[0002] With the development of science and technology, welding technology is needed to combine workpieces in fields such as mechanical manufacturing, among which metal welding plays an important role. Metal welding is a manufacturing or sculpture process of connecting metals. During the welding process, the workpiece and the solder melt or do not melt, forming a weld that directly connects the materials. In this process, pressure is usually required to join the weldment. In order to improve the welding effect, electrode welding and laser welding are often required to weld the workpieces.

[0003] However, when electrode welding and laser welding are combined, the welding liquid of electrode welding will splash onto the laser lens during welding, thereby contaminating the laser lens, causing a decrease in laser transmission efficiency and subsequently a decrease in welding quality. In addition, laser welding will stir the molten pool during welding, causing turbulence in the shielding gas and arc fluctuations in electrode welding. It will also heat the welding wire, causing changes in the melting characteristics of the welding wire, thereby affecting the welding stability of electrode welding, which in turn increases welding spatter, and then causes a decrease in the power of the laser emitted by laser welding, thereby affecting the welding effect of the workpiece.

[0025] See also Figure 1 , Figure 1 It is a structural block diagram of an embodiment of a composite welding device provided in the present application.

[0026] The present application provides a welding device, such as Figure 1 As shown, the composite welding device of this embodiment includes: an electrode welding assembly 10 and a laser welding assembly 20. The laser welding assembly 20 is arranged corresponding to the electrode welding assembly 10, the laser welding assembly 20 is coupled to the electrode welding assembly 10, the laser welding assembly 20 is arranged corresponding to the electrode welding assembly 10, the laser welding assembly 20 is coupled to the electrode welding assembly 10, the electrode welding assembly 10 and the laser welding assembly 20 are arranged corresponding to the same welding component 30, and the electrode welding assembly 10 and the laser welding assembly 20 communicate through a synchronization signal so that at the same time, one of the electrode welding assembly 10 and the laser welding assembly 20 outputs normal energy, and the other outputs low energy or does not work. Among them, the electrode welding assembly 10 and the laser welding assembly 20 are both connected to the welding component 30, which can be used to heat the welding component 30, and the electrode welding assembly 10 and the laser welding assembly 20 can be arranged on both sides of the welding component 30, which is not specifically limited in this application.

[0027] Generally speaking, when the electrode welding assembly 10 and the laser welding assembly 20 work simultaneously, when the electrode welding assembly 10 melts the welding wire 103 on the welding component 30, the melted welding liquid will splash, and the splashed welding liquid will splash onto the lens of the laser welding assembly 20, resulting in a decrease in the laser output efficiency emitted by the laser welding assembly 20, thereby reducing the welding quality of the welding component 30. When the laser welding assembly 20 is working, the laser welding assembly 20 emits a laser to weld the welding point of the welding component 30. However, when the laser welding assembly 20 emits a laser to heat the welding point, the welding wire 103 of the electrode welding assembly 10 melts and forms a welding liquid molten pool on the welding point of the welding component 30, and the laser emitted by the laser welding assembly 20 will stir the molten pool. At this time, the welding wire 103 of the electrode welding assembly 10 is also on the welding point of the welding component 30, and the laser emitted by the laser welding assembly 20 will cause gas turbulence and the arc of the electrode welding assembly 10 to be moved, so that the welding quality of the electrode welding assembly 10 is reduced. 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, and when the welding wire 103 is heated, the melted welding liquid of the welding wire 103 will splash more violently, thereby further causing the laser transmission efficiency of the laser welding assembly 20.

[0028] In an optional embodiment, in combination Figure 2 As shown, after the electrode welding assembly 10 and the laser welding assembly 20 heat the welding part 30, the electrode welding assembly 10 and the laser welding assembly 20 work together, one of which outputs normal energy, and the other outputs low energy or does not work. Specifically, when the electrode welding assembly 10 starts to work, the electrode welding output power causes the welding wire 103 of the electrode welding assembly to melt. At this time, the welding wire 103 of the electrode welding is away from the welding part 30, and the welding wire 103 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 to the welding point of the part to be welded, so that the welding liquid of the welding wire 103 drips on the welding point of the welding part 30. Since the electrode welding is connected to the welding part 30, and the welding wire 103 contacts the welding part 30, the welding wire 103 of the electrode welding assembly 10 is in a short-circuit state at this time. When the electrode welding assembly 10 detects a short circuit, the electrode welding assembly 10 outputs a low energy output 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 stay 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 the welding liquid melted by the welding wire 103 of the electrode welding assembly 10 is used to weld the welding point of the welding component 30.

[0029] In this embodiment, when the laser welding assembly 20 starts to work, the laser welding assembly 20 emits a laser to melt the welding liquid of the welding wire 103, and the welding wire 103 of the electrode welding forms a short circuit after contacting the welding part 30, and the electrode welding assembly 10 outputs low energy or does not work, and controls the welding wire 103 to be away from the welding part 30. The electrode welding assembly 10 transmits a synchronization signal to the laser welding assembly 20, and the laser welding assembly 20 outputs low energy or does not work after receiving the synchronization signal. When the welding wire 103 of the electrode welding is away from the welding part 30, the electrode welding assembly 10 starts to work, so that the welding wire 103 of the spot electrode welding starts to melt, so that when the welding wire 103 contacts the welding part 30 later, the welding liquid after the welding wire 103 is melted is dripped into the welding point position of the welding part 30, thereby welding the welding part 30. That is, the electrode welding assembly 10 and the laser welding assembly 20 cooperate with each other through the synchronization signal, so that one of the electrode welding assembly 10 and the laser welding assembly 20 outputs normal energy, and the other outputs low energy or does not work, which effectively avoids the welding liquid splashing to the laser welding assembly 20 and affecting the output efficiency of the laser, and avoids arc fluctuations in electrode welding and shielding gas disorder caused by laser output.

[0030] In the above manner, by setting the laser welding assembly 20 and the electrode welding assembly 10 corresponding to the same welding part 30, the electrode welding assembly 10 and the laser welding assembly 20 communicate through a synchronization signal, and the electrode welding assembly 10 and the laser welding assembly 20 output normal energy and the other low energy or do not work at the same time, thereby avoiding the welding liquid splashing to the laser welding assembly 20 and affecting the output efficiency of the laser, and avoiding the arc fluctuation of the electrode welding and the turbulence of the shielding gas during the laser output, thereby ensuring the stability of the laser welding assembly 20 and the electrode welding assembly 10 during welding.

[0031] In an optional embodiment, the electrode welding assembly 10 includes a first control component 101 and a welding wire fixing component 102, the welding wire fixing component 102 is coupled to the first control component 101, and the welding wire fixing component 102 is used to fix the welding wire 103, and 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 component 101 outputs power to make the welding wire 103 arc and start to melt. After the welding wire 103 melts, the first control component 101 drives the welding wire fixing component 102 to drive 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 component 102 drives the welding wire 103 and abuts against the welding component 30, the first control component 101 detects that the welding wire 103 is in a short circuit state, and the first control component 101 transmits a synchronization signal to the laser welding assembly 20, and the laser welding assembly 20 outputs laser at normal energy to heat the welding liquid on the welding point. When the first control component 101 brings the welding wire 103 into contact with the welding component 30, and the first control component 101 detects that the welding wire 103 is in a short circuit, the first control component 101 drives the welding wire fixing component 102 to drive the welding wire 103 away from the welding point position of the welding component 30, and the first control component 101 starts to work so that the welding wire 103 is in an arcing state. When the welding wire 103 of the electrode welding assembly 10 is in an arcing state, the first control component 101 transmits a synchronization signal to the laser welding assembly 20, and the laser welding assembly 20 outputs low energy or does not work, thereby avoiding the output power of the laser welding assembly 20 affecting the arcing state of the welding wire 103.

[0032] In this embodiment, the welding wire fixing part 102 is a movable part, which drives the welding wire 103 to do reciprocating motion under the control of the first control part 101, thereby driving the welding wire 103 close to the welding point of the laser welding assembly 20 or away from the welding point of the laser welding assembly 20. That is, after the first control part 101 controls the welding wire 103 to ignite an arc and becomes a molten state in the arcing state, the first control part 101 controls the welding wire fixing part 102 to drive the welding wire 103 close to the welding point of the welding component 30, and when the welding wire 103 contacts the welding point of the welding component 30, when the first control part 101 detects that the welding wire 103 is in a short-circuit state, the first control part 101 controls the welding wire 103 to output low energy or not work, and drives the welding wire fixing part 102 to drive the welding wire 103 away from the welding point of the welding component 30.

[0033] In an optional embodiment, the laser welding assembly 20 includes a second control component 201 and a laser emitting component 202. The second control component 201 communicates with the first control component 101 through a synchronization signal. The second control component 201 is coupled to the laser emitting component 202. The axis direction of the laser emitting component 202 is set at a preset angle with the axis direction of the welding wire 103. When the electrode welding assembly 10 starts to work, the first control component 101 drives the welding wire 103 to start arcing, so that the welding wire 103 melts to form a molten state, that is, the first control component 101 controls the welding wire fixing component 102 to start, and the welding wire fixing component 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 on the welding point. After the welding wire 103 contacts the welding point of the welding component 30, the first control component 101 detects that the welding wire 103 is in a short circuit state, and the first control component 101 outputs low energy or does not work. The first control component 101 transmits the synchronization signal to the second control component 201. After the second control component 201 receives the synchronization signal, the second control component 201 controls the laser emitting component 202 to emit laser, thereby heating the welding liquid dripping on the welding point of the welding component 30. When the first control component 101 detects that the welding wire 103 is in a short-circuit state, the first control component 101 drives the welding wire fixing component 102 to start, so that the welding wire fixing component 102 drives the welding wire 103 away from the welding point of the welding component 30. After the welding wire 103 is separated from the welding point of the welding component 30, the first control component 101 controls the welding wire 103 to ignite an arc. The first control component 101 transmits the synchronization signal to the second control component 201. After the second control component 201 receives the synchronization signal, the second control component 201 controls the laser emitting component 202 to output low energy or not work. That is, the second control component 201 communicates with the first control component 101 through a synchronization signal, which can effectively control the electrode welding assembly 10 and the laser welding assembly 20 to work together, thereby avoiding the mutual influence between the laser welding assembly 20 and the electrode welding assembly 10. Among them, the axis direction of the laser emitting component 202 and the axis direction of the welding wire 103 are set at a preset angle, so as to facilitate the electrode welding assembly 10 and the laser welding assembly 20 to cooperate with each other for welding.

[0034] In an optional embodiment, if Figure 2As shown, the composite device also includes a power setting module 40, which is coupled to the electrode welding assembly 10 and the laser welding assembly 20, and 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 when they are working, and calculate the collected power to obtain the average power of the electrode welding assembly 10 and the laser welding assembly 20 when they are working. When the laser welding assembly 20 and the electrode welding assembly 10 are working, that is, when the first control component 101 controls the arc melting of the welding wire 103, and when the second control component 201 controls the laser emitting component 202 to emit laser, the power setting module 40 sets the average power to the first control component 101 and the second control component 201, so as to control the melting of the welding wire 103 and the instantaneous power of the laser emitting component 202 when it is working, so as to avoid the problem of unstable welding due to excessive power when the electrode welding assembly 10 and the laser welding assembly 20 are working, or the problem of poor welding effect due to too little power. In this embodiment, the hybrid welding device further 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. That is, when the electrode welding assembly 10 is working, the wire feeding speed setting module 50 can collect the speed of the welding wire 103 in the electrode welding assembly 10 when it moves, that is, the operating speed of the welding wire fixture 102 when it works, and the first control component 101 calculates the average wire feeding speed of the welding wire fixture 102 when the welding wire 103 moves according to the collected moving speed of the welding wire 103. When the electrode welding assembly 10 is working, the wire feeding speed setting module 50 gives the average wire feeding speed to the first control component 101, so as to control the operating speed of the welding wire fixture 102 through the first control component 101, effectively avoiding the situation that when the welding wire 103 is moved, the moving speed of the welding wire 103 is too fast or too slow, resulting in poor melting effect of the welding wire 103 or dripping of welding liquid in other places, resulting in deviation of the welding effect. In other embodiments, the wire feeding speed setting module 50 can cooperate with the first control component 101 and the welding wire fixing component 102 to control the acceleration of the welding wire 103 during movement. 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.

[0035] In a specific application scenario, when the electrode welding assembly 10 and the laser welding assembly 20 weld the welding component 30, the power setting module 40 is started, the first control component 101 controls the welding wire 103 to ignite the arc and melt into a molten state, the first control component 101 controls the welding wire fixing component 102 to start, and 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 abuts the welding point of the welding component 30, the first control component 101 detects that the welding wire 103 is in a short-circuit state, and the first control component 101 transmits a synchronization signal to the second control component 201, and the second control component 201 controls the laser emitting component 202 to emit a laser, thereby melting the welding liquid in the molten state of the welding wire 103. When the first control component 101 detects that the welding wire 103 is in a short-circuit state, the first control component 101 controls the welding wire fixing component 102 to drive the welding wire 103 away from the welding point of the welding component 30, and controls the welding wire 103 to arc and melt, and transmits the synchronization signal to the second control component 201. The second control component 201 controls the laser emitting component 202 to output low energy or not work, so as to prevent the laser emitting component 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 when the welding wire 103 arcs and the laser emitting component 202 emits lasers, and obtains the average power. When the welding wire 103 arcs and the laser emitting component 202 emits lasers in the subsequent process, the instantaneous power of the work is given. The wire feeding speed setting module 50 can obtain the average speed of the welding wire 103 when it moves, and when the welding wire 103 moves in the subsequent process, the instantaneous speed of the movement is given.

[0036] In the above embodiment, by setting the laser welding assembly 20 and the electrode welding assembly 10 corresponding to the same welding part 30, and communicating by synchronous signal, one of the laser welding assembly 20 and the electrode welding assembly 10 can output normal energy, and the other can output low energy or not work, so as to avoid the welding liquid splashing to the laser welding assembly 20 and affecting the output efficiency of the laser, and avoid the arc fluctuation of the electrode welding and the disorder of the shielding gas during the laser output, so as to ensure the stability of the laser welding assembly 20 and the electrode welding assembly 10 during welding. By setting the first control component 101 and the welding wire fixing component 102, and the second control component 201 and the laser sending component, the first control component 101 can control the welding wire fixing component 102 to drive the welding wire 103 close to or away from the welding part 30, and the first control component 101 transmits the synchronous signal to the second control component, so that one of the electrode welding assembly 10 and the laser welding assembly 20 works and the other does not work. By setting the axis direction of the laser emitting element 202 at a preset angle to the axis direction of the welding wire 103, it is possible to facilitate the welding of the electrode welding assembly 10 and the laser welding assembly 20. By setting the power setting module 40, the efficiency of the welding wire 103 and the laser emitting element 202 during operation can be set.

[0037] See also Figure 3 , Figure 3 1 is a flow chart of the first embodiment of the control method of the composite welding device of the present application. It should be noted that if there is substantially the same result, the method of the present invention is not limited to Figure 3 The process sequence shown is limited. Figure 3 As shown, the method comprises the following steps:

[0038] S11: The first control component 101 determines whether the electrode welding assembly 10 is short-circuited.

[0039] In an optional embodiment, the first control component 101 can obtain whether the welding wire 103 is in contact with the welding point of the welding component 30. If the welding wire 103 is in contact with the welding 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 separated from the welding point of the welding component 30, that is, the end of the welding wire 103 is not in contact with the welding 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.

[0040] S12: If the electrode welding assembly 10 is short-circuited, the first control component 101 controls the welding wire 103 of the electrode welding assembly 10 to stay away from the welding point of the welding part 30. The first control component 101 controls the electrode welding assembly 10 to have low energy output or not work, and transmits the synchronization signal to the second control component 201. The second control component 201 controls the laser welding assembly 20 to have normal energy output.

[0041] In an optional embodiment, when the electrode welding assembly 10 is short-circuited, that is, the welding wire 103 of the electrode welding assembly 10 contacts the welding point of the welding component 30, the first control component 101 detects that the welding wire 103 is in a short-circuited state, and the first control component 101 controls the welding wire fixing component 102 to start, and the welding wire fixing component 102 drives the welding wire 103 away from the welding point of the welding component 30. The first control component 101 transmits a synchronization signal to the second control component 201, and after the second control component 201 receives the synchronization signal, the second control component 201 controls the laser assembly to output energy normally.

[0042] In this embodiment, when the welding wire 103 is in a short-circuit state, the molten welding wire 103 drips the welding liquid onto the welding point of the welding part, and at this time, the second control component 201 controls the laser emitting component 202 to emit laser to heat the welding liquid dripping onto the welding point, thereby welding the welding point of the welding component 30. When the laser emitting component 202 emits laser to heat the welding liquid, the first control component 101 controls the welding wire 103 to be in low energy output or not to work, so as to avoid the welding wire 103 from arcing and causing the welding liquid to splash, causing the welding liquid to splash onto the lens of the laser emitting component 202, thereby reducing the efficiency of the laser emitting component 202 in transmitting the laser.

[0043] S13: If the short circuit of the electrode welding assembly 10 is ended, the first control component 101 controls the welding wire 103 of the electrode welding assembly 10 to be close to the welding point of the welding part 30, the first control component 101 controls the normal energy output of the electrode welding assembly 10, and transmits the synchronization signal to the second control component 201, and the second control component 201 controls the laser welding assembly 20 to have low energy output or not work.

[0044] In an optional embodiment, after the first control component 101 starts the welding wire fixing component 102 and the welding wire fixing component 102 drives the welding wire 103 away from the welding point of the welding component 30, the welding wire 103 is separated from the welding wire 103 of the welding component 30. The welding wire 103 is not in contact with the welding component 30, and the first control component 101 detects that the welding wire 103 is not in a short-circuit state. The first control component 101 controls the welding wire 103 to ignite an arc so that the welding wire 103 forms a molten state. When the welding wire 103 is molten, the first control component 101 transmits a synchronization signal to the second control component 201. After the second control component 201 detects the synchronization signal, the second control component 201 controls the laser welding assembly 20 to work with low energy output or normal energy output.

[0045] In this embodiment, when the first control element 101 controls the welding wire 103 to be in an arcing state, that is, when the welding wire 103 is away from the welding point position of the welding component 30, the second control element 201 receives the synchronization signal of the first control element 101, and the second control element 201 controls the laser emitting element 202 to output low energy or not work. That is, when the welding wire 103 is arcing, the laser emitting element 202 is output low energy or not work, thereby effectively avoiding the laser emitting element 202 emitting laser when the welding wire 103 is arcing, thereby causing the shielding gas to be disordered, and causing the arc to fluctuate when the welding wire 103 is arcing, so that the melting efficiency of the welding wire 103 is reduced.

[0046] In an optional embodiment, after the first control component 101 obtains that the short circuit of the electrode welding assembly 10 ends, that is, the welding wire 103 is separated from the welding point of the welding component 30, the first control component 101 controls the welding wire 103 to start arcing. When the welding wire 103 starts to arc, in order to improve the melting effect of the welding wire 103, after the first control component 101 detects that the short circuit of the welding wire 103 ends, the first control component 101 can control the welding wire fixing component 102 to continue to retract the welding wire 103, and the welding wire 103 continues to move in the direction away from the welding point of the welding component 30, that is, after the welding wire is separated from the welding point of the welding component 30, the welding wire fixing component 30 can control the welding wire 103 to be retracted for a specific time or a specific distance, thereby improving the melting effect of the welding wire 103.

[0047] In a specific application scenario, after the electrode welding assembly 10 is short-circuited, that is, after the welding wire 103 is separated from the welding point of the welding component 30, the first control component 101 controls the welding wire fixing component 102 to continue to retract 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 send the welding wire back, that is, the welding wire fixing component 102 controls the welding wire 103 to move toward the welding point close to the welding component 30. After the electrode welding assembly 10 is short-circuited, the melting effect of the welding wire 103 needs to be ensured during the time when the welding wire 103 is retracted to a specific distance or a specific time, and the time when the welding wire 103 is controlled to contact the welding point of the welding component 30. Among them, the retraction time and retraction distance of the welding wire 103 can be set according to the output power of the electrode welding assembly 10, and it is sufficient to ensure that the welding wire 103 melts into welding liquid and the welding liquid does not drip on other places. This application does not make specific limitations here.

[0048] In the above manner, when the first control component 101 controls the welding wire 103 to work, the second control component 201 controls the laser emitting component 202 to output low energy or not work, thereby avoiding the laser emitting component 202 emitting laser to cause the shielding gas to be disordered, and avoiding affecting the arcing of the welding wire 103, thereby reducing the melting efficiency of the welding wire 103. When the second control component 201 controls the laser emitting component 202 to emit laser, the first control component 101 controls the welding wire 103 to output low energy or not work, thereby avoiding the welding liquid splashing onto the lens of the laser emitting component 202 when the welding wire 103 is arcing and melting, causing the output efficiency of the laser emitting component 202 to be reduced when emitting laser.

[0049] The frequency at which the welding wire fixing part 102 drives the welding wire 103 to approach or move away from the welding spot is 70 Hz to 200 Hz, which can be set according to the actual welding needs, and this application does not make specific restrictions here. That is, by controlling the high-frequency reciprocating movement of the welding wire 103 by the first control part 101, when the first control part 101 controls the welding wire 103 to move away from the welding spot of the welding component 30, the second control part 201 can control the laser emitting part 202 to emit laser, thereby avoiding the situation that the welding liquid of the welding spot cools down during the period when the welding wire 103 has low energy output or is not working, and effectively improving the welding effect of the welding component 30.

[0050] Please refer to Figure 4 , Figure 4 yes Figure 3 Specifically, the above S11 may further include the following steps:

[0051] S111: The first control component 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.

[0052] In an optional embodiment, a collection module (not shown) may be provided in the first control component 101, and the collection module may collect the arc current of the welding wire 103, thereby determining whether the electrode welding assembly 10 is short-circuited based on the arc current collected by the collection module.

[0053] In this embodiment, when the acquisition module acquires that the welding wire 103 of the electrode welding assembly 10 has no current, the first control component 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 welding point of the welding component 30. When the acquisition module acquires that the welding wire 103 of the electrode welding assembly 10 has current, the first control component 101 ends the short position and the welding wire 103 of the electrode welding assembly 10 is in an arcing state, that is, the first control component 101 controls the welding wire 103 to arc and melt.

[0054] S112 : The power setting module 40 collects the average power of the electrode welding assembly 10 and the laser welding assembly 20 .

[0055] In an optional embodiment, when the first control component 101 and the second control component 201 respectively control the welding wire 103 and the laser emitting component 202 to work, the acquisition module collects the power of the electrode welding assembly 10 and the laser welding assembly 20, and after the power of the electrode welding assembly 10 and the laser welding assembly 20 is outputted normally, the collected power is calculated to obtain the average power of the electrode welding assembly 10 and the laser welding assembly 20 during normal energy output.

[0056] In other embodiments, the power setting module 40 collects the arcing power of the electrode welding assembly 10 and the laser emitting power of the laser welding assembly 20. The arcing power of the welding wire 103 and the laser emitting power of the laser welding assembly 20 can be collected through the collection module.

[0057] S113: The average power is transmitted to the first control component 101 and the second control component 201 respectively, so as to control the instantaneous power of the welding wire 103 and the laser emitting component 202 respectively.

[0058] In an optional embodiment, after the power setting module 40 collects the power of the arcing of the welding wire 103 of the electrode welding assembly 10 and the laser emitting element 202 emitting the laser, the average power of the electrode welding assembly 10 and the laser welding assembly 20 when working is calculated. After the average power is obtained, the instantaneous power of the arcing of the electrode welding assembly 10 is controlled by the first control element 101, and the instantaneous power of the transmission of the laser emitting element 202 emitting the laser is controlled by the second control element 201.

[0059] In a specific application scenario, the power setting module 40 collects the power of the welding wire 103 of the electrode welding assembly 10 when arcing, and calculates the first average power of the welding wire 103 when arcing. The power setting module 40 collects the power of the laser welding assembly 20 emitting the laser, and calculates the second average power of the laser emitting element 202 emitting the laser. When the first control element 101 controls the welding wire 103 to arc, the collection module transmits the calculated first average power to the first control element 101, and the first control element 101 receives the first average power and controls the welding wire 103 to arc at the first average power. When the second control element 201 controls the laser emitting element 202 to emit the laser, the collection module transmits the calculated second average power to the second control element 201, and the second control element 201 receives the second average power and controls the laser emitting element 202 to emit the laser at the second average power.

[0060] S114: The wire feeding speed setting module 50 collects the average wire feeding speed of the welding wire 103 .

[0061] In this embodiment, when the first control component 101 controls the electrode welding assembly 10 to start working, that is, the welding wire 103 outputs normal power, the wire feeding speed setting module 50 collects the wire feeding speed of the welding wire fixing component 102, that is, the moving speed of the welding wire 103, and the wire feeding speed setting module calculates the average speed of the movement of the welding wire 103.

[0062] S115: The average wire feeding speed is transmitted to the first control component 101, and the first control component 101 controls the instantaneous speed at which the welding wire 103 is driven by the welding wire fixing component 102 to move.

[0063] In this embodiment, after the wire feeding speed setting module 50 calculates the average speed of the welding wire 103 when it moves, the average speed is transmitted to the first control component 101. The first control component obtains the average wire feeding speed and controls the operating speed of the welding wire fixing component 102, so that the welding wire fixing component 102 drives the welding wire 103 to move at the average wire feeding speed.

[0064] Among them, the power setting module 40 and the wire feeding speed setting module 50 can collect data at the same time, or the speed of the welding wire 103 can be collected first by the wire feeding speed setting module 50, and then the output power of the electrode welding assembly 10 and the laser welding assembly 20 can be collected by the power setting module 40. This application does not make specific limitations here.

[0065] Please refer to Figure 5 , Figure 5 yes Figure 3 Specifically, the above S12 may further include the following steps:

[0066] S121: The first control component 101 controls the welding wire fixing component 102 to drive the welding wire 103 away from the welding point.

[0067] In an optional embodiment, the electrode welding assembly 10 is short-circuited, that is, the welding wire 103 abuts against the welding spot of the welding component 30, the welding wire 103 of the electrode welding assembly 10 has low energy output or does not work, and the first control component 101 drives the welding wire fixing component 102 to drive the welding wire 103 away from the welding spot of the welding component 30. After the first control component 101 drives the welding wire fixing component 102 to drive the welding wire 103 away from the welding spot of the welding component 30, the first control component 101 can control the welding wire 103 to ignite an arc.

[0068] S122: The first control component 101 transmits the synchronization signal to the second control component 201, and the second control component 201 controls the laser emitting component 202 to emit laser.

[0069] When the welding wire 103 of the electrode welding assembly 10 contacts the welding point of the welding component 30, the first control component 101 controls the welding wire 103 to output low energy or not work. The first control component 101 transmits the synchronization signal from the first control component 101 to the second control component 201 in real time. After the second control component 201 receives the synchronization signal transmitted by the first control component 101, the second control component 201 controls the laser emitting component 202 to emit laser.

[0070] In this embodiment, when the electrode welding assembly 10 is short-circuited, the first control component 101 controls the welding wire 103 to have low energy output or not to work, and controls the laser emitting component 202 to emit laser through the second control component 201, so as to heat the melted welding liquid of the welding wire 103 and prevent the welding liquid from cooling down.

[0071] Please refer to Figure 6 , Figure 6 yes Figure 3 Specifically, the above S13 may further include the following steps:

[0072] S131: The first control component 101 controls the welding wire fixing component 102 to drive the welding wire 103 to approach the welding point.

[0073] In this embodiment, when the electrode welding assembly 10 outputs energy normally, that is, the welding wire 103 is away from the welding point of the welding component 30, the first control component 101 controls the welding wire fixing component 102 to drive the welding wire 103 close to the welding point of the welding component 30. When the welding wire 103 is separated from the welding point of the welding component 30, the power setting module 40 transmits the calculated average power to the first control component 101, and the first control component 101 controls the output of the average power. After the first control component 101 controls the welding wire 103 to melt to form a molten welding liquid, the first control component 101 drives the welding wire fixing component 102 to drive the welding wire 103 close to the welding point position of the welding component 30.

[0074] S132: The first control component 101 transmits a synchronization signal to the second control component 201, and the second control component 201 controls the laser emitting component 202 to output low energy or not work.

[0075] In this embodiment, when the first control component 101 controls the arcing of the welding wire 103, that is, when the welding wire 103 is in a molten state, the first control component 101 transmits a synchronization signal to the second control component 201, and the second control component 201 controls the laser emitting component 202 to work or not work at a low energy output. During the period when the first control component 101 controls the arcing of the welding wire 103 and the welding wire 103 does not contact the welding point of the welding component 30, the second control component 201 controls the laser emitting component 202 to output at a low energy or not work, so as to prevent the laser emitting component 202 from emitting laser light to affect the transmission efficiency of the electrode welding assembly 10 and cause the shielding gas to be turbulent.

[0076] In other embodiments, when the first control component 101 controls the arcing of the welding wire 103, the arc length of the arcing of the welding wire 103 can be specifically controlled by an arc length control module (not shown) so that when the welding wire 103 is far away from the welding point, the arc length of the arcing will not contact the welding point of the welding component 30, thereby causing the short circuit time to be too long and the arcing time to be too short, resulting in poor melting effect of the welding wire 103 during operation. When the welding wire 103 subsequently contacts the welding point of the welding component 30, the welding liquid has a poor adhesion effect with the welding component 30, thereby causing the welding liquid to drip on the area outside the welding point of the welding component 30. This avoids the occurrence of poor welding effect.

[0077] In a specific application scenario, when the hybrid 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 outputs normal energy, the laser welding assembly 20 outputs low energy or does not work. On the contrary, when the electrode welding assembly 10 outputs low energy or does not work, the laser welding assembly 20 outputs normal energy. And the working process of the electrode welding assembly 10 is: arcing-short circuit-arcing cycle. In the arcing stage, an 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, and a molten droplet is gradually formed at the end of the welding wire 103. At this time, the first control component 101 controls the welding wire fixing component 102 to work, and the welding wire fixing component 102 drives the welding wire 103 to gradually approach the welding point on the welding component 30. The molten droplet falls on the welding point to form a molten pool to weld the welding component 30. In this process, the laser welding assembly 20 outputs low energy or does not work. After the welding wire 103 contacts the welding spot of the welding component 30, the electrode welding assembly 10 is in a short-circuit state. At this time, the electrode welding assembly has low energy output or does not work. The first control component 101 transmits a synchronization signal to the second control component 201, and the second control component 201 controls the laser emitting component 202 to emit a laser to heat the molten pool. After the welding wire 103 contacts the welding spot of the welding component 30 and drops the molten droplets on the welding spot, the welding wire fixing component 102 controls the welding wire 103 to move away from the welding spot of the welding component 30. At this time, the short circuit ends and the electrode welding assembly 10 starts to work again, that is, the welding wire 103 starts to ignite an arc. Repeat the above steps until the welding of the welding component 30 is completed, and the electrode welding assembly 10 and the laser welding assembly 20 both have low energy output or do not work.

[0078] Through the above-mentioned manner, the first control component 101 and the second control component 201 communicate in real time through the synchronization signal, so that when the electrode welding component 10 is working, the laser welding component 20 can output low energy or not work, and when the laser welding component 20 is working, the electrode welding component 10 can output low energy or not work, so that when the laser welding component 20 and the electrode welding component 10 are welded together, the welding liquid is prevented from splashing onto the lens of the laser emitting component 202, causing the laser emitting component 202 to emit laser efficiency to decrease, and affecting the melting efficiency of the welding wire 103 when the welding wire 103 is arcing and causing the shielding gas to be disordered, thereby effectively improving the efficiency and quality of welding.
