In wire drawing welding, forward wire feeding and reverse wire drawing alternate to achieve the effect of alternating short-circuit welding and arc welding stages. If the actual output value of the welding voltage can remain consistent with the set value throughout the process, the welding quality and efficiency can be guaranteed.

[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0036] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0037] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0038] To facilitate understanding, the application scenarios of the technical solution in this application will be introduced first.

[0039] With the development of welding technology and the advancement of automatic welding equipment, users have increasingly higher requirements for welding quality and efficiency.

[0040] Wire-drawing welding is a commonly used short-circuit welding technique. In wire-drawing welding, positive wire feeding (also called positive wire exit, wire feeding, or wire exit) and negative wire drawing (also called wire drawing) are alternated to achieve the effect of alternating short-circuit welding (also called short-circuit stage) and arc welding (also called arc stage). During wire-drawing welding, if the actual output value of the welding voltage can remain consistent with the set value, the welding quality and efficiency can be guaranteed. Therefore, how to ensure that the actual output value of the welding voltage remains consistent with the set value in wire-drawing welding has become a technical problem that urgently needs to be solved by those skilled in the art.

[0041] The welding voltage can also be called the arc voltage. Optionally, the voltage between the two voltage output terminals of the welding equipment can be used as the welding voltage. Alternatively, the voltage across the welding arc can also be used as the welding voltage. Both the actual output value and the set value of the welding voltage are average values ​​of the welding voltage over a certain period of time, which can be set according to the requirements of the actual application scenario. In other words, the actual output value of the welding voltage refers to the average value of the welding voltage actually output within that period. The set value of the welding voltage is an expected value, used to indicate the expected average value of the welding voltage within that period. Typically, the set value of the welding voltage is obtained by the user inputting it into the welding equipment.

[0042] Through practical application and research, the inventors discovered that to ensure the actual output value of the welding voltage in wire drawing welding remains consistent with the set value, a standard welding state (also called a standard state) that conforms to the actual welding scenario and the required welding voltage can be predetermined before welding. For this standard state, a standard setting value for the welding voltage and some other welding parameters can be set. Then, during actual welding, the welding parameters are output according to these standard setting values, ensuring that the actual output value of the welding voltage in wire drawing welding remains consistent with the standard setting value.

[0043] It should be noted that in different welding scenarios, the standard settings for the same welding parameters under standard conditions can be the same or different. Optionally, standard settings for welding parameters under different standard conditions can be preset, and then these preset standard settings can be stored together in the welding equipment or a storage device connected to the welding equipment. Later, during actual welding, the user can select the desired standard settings for welding parameters under the required standard conditions on the welding equipment's control panel. The welding equipment can then retrieve the corresponding standard settings for welding parameters under the specified standard conditions from the welding equipment itself or the storage device connected to the welding equipment.

[0044] Optionally, the user can select the standard setting value of the welding current under the required standard state on the operation panel of the welding equipment. After receiving the user's selection operation, the welding equipment can obtain the standard setting values ​​of other welding parameters corresponding to the standard setting value of the welding current from the welding equipment or the storage device connected to the welding equipment, such as the standard setting value of the welding voltage.

[0045] For example, such as Figure 1 As shown, the standard settings for the pre-set welding parameters may include T1, T2, S1, and S2.

[0046] Where T1 represents the standard setting value of the wire feeding delay time after short circuit detection. That is to say, when performing wire drawing welding according to the standard conditions, after short circuit detection, the wire feed will continue to be positive for T1 time until the end of T1 time, at which point it will switch to negative wire drawing.

[0047] T2 represents the standard setting value for the wire-pulling delay time after arc detection. In other words, when performing wire-pulling welding according to standard conditions, after arc detection, the wire-pulling will continue in the negative direction for the duration of T2 until the end of T2, at which point it will switch to the positive direction.

[0048] S1 represents the forward wire feed speed, or wire feed rate. That is, when performing wire drawing welding according to standard conditions, the wire is fed forward at the wire feed speed of S1.

[0049] S2 represents the negative wire drawing speed, or it can also be called the wire drawing speed. That is to say, when performing wire drawing welding according to the standard conditions, the wire is drawn in the negative direction according to the wire drawing speed of S2.

[0050] It should be noted that, for standard conditions, the pre-set standard values ​​of welding parameters may also include standard values ​​of other welding parameters besides those mentioned above, and this application does not impose any restrictions on this.

[0051] In actual wire drawing welding, outputting welding parameters according to the standard settings of the above welding parameters can ensure that the actual output value of the welding voltage is consistent with the standard setting value of the welding voltage.

[0052] However, in the actual wire drawing welding process, it may be necessary to change the welding voltage setting value according to specific welding requirements. That is, the actual welding voltage setting value differs from the standard welding voltage setting value, resulting in a deviation. Optionally, the actual welding voltage setting value may be greater than the standard welding voltage setting value. Optionally, the actual welding voltage setting value may also be less than the standard welding voltage setting value.

[0053] When there is a deviation between the actual set value of the welding voltage and the standard set value of the welding voltage, if the welding parameters are still output according to the standard set value of the welding parameters, the actual output value of the welding voltage will not be consistent with the actual set value of the welding voltage.

[0054] To ensure that the actual output value of the welding voltage remains consistent with the actual set value even when there is a deviation between the actual set value and the standard set value, this application provides a voltage control method and apparatus for wire drawing welding. This method allows the controller to obtain the actual set value of the welding voltage during wire drawing welding. When a deviation exists between the actual set value and the standard set value, the controller can adjust the output value of the first preset welding parameter based on the standard set value during the subsequent wire drawing welding process. Then, the controller outputs the first preset welding parameter according to the adjusted output value, thereby ensuring that the actual output value of the welding voltage remains consistent with the actual set value. This guarantees the welding quality and efficiency of wire drawing welding and improves its applicability.

[0055] The voltage control method for wire drawing welding provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0056] See Figure 2 , Figure 2 This is a schematic flowchart illustrating a voltage control method for wire drawing welding, provided as an embodiment of this application. This method can be applied to terminal equipment or a controller installed in a welding system. The following description uses a controller installed in a welding system (hereinafter referred to as the controller) as an example to illustrate an embodiment of this application. Figure 2 As shown, the method may include the following steps:

[0057] Step S101: Obtain the actual set value of the welding voltage in wire drawing welding.

[0058] Optionally, for more precise control, the controller can acquire the actual set value of the welding voltage in real time during wire drawing welding.

[0059] Optionally, in applications where accuracy requirements are relatively low, the controller can also periodically or periodically acquire the actual set value of the welding voltage during wire drawing welding according to a preset cycle.

[0060] Optionally, when the controller receives an input operation from a user that triggers a function button or control to input a set value for the welding voltage, it can determine the set value of the welding voltage input by the user as the actual set value of the welding voltage, thereby obtaining the actual set value of the welding voltage in wire drawing welding.

[0061] It should be understood that the controller can also obtain the actual set value of the welding voltage in wire drawing welding under other triggering conditions, and this application does not limit this.

[0062] It should be noted that once the controller obtains the actual set value of the welding voltage in wire drawing welding using any method, the subsequent control of the welding voltage is implemented in the same way. Therefore, this application uses the acquisition of the actual set value of the welding voltage in wire drawing welding in any single instance as an example to illustrate the voltage control method for wire drawing welding in this application.

[0063] Step S102: If there is a deviation between the actual set value of the welding voltage and the standard set value of the welding voltage, in the subsequent wire drawing welding process, the output value of the first preset welding parameter is adjusted based on the standard set value of the first preset welding parameter.

[0064] In actual welding, as the welding scenario changes, it may be necessary to increase the welding energy. In this case, the user can input an actual setting value that is greater than the standard setting value of the welding voltage through the function button or control of the welding voltage setting value on the welding equipment. This will cause the controller to control the welding equipment to output according to the actual setting value, thereby increasing the welding energy.

[0065] Optionally, the welding voltage output can be increased by reducing the duration of the short-circuit welding phase. Alternatively, the welding voltage output can be increased by increasing the duration of the arc welding phase. Alternatively, the welding voltage output can be increased by increasing the welding current. Alternatively, the welding voltage output can be increased by simultaneously reducing the duration of the short-circuit welding phase and increasing the duration of the arc welding phase. Alternatively, the welding voltage output can be increased by simultaneously reducing the duration of the short-circuit welding phase and increasing the welding current. Alternatively, the welding voltage output can be increased by simultaneously reducing the duration of the short-circuit welding phase, increasing the duration of the arc welding phase, and increasing the welding current.

[0066] Conversely, as the welding scenario changes, it may be necessary to reduce the welding energy. In this case, the user can input an actual setting value that is lower than the standard setting value of the welding voltage through the function button or control of the welding voltage setting value. This will cause the controller to control the welding equipment to output according to the actual setting value, thereby reducing the welding energy.

[0067] Optionally, the welding voltage output can be reduced by increasing the duration of the short-circuit welding phase. Alternatively, the welding voltage output can be reduced by decreasing the duration of the arc welding phase. Alternatively, the welding voltage output can be reduced by decreasing the welding current. Alternatively, the welding voltage output can be reduced by simultaneously increasing the duration of the short-circuit welding phase and decreasing the duration of the arc welding phase. Alternatively, the welding voltage output can be reduced by simultaneously increasing the duration of the short-circuit welding phase and decreasing the welding current. Alternatively, the welding voltage output can be reduced by simultaneously increasing the duration of the short-circuit welding phase, decreasing the duration of the arc welding phase, and decreasing the welding current.

[0068] Based on this, the first preset welding parameters may include one or more of a first duration, a second duration, and welding current. The first duration refers to the duration of a short-circuit welding phase in wire drawing welding. The second duration refers to the duration of an arc welding phase in wire drawing welding.

[0069] Then, in one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can reduce the output value for the first duration based on the standard set value for the first duration.

[0070] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, the controller can increase the output value of the second duration based on the standard set value of the second duration during the subsequent wire drawing welding process.

[0071] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, the controller can increase the output value of the welding current based on the standard set value of the welding current during the subsequent wire drawing welding process.

[0072] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can reduce the output value for the first duration and increase the output value for the second duration, respectively, based on the standard set values ​​for the first duration and the second duration.

[0073] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can reduce the output value of the first duration and increase the output value of the welding current based on the standard set values ​​of the first duration and the welding current, respectively.

[0074] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can increase the output value of the second duration and the output value of the welding current based on the standard set values ​​of the second duration and the welding current, respectively.

[0075] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can, based on the standard set values ​​of the first duration, the second duration, and the welding current, respectively, reduce the output value of the first duration, increase the output value of the second duration, and increase the output value of the welding current.

[0076] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, the controller can increase the output value for the first duration based on the standard set value for the first duration during the subsequent wire drawing welding process.

[0077] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, the controller can reduce the output value of the second duration based on the standard set value of the second duration during the subsequent wire drawing welding process.

[0078] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, the controller can reduce the output value of the welding current based on the standard set value of the welding current during the subsequent wire drawing welding process.

[0079] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can increase the output value for the first duration and decrease the output value for the second duration, respectively, based on the standard set values ​​for the first duration and the second duration.

[0080] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can increase the output value of the first duration and decrease the output value of the welding current based on the standard set values ​​of the first duration and the welding current, respectively.

[0081] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can reduce the output value of the second duration and the output value of the welding current based on the standard set values ​​of the second duration and the welding current, respectively.

[0082] In one possible implementation, after the controller obtains the actual set value of the welding voltage, if the actual set value of the welding voltage is less than the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can increase the output value of the first duration, decrease the output value of the second duration, and decrease the output value of the welding current based on the standard set values ​​of the first duration, the second duration, and the welding current, respectively.

[0083] It should be noted that in the different implementation methods mentioned above, the magnitude of the increase or decrease of the same first preset parameter is different, and the specific setting can be made according to the needs of the actual welding scenario.

[0084] Furthermore, during wire drawing welding, if the wire feed delay time after short circuit detection is reduced, the length of the welding wire fed into the molten pool can be reduced, thus shortening the duration of the short-circuit welding phase. Alternatively, increasing the negative wire drawing speed after short circuit detection—that is, increasing the speed of wire retraction and performing negative wire drawing more quickly—can also shorten the duration of the short-circuit welding phase. Or, reducing the wire feed delay time after short circuit detection while simultaneously increasing the negative wire drawing speed can also shorten the duration of the short-circuit welding phase. It should be understood that the magnitude of the increase or decrease in the corresponding parameters will differ depending on the method used.

[0085] Furthermore, in the wire drawing welding process, if the wire drawing delay time after arc detection is increased, the wire retraction height can be increased, thereby increasing the arc length and the duration of the arc welding phase. Alternatively, after arc detection, the wire feed speed can be reduced, i.e., the forward wire feed is performed more slowly, which can also increase the duration of the arc welding phase. Or, after arc detection, increasing the wire drawing delay time while reducing the wire feed speed can also increase the duration of the arc welding phase. It should be understood that the magnitude of the increase or decrease in the corresponding parameters will differ depending on the method used.

[0086] Furthermore, during the wire drawing welding process, increasing the peak current in the short-circuit welding stage can increase the welding current. Alternatively, increasing the peak current in the arc welding stage can also increase the welding current. Or, increasing the base current in the arc welding stage can also increase the welding current. Alternatively, increasing both the peak and base currents in the arc welding stage can also increase the welding current. It should be understood that the magnitude of the increase or decrease in the corresponding parameters will differ depending on the method used.

[0087] Conversely, in wire drawing welding, increasing the wire feed delay after short circuit detection can increase the length of the welding wire fed into the molten pool, thus increasing the duration of the short circuit welding phase. Alternatively, decreasing the negative wire drawing speed after short circuit detection—that is, reducing the wire retraction speed and performing negative wire drawing more slowly—can also increase the duration of the short circuit welding phase. Or, increasing the wire feed delay after short circuit detection while simultaneously decreasing the negative wire drawing speed can also increase the duration of the short circuit welding phase. It should be understood that the magnitude of the increase or decrease in the corresponding parameters will differ depending on the method used.

[0088] Furthermore, in the wire drawing welding process, if the wire drawing delay time after arc detection is reduced, the wire retraction height can be reduced, thereby reducing the arc length and the duration of the arc welding phase. Alternatively, increasing the wire feed speed after arc detection, i.e., faster forward wire feeding, can also reduce the duration of the arc welding phase. Or, reducing the wire drawing delay time after arc detection while simultaneously increasing the wire feed speed can also reduce the duration of the arc welding phase. It should be understood that the magnitude of the increase or decrease in the corresponding parameters will differ depending on the method used.

[0089] Furthermore, during wire drawing welding, reducing the peak current in the short-circuit welding stage can reduce the welding current. Alternatively, reducing the peak current in the arc welding stage can also reduce the welding current. Alternatively, reducing the base current in the arc welding stage can also reduce the welding current. Alternatively, reducing both the peak and base currents in the arc welding stage can also reduce the welding current. It should be understood that the reduction in the corresponding parameters will vary depending on the method used.

[0090] In other words, the controller can adjust the output value of the first preset welding parameter by adjusting the output value of the second preset welding parameter. For example, the second preset welding parameter may include one or more of the following: wire feeding delay time after short circuit detection, negative wire drawing speed, wire drawing delay time after arc detection, wire feeding speed, peak current during short circuit welding, peak current during arc welding, and base current during arc welding.

[0091] Based on this, in one possible implementation, when the actual set value of the welding voltage is greater than the standard set value of the welding voltage, during the subsequent wire drawing welding process, the controller can adjust the output value of the first preset welding parameter according to one or more of the following methods:

[0092] The first method: After short circuit detection, reduce the wire feeding delay time after short circuit detection based on the standard setting value to reduce the output value of the first time.

[0093] The second method: After short circuit detection, increase the wire drawing speed based on the standard setting value to reduce the output value of the first duration.

[0094] The third method: After arc detection, the wire-drawing delay time after arc detection is increased based on the standard setting value to increase the output value of the second time.

[0095] The fourth method: After arc detection, reduce the wire feeding speed after arc detection based on the standard setting value to increase the output value of the second duration.

[0096] The fifth method is to increase the peak current during the short-circuit welding stage to increase the output value of the welding current in wire drawing welding.

[0097] The sixth method is to increase the peak current during the arc welding stage to increase the output value of the welding current in wire drawing welding.

[0098] The seventh method is to increase the base current during the arc welding stage to increase the output value of the welding current in the pull-out welding.

[0099] It should be noted that when adjusting the output value of each second preset welding parameter according to one or more of the first to seventh methods described above, the adjustment range of the same second preset welding parameter is different in different embodiments (i.e., different combinations of the first to seventh methods described above).

[0100] In one possible implementation, when the actual set value of the welding voltage is less than the standard set value of the welding voltage, during the subsequent wire drawing welding process, the controller can adjust the output value of the first preset welding parameter in one or more of the following ways:

[0101] The eighth method: After short circuit detection, the wire feeding delay time after short circuit detection is increased based on the standard setting value to increase the output value of the first time.

[0102] The ninth method: After short circuit detection, reduce the wire drawing speed based on the standard setting value to increase the output value of the first duration.

[0103] The tenth method: After arc detection, reduce the wire-drawing delay time after arc detection based on the standard setting value to reduce the output value of the second time.

[0104] Eleventh method: After arc detection, increase the wire feeding speed after arc detection based on the standard setting value to reduce the output value of the second duration.

[0105] The twelfth method: reduce the peak current during the short-circuit welding stage to reduce the output value of the welding current in wire drawing welding.

[0106] The thirteenth method: reduce the peak current during the arc welding stage to reduce the output value of the welding current in wire drawing welding.

[0107] The fourteenth method: reduce the base current during the arc welding stage to reduce the output value of the welding current in pull-out welding.

[0108] It should be noted that when adjusting the output value of each second preset welding parameter according to one or more of the eighth to fourteenth methods described above, the adjustment range of the same second preset welding parameter is different in different embodiments (i.e., different combinations of the eighth to fourteenth methods described above).

[0109] The specific implementation process of step S102 will be illustrated below with reference to the accompanying drawings.

[0110] like Figure 3 As shown, when an increase in voltage is required, i.e., when the actual set value of the welding voltage is greater than the standard set value, after arc detection, the controller can increase the wire-drawing delay time after arc detection by ΔT2 based on the standard set value T2; decrease the wire feed speed by ΔS1 based on the standard set value S1; increase the peak current of the arc welding stage by ΔIP1 based on the standard set value IP; and increase the base current of the arc welding stage by ΔIB1 based on the standard set value IB. After short-circuit detection, the controller can decrease the wire feed delay time after short-circuit detection by ΔT1 based on the standard set value T1; increase the wire-drawing speed after short-circuit detection by ΔS2 based on the standard set value S2; and increase the peak current of the short-circuit welding stage by ΔIA1 based on the standard set value IA. The specific values ​​of ΔT2, ΔS1, ΔIP1, ΔIB1, ΔT1, ΔS2, and ΔIA1 can be set according to the requirements of the actual welding scenario. The values ​​of ΔT2, ΔS1, ΔIP1, ΔIB1, ΔT1, ΔS2, and ΔIA1 are usually different in different welding scenarios.

[0111] like Figure 4 As shown, when it is necessary to reduce or decrease the voltage, i.e., when the actual set value of the welding voltage is less than the standard set value, after arc detection, the controller can reduce the wire-drawing delay time after arc detection by ΔT4 based on the standard set value T2; increase the wire feed speed by ΔS3 based on the standard set value S1; reduce the peak current of the arc welding stage by ΔIP2 based on the standard set value IP; and reduce the base current of the arc welding stage by ΔIB2 based on the standard set value IB. After short-circuit detection, the controller can increase the wire feed delay time after short-circuit detection by ΔT3 based on the standard set value T1; reduce the wire-drawing speed after short-circuit detection by ΔS4 based on the standard set value S2; and reduce the peak current of the short-circuit welding stage by ΔIA2 based on the standard set value IA. The specific values ​​of ΔT4, ΔS3, ΔIP2, ΔIB2, ΔT3, ΔS4, and ΔIA2 can be set according to the requirements of the actual welding scenario. The values ​​of ΔT4, ΔS3, ΔIP2, ΔIB2, ΔT3, ΔS4, and ΔIA2 are usually different in different welding scenarios.

[0112] Step S103: Output the first preset welding parameters according to the adjusted output value of the first preset welding parameters, so that the actual output value of the welding voltage is the same as the actual set value of the welding voltage.

[0113] According to any embodiment of step S102, after adjusting the output value of the first preset welding parameter and outputting according to the corresponding adjusted welding parameter, the actual output value of the welding voltage can be the same as the actual set value of the welding voltage.

[0114] For example, such as Figure 3 As shown, when the voltage needs to be increased, the controller obtains the actual set value of the welding voltage in the wire drawing welding process. When it is determined that the actual set value of the welding voltage is greater than the standard set value of the welding voltage, in the subsequent wire drawing welding process, after arc detection, the wire drawing continues for a duration of T2+ΔT2, and then the wire is fed at a speed of S1-ΔS1. The peak current of the arc welding stage is output according to IP+ΔIP1, and the base current of the arc welding stage is output according to IB+ΔIB1. After short circuit detection, the wire feeding continues for a duration of T1-ΔT1, and then the wire drawing is performed at a speed of S2+ΔS2. The peak current of the short circuit welding stage is output according to IA+ΔIA1.

[0115] For example, such as Figure 4 As shown, when it is necessary to reduce or decrease the voltage, the controller obtains the actual set value of the welding voltage in the wire drawing welding process. When it determines that the actual set value of the welding voltage is less than the standard set value of the welding voltage, in the subsequent wire drawing welding process, after arc detection, the wire drawing continues for a duration of T2-ΔT4. Then, the wire is fed at a speed of S1+ΔS3, and the peak current of the arc welding stage is output according to IP-ΔIP2, and the base current of the arc welding stage is output according to IB-ΔIB2. After short circuit detection, the wire feeding continues for a duration of T1+ΔT3, and the wire drawing continues at a speed of S2-ΔS4. The peak current of the short circuit welding stage is output according to IA-ΔIA2.

[0116] Furthermore, when there is no deviation between the actual set value of the welding voltage and the standard set value of the welding voltage, that is, when the actual set value of the welding voltage is the same as the standard set value of the welding voltage, the controller can output the first preset welding parameters according to the standard set value of the first preset welding parameters, so that the welding equipment operates in the standard state, that is, in the standard state, wire drawing welding is performed. In this way, the actual output value of the welding voltage is consistent with the actual set value of the welding voltage.

[0117] It should be noted that, Figure 2The illustrated embodiment uses the example of the controller controlling the voltage after acquiring the actual set value of the welding voltage during wire drawing welding at any given time. Specifically, during wire drawing welding, the controller can acquire the actual set value of the welding voltage in real time, or periodically or periodically, or it can acquire the actual set value of the welding voltage under user-triggered conditions. Each time the actual set value of the welding voltage is acquired, it can be controlled according to... Figure 2 The embodiment shown controls the welding voltage so that the actual output value of the welding voltage is always consistent with the actual set value during the wire drawing welding process, thereby ensuring the welding quality and welding efficiency of the wire drawing welding.

[0118] In the voltage control method for wire drawing welding provided in this application embodiment, the controller can obtain the actual set value of the welding voltage during wire drawing welding. When there is a deviation between the actual set value of the welding voltage and the standard set value of the welding voltage, in the subsequent wire drawing welding process, the controller can adjust the output value of the first preset welding parameter based on the standard set value of the first preset welding parameter, and then output the first preset welding parameter according to the adjusted output value, so that the actual output value of the welding voltage is consistent with the actual set value of the welding voltage, thereby ensuring the welding quality and welding efficiency of wire drawing welding and improving applicability.
