding component 30, the first control unit 101 controls the welding wire 103 to output low energy or not work. The first control unit 101 transmits a synchronization signal to the second control unit 201 in real time. After receiving the synchronization signal transmitted by the first control unit 101, the second control unit 201 controls the laser emitter 202 to emit a laser.
[0081] In this embodiment, when the electrode welding assembly 10 is short-circuited, the first control unit 101 controls the welding wire 103 to output low energy or not work, and controls the laser emitting unit 202 to emit laser through the second control unit 201, which can heat the molten welding liquid of the welding wire 103 and prevent the welding liquid from cooling.
[0082] Please refer to Figure 6, which is a flowchart illustrating an embodiment of S13 in Figure 3. Specifically, S13 may further include the following steps:
[0083] S131: The first control component 101 controls the welding wire fixing component 102 to drive the welding wire 103 to approach the welding point.
[0084] In this embodiment, when the electrode welding assembly 10 is outputting normal energy, i.e., the welding wire 103 is far from the welding point of the welding component 30, the first control unit 101 controls the welding wire fixing member 102 to move the welding wire 103 closer to the welding point of the welding component 30. When the welding wire 103 separates from the welding point of the welding component 30, the power setting module 40 transmits the calculated average power to the first control unit 101, and the first control unit 101 controls the output of the average power. After the first control unit 101 controls the welding wire 103 to melt and form a molten welding liquid, the first control unit 101 drives the welding wire fixing member 102 to move the welding wire 103 closer to the welding point of the welding component 30.
[0085] S132: The first control unit 101 transmits the synchronization signal to the second control unit 201, and the second control unit 201 controls the laser emitter 202 to output low energy or not work.
[0086] In this embodiment, when the first control element 101 controls the welding wire 103 to ignite the arc, that is, when the welding wire 103 is in a molten state, the first control element 101 transmits a synchronization signal to the second control element 201. The second control element 201 controls the laser emitter 202 to operate at low energy output or not operate. While the first control element 101 controls the welding wire 103 to ignite the arc and the welding wire 103 is not in contact with the weld joint of the welding component 30, the second control element 201 controls the laser emitter 202 to operate at low energy output or not operate, so as to avoid the laser emitted by the laser emitter 202 affecting the transmission efficiency of the electrode welding assembly 10 and causing shielding gas disturbance.
[0087] In other embodiments, when the first control element 101 controls the arc of the welding wire 103, the arc length of the arc can be specifically controlled by an arc length control module (not shown). This ensures that when the welding wire 103 is far from the welding point, the arc length will not contact the welding point of the welding component 30, thus preventing excessively long short-circuit time and excessively short arc time. Consequently, the welding wire 103 will have poor melting effect during operation. When the welding wire 103 subsequently contacts the welding point of the welding component 30, the adhesion between the welding liquid and the welding component 30 will be poor, causing the welding liquid to drip into areas outside the welding point of the welding component 30. This avoids the occurrence of poor welding effect.
[0088] In a specific application scenario, when the composite welding device welds the welding component 30, the electrode welding assembly 10 and the laser welding assembly 20 work alternately. That is, when the electrode welding assembly 10 is outputting normal energy, the laser welding assembly 20 is outputting low energy or not working, and vice versa. The electrode welding assembly 10 operates in a cycle of arc ignition-short circuit-arc ignition. During the arc ignition stage, an electric arc is ignited between the end of the welding wire 103 and the welding point of the welding component 30. Under the action of the arc, the end of the welding wire 103 begins to melt, gradually forming molten droplets. At this time, the first control component 101 controls the welding wire fixing component 102 to work. The welding wire fixing component 102 moves the welding wire 103 closer to the welding point on the welding component 30, and the molten droplets fall onto the welding point to form a molten pool for welding the welding component 30. During this process, the laser welding assembly 20 outputs low energy or is not working. After the welding wire 103 contacts the weld point of the welding component 30, the electrode welding assembly 10 is in a short-circuit state. At this time, the electrode welding assembly outputs low energy or does not work. The first control unit 101 transmits a synchronization signal to the second control unit 201, which controls the laser emitter 202 to emit a laser to heat the molten pool. After the welding wire 103 contacts the weld point of the welding component 30 and drips molten metal onto the weld point, the welding wire fixing unit 102 controls the welding wire 103 to move away from the weld point of the welding component 30. At this time, the short circuit ends, and the electrode welding assembly 10 restarts, that is, the welding wire 103 starts to ignite an arc. The above steps are repeated until the welding of the welding component 30 is completed, and both the electrode welding assembly 10 and the laser welding assembly 20 output low energy or do not work.
[0089] In the above manner, the first control component 101 and the second control component 201 communicate in real time via a synchronous signal. When the electrode welding component 10 is working, the laser welding component 20 outputs low energy or does not work, and when the laser welding component 20 is working, the electrode welding component 10 outputs low energy or does not work. This prevents the molten weld from splashing onto the lens of the laser emitter 202 during welding, thus avoiding a decrease in the laser emission efficiency of the laser emitter 202, and also preventing the welding wire 103 from melting efficiently and causing shielding gas disturbances when the welding wire 103 is ignited. This effectively improves the efficiency and quality of welding.
