Description

Technical Field

[0001] This application belongs to the field of welding technology, and in particular relates to a welding parameter setting method, apparatus and welding machine. Background Technology

[0002] Currently, in Gas Tungsten Arc Welding (GTAW) technology, the selection and adjustment of GTAW welding process parameters are typically achieved by the welding operator independently operating the human-machine interface (HMI) corresponding to each parameter on the welding machine's control panel. However, due to the wide variety of welding process parameters, and the fact that the welding operator needs to follow a specific sequence of steps when selecting, setting, and adjusting these parameters on the HMI, the parameter setting process is cumbersome and difficult, thus affecting welding efficiency. Summary of the Invention

[0003] In view of this, embodiments of this application provide a welding parameter setting method, apparatus and welding machine to solve the technical problem that the welding process parameter setting process in the existing GTAW process is relatively cumbersome and difficult, which affects the welding efficiency.

[0004] The first aspect of this application provides a welding parameter setting method applied to a welding machine. The welding machine has multiple pre-stored welding modes. In each welding mode, each welding parameter has parameter information corresponding to the welding mode. The method includes: responding to a first control operation to enter a first-level collaborative mode; selecting a target welding mode from the multiple welding modes; determining the parameter information of each welding parameter according to the target welding mode; responding to a second control operation to exit the first-level collaborative mode and enter a second-level collaborative mode; collaboratively adjusting the parameter information of the target parameter among the welding parameters that has a collaborative correspondence according to user operation; and non-collaboratively customizing and adjusting the parameter information of other welding parameters associated with the target parameter according to the parameter information of the collaboratively adjusted target parameter.

[0005] In conjunction with the first aspect, in the first possible implementation of the first aspect, the parameter information of the target parameters with a collaborative correspondence in the welding parameters is adjusted according to the user operation, including: determining the adjustable range of the welding parameters according to the target welding mode; and within the adjustable range, adjusting the parameter information of the target parameters with a collaborative correspondence in the welding parameters according to the user operation.

[0006] In conjunction with the first aspect, in the second possible implementation of the first aspect, the welding parameters include a first type of welding parameters and a second type of welding parameters. The first type of welding parameters includes at least one of welding process, tungsten electrode diameter, base material type, weld plate thickness, standard average welding current, and shielding gas type. The first type of welding parameters are inherent welding parameters in each welding mode. The second type of welding parameters includes average welding current, average wire feed speed, and weld plate thickness. The second type of welding parameters have a cooperative correspondence with other welding parameters.

[0007] In conjunction with the first aspect, in a third possible implementation of the first aspect, selecting a target welding mode from multiple welding modes includes: determining the target welding mode from multiple welding modes based on parameter information of a first type of welding parameters determined by the user; or, determining the target welding mode from multiple welding modes based on the identification information of the welding mode input by the user.

[0008] In conjunction with the first aspect, in the fourth possible implementation of the first aspect, the parameter information of other welding parameters associated with the target parameter is non-cooperatively customized and adjusted based on the parameter information of the target parameter after coordinated adjustment. This includes: adjusting the working amplitude of other welding parameters associated with the target parameter based on the parameter information of the target parameter after coordinated adjustment, and controlling the parameter information corresponding to the welding parameter to remain unchanged. The working amplitude includes influencing factors related to the parameter information of the welding parameter.

[0009] In conjunction with the first aspect, in the fifth possible implementation of the first aspect, after non-cooperatively customizing and adjusting the parameter information of other welding parameters associated with the target parameter based on the parameter information of the coordinated target parameter, the method further includes: generating a backup welding mode based on the parameter information of the adjusted welding parameters; and storing the backup welding mode.

[0010] In conjunction with the first aspect, in a sixth possible implementation of the first aspect, the method further includes: controlling the welding operation unit of the welding machine to perform welding operations based on the parameter information of the welding parameters in the backup welding mode.

[0011] In conjunction with the first aspect, in the seventh possible implementation of the first aspect, after non-cooperatively customizing the parameter information of other welding parameters associated with the target parameter based on the parameter information of the target parameter after cooperative adjustment, the method further includes: displaying the parameter information of some or all welding parameters in the target welding mode.

[0012] A second aspect of this application provides a welding parameter setting device applied to a welding machine. The welding machine has multiple pre-stored welding modes. In each welding mode, each welding parameter has parameter information corresponding to the welding mode. The device includes: a first response unit for responding to a first control operation and entering a first-level collaborative mode; a first determination unit for selecting a target welding mode from the multiple welding modes; a second determination unit for determining the parameter information of each welding parameter according to the target welding mode; a second response unit for responding to a second control operation, exiting the first-level collaborative mode, and entering a second-level collaborative mode; a first adjustment unit for collaboratively adjusting the parameter information of the target parameter among the welding parameters that has a collaborative correspondence according to user operation; and a second adjustment unit for non-collaboratively customizing and adjusting the parameter information of other welding parameters associated with the target parameter based on the parameter information of the collaboratively adjusted target parameter.

[0013] A third aspect of this application provides a welding machine, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the welding parameter setting method as described in any of the first aspects.

[0014] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method as described in any of the first aspects.

[0015] The beneficial effects of the embodiments in this application compared with the prior art are:

[0016] This application provides a welding parameter setting method. When a welding machine sets welding parameters based on this method, because the welding machine has multiple pre-stored welding modes, and each welding mode has parameter information corresponding to that mode, the welding machine can determine the target welding mode in a first-level collaborative mode according to user operation. In a second-level collaborative mode, the welding machine can perform collaborative and non-collaborative customized adjustments to the target parameters and other welding parameters associated with the target parameters in the target welding mode according to user operation. Through this method, the welding machine can achieve correlated collaborative adjustment of welding process parameters, thereby improving welding efficiency and adapting to the different special requirements of various welding applications for specific welding parameters.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0030] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are illustrated by specific embodiments below. It is worth noting that the specific embodiments listed below can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0031] Currently, in GTAW welding technology, welding operators typically set welding process parameters based on human-machine interface elements on the welding machine control panel. Figure 1 This is a plan view of the welding machine operation panel provided in an embodiment of this application. See also: Figure 1 The welding machine's control panel includes various human-machine interface elements, a display screen, and indicator lights. The human-machine interface elements allow users to select, set, or adjust welding process parameters. The display screen shows these parameters, and the indicator lights indicate the welding process parameters selected by the user. When the welding operator selects, sets, and adjusts welding process parameters using the human-machine interface elements on the control panel, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, the steps can usually be performed sequentially as follows:

[0032] First, select the welding process, then select the type of welding material (e.g., copper, aluminum, and steel). Next, select the type of shielding gas (e.g., nitrogen, argon, and helium) based on the type of welding material. Then, select, set, and adjust the standard average welding current based on the thickness of the welding material, and select and set the tungsten electrode diameter based on the standard average welding current. Further, select the welding speed and set the shielding gas flow rate based on the thickness of the welding material and the standard average welding current. Finally, determine the corresponding average welding voltage based on the tungsten electrode diameter, the standard average welding current, and the thickness of the welding material. Optionally, the welding machine can also display the specific parameter value of this average welding voltage on the display screen of the welding machine's operation panel.

[0033] Additionally, see Figure 3As shown, the welding operator also needs to select the energy waveform during welding according to the specific scenario of the welding application, such as DC waveform or AC waveform, single pulse or double pulse, three pulse or mixed pulse, rectangular pulse sequence or non-rectangular pulse wave sequence (triangular wave, trapezoidal wave, sine wave, or composite waveform sequence composed of the aforementioned basic waveforms, etc.).

[0034] Furthermore, the welding operator selects, sets, and adjusts the pulse amplitude, pulse time, base time, base current amplitude (the sum of base time and pulse time equals the pulse period, and its reciprocal is the pulse frequency), pulse current rise slope, and pulse current fall slope according to the energy waveform of the pulse welding.

[0035] Finally, depending on the specific welding application scenario, it is necessary to select whether to fill the wire. If fill the wire is required, the following settings need to be selected and / or set: wire type (usually the same as the material to be welded, but it can also be different), wire diameter, average wire feed speed, wire feed method (continuous or pulsating wire feed), hot wire or cold wire (preheated or unpreheated wire), etc. If it is pulsating wire feed, the frequency of pulsating wire feed also needs to be set.

[0036] As can be seen, after setting and adjusting the above series of parameters, the process of setting the welding parameters is complete. Then, the welding operation unit in the welding machine can automatically complete the welding operation according to the set parameters.

[0037] However, due to the wide variety of welding process parameters, and the fact that welding operators need to follow similar steps to those described above when selecting, setting, and adjusting welding process parameters using the human-machine interface on the welding machine's control panel, the process of setting welding process parameters is quite cumbersome and difficult, which in turn affects welding efficiency.

[0038] Based on this, this application provides a welding parameter setting method for welding machines. This method enables the rapid and coordinated setting of welding process parameters that match the specific application scenario of the welding process.

[0039] Before introducing the welding parameter setting method provided in the embodiments of this application, the structural components of the welding machine provided in the embodiments of this application will be briefly introduced first.

[0040] Figure 4 This is a schematic diagram of the structural components of the welding machine provided in an embodiment of this application. See also... Figure 4 As shown, the welding machine provided in this embodiment includes a control module, a database module, an operation module, a display module, and a communication module. The following explains each module in the welding machine.

[0041] The database module, also known as the storage module, is used to store parameter information for the execution of standard welding work corresponding to various welding parameters under different welding modes (also known as welding methods). The parameter information includes parameter values ​​or parameter types.

[0042] In this embodiment, the welding mode includes welding process and welding parameters. Typically, the welding process includes tungsten inert gas welding (GTAW), single-pulse GTAW-SP, and pulse-in-pulse GTAW-PEP (GTAW-PEP, where pulse-in-pulse can also be called pulse-within-pulse). Welding parameters include tungsten electrode diameter, base material type, plate thickness, average current, shielding gas type, standard average welding current, shielding gas flow rate, and energy waveform during welding. In some welding processes, when filler wire is required, the welding parameters also include filler wire type, filler wire diameter, average wire feed speed, wire feed method, wire feed frequency, and whether it is hot or cold wire. Each welding parameter has its own corresponding parameter information in different welding modes.

[0043] In this embodiment, parameter information refers not only to specific parameter values, but also to the parameter types corresponding to each parameter in the welding parameters. For example, when the welding parameter is the shielding gas type, the corresponding parameter type is various shielding gases, such as nitrogen, argon, and mixed gases; when the welding parameter is the wire feeding method, the corresponding parameter type is push-pull, wire feeding, push-pull wire feeding, etc.; when the welding parameter is the tungsten electrode diameter, the corresponding parameter value is 1mm, 2mm, or 3mm, etc. Furthermore, the parameter information corresponding to the standard welding operation refers to the rated parameter information (or preferred parameter information) for each welding parameter when welding materials of standard plate thickness. For example, when welding copper materials with a plate thickness of 2mm, the corresponding tungsten electrode diameter parameter value is 1mm, the standard average welding current parameter value is 40A, and the shielding gas parameter type is argon, etc.

[0044] For example, in the database module, the parameter information corresponding to the welding parameters under each welding mode can be stored in a sequential manner, such as welding mode 1, welding mode 2, and welding mode 3, and one welding mode corresponds to one combination method. For example, the correspondence between each welding mode and the parameter information of the welding parameters under each welding mode is shown in Table 1 below.

[0045] Table 1

[0046]

[0047] Referring to Table 1 above, in welding mode 1, the corresponding welding process is ordinary tungsten inert gas (TIG) welding. Among the welding parameters, the tungsten electrode diameter is a1, the type of material to be welded is stainless steel, the plate thickness is b1, the average current is c1, and the shielding gas type is argon plus hydrogen. It should be understood that each welding mode also includes other welding parameters besides the tungsten electrode diameter, base material type, plate thickness, standard average welding current, and shielding gas, such as the average wire feed speed and shielding gas flow rate. When storing these parameters in the database, each welding mode contains corresponding information on the average wire feed speed and shielding gas flow rate for that welding mode.

[0048] It should be noted that, during the welding process, some welding applications require the use of filler wire, while others do not. Therefore, when storing various welding modes, the database module includes welding parameters related to filler wire for some welding modes, such as wire type, wire diameter, and average wire feed speed, as shown in Welding Modes 1-3 (Methods 1-3) in Table 1 above. Conversely, some welding modes do not include welding parameters related to filler wire, as shown in Welding Mode 4 (Method 4) in Table 1 above. In this embodiment, multiple welding modes in the database module correspond to different welding application scenarios, thereby meeting the diverse needs of more types of welding applications.

[0049] The operation module is located on the welding machine's operation panel, allowing users to interact with the welding machine and adjust welding parameters.

[0050] In some embodiments, the operation module includes multiple operating elements disposed on the welding machine's operation panel, such as a mode switching element for switching operation modes and a parameter adjustment element for adjusting the values ​​of welding parameters. When the user operates the welding machine's operation panel through the operation module, the operation module sends corresponding instructions to the control module, and the control module completes the setting of welding parameters according to the instructions.

[0051] The display module is used to display parameter information for some or all of the process parameters in the currently selected welding parameters.

[0052] by Figure 1 Taking the welding machine operation panel shown as an example, this operation panel is equipped with an operation module and a display module. See [link / reference]. Figure 1 As shown, the operation module includes various operation adjustment buttons or knobs on the operation panel, and the display module includes the display screen and indicator lights on the operation panel.

[0053] The communication module is used to receive welding parameter information sent by the control module and send the parameter information to the welding operation unit of the welding machine.

[0054] The welding operation unit is used to perform welding operations based on the received welding parameter information.

[0055] The control module is used to set welding parameters according to the welding parameter setting method provided in the embodiments of this application. The following describes in detail the specific process of the control module in executing the welding parameter setting method in conjunction with the various structural components of the welding machine provided in this embodiment.

[0056] Figure 5 A flowchart illustrating the welding parameter setting method provided in this application embodiment is shown below. Figure 5 As shown, the method includes the following steps S501 to S508.

[0057] S501, the control module responds to the first control operation and enters the first-level collaborative mode.

[0058] In some embodiments, the first control operation may be a user's control operation on the mode switching element in the operation module set on the welding machine operation panel. For example, the user presses the mode switching element, the operation module responds to the operation by generating a mode switching command, and sends the mode switching command to the control module. After receiving the mode switching command, the control module enters the first-level cooperative mode.

[0059] In other embodiments, the first control operation can also be a direct control operation by the user on the control module. For example, the user toggles the mode switching function key on the control module, and the control module responds to the control operation and enters the first-level collaborative mode.

[0060] by Figure 1 The welding machine operation panel shown is for reference. After the user performs the first control operation by pressing the function key Fn, the control module can be triggered to enter the first-level collaborative mode.

[0061] In this embodiment, the first-level collaborative mode, also known as the welding method selection mode, allows for the selection of the corresponding welding method based on the specific material to be welded or the welding requirements.

[0062] S502, the control module selects the target welding mode from multiple welding modes.

[0063] S503, the control module determines the parameter information of each welding parameter according to the target welding mode.

[0064] In this embodiment, the welding machine pre-stores multiple welding modes. Within each welding mode, various welding parameters have parameter information corresponding to that mode. Optionally, the multiple welding modes can be pre-stored in the welding machine's database module, and the control module can retrieve the corresponding welding mode from the database module based on user operations; alternatively, they can be pre-stored in the control module's storage unit, and the control module can directly retrieve the corresponding welding mode from the storage unit based on user operations. Each welding mode in the welding machine includes parameter information for a first type of welding parameter and a second type of welding parameter.

[0065] The first category of welding parameters includes at least one of the following: welding process, tungsten electrode diameter, base material type, plate thickness, standard average welding current, and shielding gas type. The second category of welding parameters includes all welding parameters involved in the welding process other than those in the first category, such as average welding current, average wire feed speed, weld plate thickness, shielding gas flow rate, and energy waveform during welding. The control module can adjust the parameter information of the target parameter in the first and / or second categories of welding parameters to coordinately adjust the parameter information of other welding parameters in the first and / or second categories that have a synergistic relationship with the target parameter. It should be noted that in this embodiment, the division between the first and second categories of welding parameters is not mutually exclusive. A certain welding parameter may belong to either the first or the second category, such as the average welding current. The first category of welding parameters can be understood as the inherent welding parameters in various welding modes or general welding parameters; the second category of welding parameters can be understood as the set of welding parameters with synergistic relationships among all welding parameters.

[0066] In some embodiments, the control module determines a target welding mode among multiple welding modes based on user operations, including the control module determining the target welding mode among multiple welding modes based on the user's selection operation of a first type of welding parameters.

[0067] Similarly, with Figure 1The welding machine control panel shown is for reference. After the user performs the first control operation by pressing the function key Fn, the control module enters the first-level collaborative mode. In this collaborative mode, the control module can determine the target welding mode based on the user's operation. For example, when the user rotates the right knob R in the illustration, the control module can simultaneously select the welding mode corresponding to the specified position reached by the rotated knob (rotating the knob to a certain position represents the user selecting the corresponding welding mode at that position), and simultaneously perform welding modes such as GTAW, GTAW-SP, and GTAW-PEP. In the welding process, one option is selected: one option is selected from the shielding gas categories (Ar, He, Ar+He, Ar+H2, and backup); one option is selected from the tungsten electrode diameter (mm) (2.0, 2.4, 3.2, 4.0, and backup); one option is selected from carbon steel, stainless steel, and other materials to be welded; one option is selected from the plate thickness (cm) (1.0, 1.4, 2.8, 3.2, 5.0, and backup); and one option is selected from the standard average welding current (A) (50, 60, 80, 100, 120). It should be noted that each welding parameter in each welding mode has parameter information corresponding to that welding mode. Therefore, after the control module determines the welding process and the parameter information of each welding parameter in the first category based on the user's operation, it can determine the corresponding target welding mode and the parameter information of the second category of welding parameters in that target welding mode. For example, in the target welding mode determined by the control module, the welding process, the parameter information of the first type of welding parameters, and the parameter information of the second type of welding parameters can be represented by Table 2.

[0068] Table 2

[0069]

[0070]

[0071] In other embodiments, the control module can determine the target welding mode from multiple welding modes based on the identification information of the welding mode input by the user. For example, the user inputs the welding method number corresponding to the welding mode at the welding mode selection position on the welding machine operation panel, such as method 55. The control module then retrieves the target welding mode corresponding to method 55 from the database module based on the user-input method 55, as well as the parameter information of the first type of welding parameters and the second type of welding parameters under the target welding mode.

[0072] In some embodiments, the control module may also determine the target welding mode from multiple welding modes based on the parameter information of a specific welding parameter in the first type of welding parameters, such as the tungsten electrode diameter.

[0073] It should be noted that, in this embodiment, see Figure 6As shown, the associated combination of tungsten electrode diameter, base material type, plate thickness, standard average welding current, and shielding gas type in the first category of welding parameters can determine a specific welding mode among multiple welding modes. That is, changing any one of these five welding parameters can form a unique GTAW welding mode. For example, when the parameter information corresponding to the other four welding parameters is consistent, when the control module responds to the operation of changing the tungsten electrode diameter to coordinately change the welding method, that is, when the tungsten electrode diameter is adjusted, the other four parameters will be automatically and coordinated in a preferred manner, and the determined target welding mode will also be adjusted accordingly.

[0074] Because the selection, setting, and / or adjustment of each welding parameter has a strong logical correlation with the selection, setting, and / or adjustment of other welding parameters, which is closely related to welding performance, in this embodiment, under the first-level collaborative mode, when determining the target welding mode, the parameter information of other welding parameters can be changed collaboratively by adjusting the parameter information of one welding parameter. This solves the problems in traditional technology where, when setting parameters sequentially, changing the parameter information of one welding parameter requires corresponding adjustment of the parameter information of other welding parameters. This results in low efficiency (due to the cumbersome, time-consuming, and labor-intensive process of selecting, setting, and / or adjusting welding parameters) and high cost (due to the high requirements for welders' theoretical knowledge and practical experience, necessitating the search for highly skilled and experienced labor) when selecting, setting, and / or adjusting the parameter information of some strongly related welding parameters.

[0075] S504. The control module responds to the second control operation, exits the first-level collaborative mode, and enters the second-level collaborative mode.

[0076] In this embodiment, in order to make the set welding parameters better adapt to the specific welding requirements, after the control module determines the target welding mode, the parameter information of some welding parameters in the target welding mode can be adjusted.

[0077] When the control module is adjusting the welding parameters, it needs to first exit the first-level collaborative mode and enter the second-level collaborative mode. Then, it can adjust the parameter information of some welding parameters in the target welding mode in the second-level collaborative mode.

[0078] In some embodiments, the control module can exit the first-level collaborative mode and enter the second-level collaborative mode by responding to a second control operation. For example, if the user presses the function key Fn again in the first-level collaborative mode, the control module can respond to the second control operation and exit the first-level collaborative mode to enter the second-level collaborative mode. Optionally, during this process, the control module can display welding information of some or all welding parameters in the target welding mode on the welding machine operation panel via a display screen or indicator lights. For example, see [link to example]. Figure 1 As shown, the control module can control the... Figure 1 The left display screen BCD1 and the right display screen BCD2, in the indicated direction, display the parameter value of the shielding gas percentage for 3 seconds. After that, the parameter value of the standard average welding current is displayed on the left display screen BCD1, and the parameter value of the reference, corresponding standard average welding voltage is displayed on the right display screen BCD2.

[0079] S505, The control module adjusts the parameter information of the target parameters with a coordinated relationship in the welding parameters according to the user's operation.

[0080] In some embodiments, the control module first determines the adjustable range of the first type of welding parameters and / or the second type of welding parameters (i.e., the range between the minimum and maximum values ​​of the extended parameter values) based on the parameter information of the first type of welding parameters, and then adjusts the parameter information of the target parameter in the first type of welding parameters and / or the second type of welding parameters according to the user operation within the adjustable range.

[0081] It should be noted that once the target welding mode is determined, the parameter information corresponding to each welding parameter in the target welding mode can be determined. However, in the secondary collaborative mode, when it is necessary to adjust the parameter information of the first type of welding parameters and / or the second type of welding parameters, it is necessary to determine the adjustable range of the first type of welding parameters and / or the second type of welding parameters based on the determined parameter information of the first type of welding parameters. Then, within this adjustable range, the parameter information of the target parameters in the second type of welding parameters is determined according to the user operation.

[0082] For example, in the target welding mode, if the tungsten electrode diameter is determined to be 1 mm, the corresponding standard average welding current is 50 A, and the corresponding standard average cold wire feed speed is 2.0 m / min. However, when the tungsten electrode diameter is 1 mm, the adjustable range of the corresponding standard average welding current and average cold wire feed speed is limited. For example, the adjustable range of the standard average welding current is 20 A to 100 A, and the adjustable range of the average cold wire feed speed is 0.5 m / min to 5 m / min. Therefore, the control module can determine the parameter values ​​of the average wire feed speed and / or average welding current within the adjustable range of the average cold wire feed speed and / or average welding current based on the user's adjustment operation.

[0083] In some embodiments, if the tungsten electrode diameter is determined to be 1 mm in the target welding mode, the corresponding standard average welding current is 50 A, and the corresponding standard average cold wire feed speed is 2.0 m / min. However, there is a relationship between the average welding current and the average cold wire feed speed. Figure 7 The linear relationship shown indicates that the standard average welding current can be adjusted accordingly based on the user's adjustment of the average cold wire feed speed. As mentioned earlier, when the tungsten electrode diameter is 1mm, the adjustable range (also known as the extended range) of the standard average welding current is 20A to 100A (where 20A is the minimum extended parameter value and 100A is the maximum extended parameter value), and the adjustable range of the average cold wire feed speed is 0.5m / min to 5m / min (where 0.5m / min is the minimum extended parameter value and 5m / min is the maximum extended parameter value). Therefore, if, according to user operation, the control module changes the standard average welding current from the standard parameter value of 50A to the extended parameter value of 100A, the average cold wire feed speed is also correspondingly changed from the standard parameter value of 1.0m / min to the extended parameter value of 5m / min. Simultaneously, optionally, the control module can control... Figure 1 The left-hand display screen (BCD1) on the control panel of the welding machine shows the adjusted average welding current. Furthermore, the control module can also display the adjusted average welding current value on the left-hand display screen (BCD1) after the user presses the left-hand triangle key (Δ) to set the average wire feed speed. Additionally, if the average cold wire feed speed needs to be adjusted separately, the control module can respond to the user's operation of rotating the left-hand knob (L) to control the display screen (BCD1) to show the average cold wire feed speed value. Finally, the control module can respond to the user's continuous pressing of the left-hand triangle key (Δ) to control the left-hand display screen (BCD1) to resume displaying the average welding current.

[0084] Additionally, see Figure 8 The diagram showing the relationship between average welding current and plate thickness demonstrates that the control module can also adjust the average welding current parameters in accordance with changes in plate thickness parameters.

[0085] It should be noted that in this embodiment, the standard average welding voltage, which is a welding parameter, changes automatically and collaboratively with the operation of the first-level collaborative mode and the second-level collaborative mode, but cannot be changed independently. That is, the parameter value of the standard average welding voltage is advisory and only responds collaboratively and passively. The control module cannot change the standard average welding voltage and the resulting changes in the parameter information of other first-class and second-class welding parameters through the user's operation of the components on the welding machine operation panel.

[0086] S506. The control module, based on the parameter information of the target parameter after coordinated adjustment, non-coordinatedly customizes and adjusts the parameter information of other welding parameters associated with the target parameter.

[0087] In some embodiments, the control module can adjust the parameter information of the target parameter in the first type of welding parameters according to the user operation in a two-level collaborative mode, and then, based on the adjusted parameter information of the target parameter in the first type of welding parameters, non-collaboratively customize and adjust the parameter information of the second type of welding parameters corresponding to the target parameter.

[0088] For example, after determining the target welding mode, the control module also determines the parameter information of each welding parameter under the target welding mode. The plate thickness and shielding gas flow rate in the first type of welding parameters can also be automatically changed in a coordinated manner within a certain range. When the parameter information of the plate thickness and shielding gas flow rate in the first type of welding parameters is changed, the parameter information of the second type of welding parameters that has a coordinated correspondence with the plate thickness and shielding gas flow rate is also changed accordingly.

[0089] In this embodiment, to meet the special requirements of personalized, dedicated GTAW, the control module can also respond to adjustments to the parameter information of other welding parameters associated with the target parameters. For example, it can adjust the working amplitude of the welding parameters while keeping the standard parameter values ​​of the corresponding welding parameters constant. The working amplitude includes influencing factors related to the parameter information of the corresponding welding parameters, such as the current pulse frequency, pulse amplitude, width, and base amplitude related to the pulse current parameter. That is, in the target welding mode, the parameter information of the welding parameters can be individually fine-tuned statically and dynamically as a percentage while keeping their respective parameter values ​​constant.

[0090] For example, adjusting the standard average welding current: The control module increases or decreases the average welding current by a percentage based on the user's actions of pressing the left triangle key Δ to select the current percentage and rotating the left knob L. It also ensures that other welding parameters that are correlated with this average welding current remain unchanged, and displays the current percentage value on the left display screen BCD1 of the welding machine's operation panel. Subsequently, the control module can display the final average welding current on the left display screen BCD1 again based on the user's action of pressing the left triangle key Δ again.

[0091] For example, the operating amplitude of the pulse current parameters can be adjusted. This means that the pulse frequency, pulse amplitude and width, and base value amplitude, all based on the average welding current parameter, can be adjusted. Specifically, the pulse frequency can be adjusted by regulating the base value duration, as detailed in the following section: [See details]. Figure 1As shown on the control panel of the welding machine, the control module controls the right-side display screen BCD2 to display the corresponding set values ​​based on the user's actions, such as pressing the arc performance button until the "Alternate 1" option is selected (at this time, the control module controls the corresponding LED to light up) and rotating the right knob R. (It should be noted that in single-pulse welding, the pulse frequency is the pulse frequency itself; while in composite pulse (pulse-in-pulse) welding, the pulse frequency is the frequency of the low-frequency pulse). The pulse amplitude and width, as well as the base amplitude, can be fine-tuned by changing the percentage of the corresponding parameter in the system's C-level parameters (the name of the corresponding parameter is displayed on the left-side display screen BCD1, and the percentage value of the parameter is displayed on the right-side display screen BCD2).

[0092] For example, adjusting the operating amplitude of the cold wire feeding parameters. It should be understood that the average cold wire feeding speed based on the average welding current in this embodiment refers to the pulsating wire feeding speed. The frequency of this pulsating wire feeding speed is the same as the frequency of the low-frequency pulse current (it can be indirectly adjusted to the same frequency by adjusting the frequency of the current pulse). The control module's response to the pulsating wire feeding adjustment is achieved through the two standby options of the arc performance button (for example, the control module responds to the user's operation of adjusting the right-side knob, controlling the display on the right-side display BCD2 to show 1 (pulsating) or -1 (continuous), 0 (wire stopped)), and keeps the average cold wire feeding speed constant.

[0093] In this embodiment, based on the selection of welding mode in the first-level collaborative mode and the adjustment of welding parameter information in the second-level collaborative mode, the control module adopts separate adjustment of the first type of welding parameters (such as average welding current) and / or the second type of welding parameters (such as average cold wire feed speed), as well as the working amplitude of the first type of welding parameters and / or the second type of welding parameters (such as the extended parameter value adjustment method for whether wire is fed and whether wire feeding pulsation is present; if the selected welding process is pulse welding process, the pulse frequency, pulse amplitude and width of the current waveform, as well as the base amplitude (which may also include the current rise rate and fall rate)) to precisely meet the parameter selection and fine adjustment process of the dedicated GTAW, and better adapt to the special needs of personalized welding.

[0094] S507. The control module generates and stores a backup welding mode based on the adjusted welding parameter information.

[0095] In some embodiments, the control module can generate a backup welding mode based on the parameter information of the adjusted welding parameters, and store the backup welding mode in the database module or the storage unit of the control module to enrich the welding mode database. The backup welding mode can be directly called when welding is selected in the future.

[0096] S508: The control module controls the welding operation unit of the welding machine to perform welding operations based on the parameter information of the welding parameters in the backup welding mode.

[0097] In some embodiments, the control module sends the welding parameter information of the standby welding mode to the welding operation unit of the welding machine through the communication module, so that the welding operation unit can perform the corresponding welding operation according to the parameter information.

[0098] In other embodiments, the control module can also directly control the welding operation unit of the welding machine to complete the welding operation based on the parameter information of the welding parameters in the backup welding mode.

[0099] It should be emphasized that, in this embodiment, after the control module determines the target welding mode in the first-level collaborative mode, when entering the second-level collaborative mode, both the first type of welding parameters and the second type of welding parameters can be dynamically and collaboratively changed or adjusted during the welding process.
