[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0020] Referring to Figure 1 , Figure 1 A flowchart of a welding method provided by the embodiment of the present application is shown in the figure. The method can be applied to a control device, such as a controller, etc. As shown in Figure 1 , the method comprises the following steps:

[0021] Step S101, determining a welding mode based on a selection operation of a swing mode control by a user in a welding navigation interface.

[0022] In an optional implementation, a welding control application (application, APP) can be installed in the control device. The welding control APP can provide a login interface for the user. After receiving a login operation of the user in the login interface, the control device can display a welding navigation interface. The swing mode control is arranged on the welding navigation interface, and the user can select the welding mode by a selection operation of the swing mode control.

[0023] After the control device receives the selection operation of the swing mode control by the user in the welding navigation interface, the welding mode can be determined based on the selection operation in response to the selection operation. For example, the welding mode can be a vertical welding swing mode, a horizontal swing mode, an inclined swing mode, etc.

[0024] Step S102, if the welding mode is the vertical welding swing mode, displaying a parameter setting interface.

[0025] Based on the user's selection of the oscillation mode control, the control equipment determines that the welding method is vertical oscillation and then displays the parameter setting interface. This interface allows for the configuration of one or more controls, such as welding current and welding voltage controls. For example, see [link to relevant documentation]. Figure 2 , Figure 2 This is an example diagram of a parameter setting interface provided in an embodiment of this application.

[0026] Step S103: Based on the user's input operations on the welding current control and welding voltage control in the parameter setting interface, determine the first current, the second current, the third current, the first voltage, the second voltage, and the third voltage; the first current and the second current are both greater than the third current, and the first voltage and the second voltage are both greater than the third voltage.

[0027] Based on the user's input operations on the welding current and welding voltage controls in the parameter setting interface, the implementation methods of the first current, second current, third current, first voltage, second voltage, and third voltage are determined, and can include multiple methods. For example:

[0028] In the first implementation, the welding current control in the parameter setting interface can include a first current control, and the welding voltage control can include a first voltage control. Furthermore, linkage controls can also be set on the parameter setting interface. For example, still using... Figure 2 For example, Figure 2 The input control 201, which corresponds to both the letter A and the welding current, can be used as the first current control. Figure 2 The input control 202, which corresponds to both the letter A and the welding voltage, can be used as the first voltage control. Figure 2 The checkmark control 203 can be used as a linked control.

[0029] In this implementation, the control device can determine the first current based on the user's input to the first current control. Specifically, the control device can determine the first current based on the value input by the user in the first current control. Similarly, the control device can determine the first voltage based on the user's input to the first voltage control. Specifically, the control device can determine the first voltage based on the value input by the user in the first voltage control.

[0030] After the control device determines the first current and the first voltage, if it receives a user's check operation on the linkage control, in response to the check operation, the control device can determine the second current and the third current based on the first current and the preset current linkage strategy, and determine the second voltage and the third voltage based on the first voltage and the preset voltage linkage strategy.

[0031] The preset current linkage strategy can be as follows: the second current is the same as the first current, and the third current is 0.3 times the first current (or any value from 0.3 to 0.7). The preset voltage linkage strategy can be as follows: the second voltage is the same as the first voltage, and the third voltage is 0.3 times the first voltage (or any value from 0.3 to 0.7). Alternatively, the preset current linkage strategy can also be as follows: the second current is the same as the first current, and the third current is two-thirds (2 / 3) of the first current. The preset voltage linkage strategy can also be as follows: the second voltage is the same as the first voltage, and the third voltage is ninety percent (90%) of the first voltage.

[0032] For example, the first and second currents can both be set to 150A (Amperes), and the third current can be set to 100A (Amperes). The first and second voltages can both be set to 18.4V (Volts), and the third voltage can be set to 16.8V (Volts).

[0033] It should be noted that both the preset current linkage strategy and the preset voltage linkage strategy can be set to other linkage strategies according to the needs of the actual application scenario, and this application does not limit them.

[0034] In the second implementation, the control device may first receive the user's selection operation of the linkage control; then, based on the user's input operations on the first current control and the first voltage control respectively, determine the first current and the first voltage; then, based on the first current and the preset current linkage strategy, determine the second current and the third current, and based on the first voltage and the preset voltage linkage strategy, determine the second voltage and the third voltage.

[0035] In the third implementation, the welding current control in the parameter setting interface can also include a second current control and a third current control, and the welding voltage control can also include a second voltage control and a third voltage control. For example, still using... Figure 2 For example, Figure 2 The input control 204, which corresponds to both the letter B and the welding current, can be used as a second current control. Figure 2 The input control 205, which corresponds to both the letter C and the welding current, can be used as a third current control. Figure 2 The input control 206, which corresponds to both the letter B and the welding voltage, can be used as a second voltage control. Figure 2 The input control 207, which corresponds to both the letter C and the welding voltage, can be used as a third voltage control.

[0036] In this implementation, after the control device determines the second current, third current, second voltage, and third voltage using the first or second implementation method described above, it can update these parameters if it receives user input on the second current control, third current control, second voltage control, and / or third voltage control. That is, after receiving user input on one or more of the second current control, third current control, second voltage control, and third voltage control, the control device can update the current or voltage corresponding to those controls accordingly. Then, the control device will perform welding according to the updated current and voltage.

[0037] In the fourth implementation, the user can also choose not to check the linkage controls. In this implementation, after the control device determines that it has not received any operation to check the linkage controls, the control device can determine the first current, second current, third current, first voltage, second voltage, and third voltage based on the user's input operations on the first current control, second current control, third current control, first voltage control, second voltage control, and third voltage control.

[0038] Specifically, the control device can determine the value input by the user in the first current control as the first current. Similarly, the control device can determine the value input by the user in the second current control as the second current, the value input by the user in the third current control as the third current, the value input by the user in the first voltage control as the first voltage, the value input by the user in the second voltage control as the second voltage, and the value input by the user in the third voltage control as the third voltage.

[0039] Step S104: Output a first control signal and a second control signal to cause the oscillating device to drive the vertical welding device to oscillate based on the first control signal for oscillating welding; and, based on the second control signal, the power supply device switches the welding current and welding voltage during the oscillation of the vertical welding device; wherein, the welding current when the vertical welding device oscillates to the two ends is the first current and the second current, and the welding voltage is the first voltage and the second voltage, respectively; the welding current and welding voltage when the vertical welding device oscillates to the lowest point are the third current and the third voltage, respectively.

[0040] In one optional implementation, the parameter setting interface also includes an amplitude control. In this implementation, outputting a first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate based on the first control signal can be achieved as follows: determining the oscillation amplitude of the vertical welding equipment based on the user's input to the amplitude control in the parameter setting interface; generating a first control signal based on the amplitude; and outputting the first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate according to the amplitude based on the first control signal.

[0041] In other words, the oscillating device, based on the first control signal, drives the vertical welding equipment to oscillate. The amplitude of the oscillation is the amplitude input by the user through the amplitude control, which is the distance between the two endpoints (or the highest point) during the oscillation. For example, still using... Figure 2 For example, the amplitude of the oscillation of the vertical welding equipment driven by the oscillating device can be... Figure 3 The distance from end A to end B in the schematic diagram of the swing is shown in image 208. See also... Figure 3 , Figure 3 The distance m from endpoint A to endpoint B can be the amplitude of the vertical welding swing driven by the swinging device.

[0042] Optionally, the amplitude can be set to a value greater than or equal to the width of the weld bevel (also known as the weld bead, etc.).

[0043] In one optional implementation, a height control can also be set in the parameter setting interface. In this implementation, outputting a first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate based on the first control signal can also be implemented as follows: determining the oscillation height of the vertical welding equipment based on the user's input operation on the height control in the parameter setting interface; generating a first control signal based on the height; and outputting the first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate according to the height based on the first control signal.

[0044] In other words, the oscillating device, based on the first control signal, drives the vertical welding equipment to oscillate, and the oscillation height is the height input by the user through the height control. This height is the vertical distance from the root of the weld when the vertical welding equipment oscillates to its endpoint. For example, still using... Figure 3 For example, Figure 3 The vertical distance h from the B-end point to the root of the weld can be the height at which the oscillating device drives the vertical welding device to oscillate.

[0045] In one optional implementation, a time control can also be set in the parameter setting interface. In this implementation, outputting a first control signal to cause the oscillating device to drive the vertical welding device to oscillate based on the first control signal can also be implemented as follows: based on the user's input operation on the time control in the parameter setting interface, determine the duration for which the vertical welding device stays at the endpoint when it oscillates; generate a first control signal based on the duration; output the first control signal to cause the oscillating device to drive the vertical welding device to oscillate according to the duration based on the first control signal.

[0046] In other words, the oscillating device drives the vertical welding machine to oscillate based on the first control signal, and during oscillation, at each end point (e.g. Figure 2 The duration of the stay at endpoint A or endpoint B (as shown) can be the duration entered by the user through the time control.

[0047] In one optional implementation, the oscillating device drives the vertical welding device to oscillate based on a first control signal. This can also be achieved as follows: the oscillating device drives the vertical welding device based on the first control signal to oscillate along the direction of weld extension in a zigzag pattern. That is, the oscillating device, based on the first control signal, drives the vertical welding device to oscillate in a direction perpendicular to the direction of weld extension, and moves along the direction of weld extension in a zigzag pattern, thus oscillating along the direction of weld extension in a zigzag pattern. For example, still using... Figure 2 For example, Figure 2 The zigzag swing path is shown in both the schematic diagrams of the swing in images 208 and 209.

[0048] In one optional implementation, the parameter setting interface may further include one or more of the following controls: pitch control, speed control, and frequency control. In this implementation, outputting a first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate based on the first control signal can also be implemented as follows: based on user input to the pitch control, speed control, and / or frequency control in the parameter setting interface, determine the oscillation pitch, speed, and / or frequency of the vertical welding equipment; generate the first control signal based on the pitch, speed, and / or frequency; output the first control signal to cause the oscillating device to drive the vertical welding equipment to oscillate according to the pitch, speed, and / or frequency based on the first control signal.

[0049] In other words, the oscillating device drives the vertical welding equipment to oscillate based on the first control signal. The pitch, speed, and / or frequency during oscillation can be input by the user through pitch controls, speed controls, and / or frequency controls. When the vertical welding equipment oscillates along a zigzag path, the two end points can include multiple first end points and multiple second end points. Optionally, the process of the vertical welding equipment oscillating from one first end point to a directly opposite second end point, and then oscillating forward from that second end point to the next first end point, can be recorded as one oscillation cycle. For example, still using... Figure 2 For example, combined with Figure 2 The schematic diagram of the swinging part in image 208 shows that the process of the vertical welding equipment swinging from end point B1 to end point A1, and then swinging forward from end point A1 to end point B2, is recorded as one swinging cycle.

[0050] Therefore, pitch refers to the distance traveled by the vertical welding equipment during one oscillation cycle. For example, the pitch can be... Figure 4 The distance from endpoint B1 to endpoint B2. Speed ​​refers to the forward speed of the vertical welding equipment. Frequency refers to the oscillation frequency of the vertical welding equipment.

[0051] Optionally, the pitch, speed, and frequency can also be set according to the following formula: P = V / f. Here, P represents the pitch, V represents the speed, and f represents the frequency. For example, when two of the parameters are received from the user through the corresponding control, the other parameter can be determined according to the aforementioned formula.

[0052] In one alternative implementation, the power supply device switches the welding current and welding voltage based on a second control signal during the oscillation of the vertical welding equipment. This can be achieved as follows: the power supply device can linearly switch the welding current and welding voltage based on the second control signal during the oscillation of the vertical welding equipment.

[0053] In one optional implementation, the power supply device switches the welding current and welding voltage based on a second control signal during the oscillation of the vertical welding equipment. This can also be achieved as follows: Based on the second control signal, during the oscillation of the vertical welding equipment, when the equipment swings from the endpoint to the lowest point, the power supply device can switch the welding current and welding voltage to a third current and a third voltage when the equipment swings to one-quarter (1 / 4) of its amplitude. Similarly, when the equipment swings from the lowest point to the endpoint, the power supply device can switch the welding current and welding voltage to a first current or a second current, and the welding voltage to a first voltage or a second voltage, when the equipment swings to one-quarter of its amplitude.

[0054] It should be noted that the power supply equipment can switch the welding current and welding voltage during the swinging process of the vertical welding equipment based on the second control signal. Other methods can also be used, which will not be listed here.

[0055] In the welding method provided in this application embodiment, the control device can provide a welding navigation interface, and the welding mode can be determined according to the user's selection operation in the welding navigation interface. When the welding mode is vertical welding oscillation mode, the control device can also display a parameter setting interface. Then, the control device can determine the welding current and welding voltage corresponding to the two ends and the lowest point during the oscillation of the vertical welding equipment according to the welding current and welding voltage values ​​input by the user in the parameter setting interface, and the welding current corresponding to the two ends is higher than the welding current corresponding to the lowest point, and the welding voltage corresponding to the two ends is higher than the welding voltage corresponding to the lowest point. Afterwards, the control device can output a first control signal and a second control signal, thereby controlling the oscillation device to drive the vertical welding equipment to oscillate together through the first control signal. And, controlling the power supply device through the second control signal to switch the welding current and welding voltage during the oscillation of the vertical welding equipment, so that the welding current when the vertical welding equipment oscillates to the two ends is greater than the welding current when the vertical welding equipment oscillates to the lowest point, and the welding voltage when the vertical welding equipment oscillates to the two ends is greater than the welding voltage when the vertical welding equipment oscillates to the lowest point.

[0056] In this way, when the vertical welding equipment welds both sides of the weld, it can increase the heat input, resulting in better fusion on both sides of the vertical plate. When the vertical welding equipment swings to the middle position of the weld, the heat input can be appropriately reduced to prevent the weld pool from sagging. This leads to better weld formation and higher welding efficiency.

[0057] It is understood that the above embodiments are merely examples, and modifications can be made to the above embodiments in actual implementation. Those skilled in the art will understand that any modifications to the above embodiments that do not require creative effort fall within the protection scope of this application, and will not be described in detail in the embodiments.

[0058] Based on the same inventive concept, this application also provides a welding apparatus and a welding system. Since the principle of the welding apparatus and welding system in solving the problem is similar to that of the welding method, the implementation of the welding apparatus and welding system can refer to the implementation of the welding method, and the repeated parts will not be described again.
