[0028] The present application will be further described in detail below by means of the drawings and embodiments. Through these descriptions, the features and advantages of the present application will become more apparent.

[0029] The term "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The disclosure can lie in none, some, or all examples of any embodiment(s). While the drawings illustrate various aspects of embodiments, the drawings are not necessarily to scale, unless specifically stated.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0031] In order to facilitate understanding, first, the application scene of the technical scheme of the present application is introduced.

[0032] With the development of welding technology, the welding method becomes various, which has been changed from the original electrode arc welding to the gas shielded welding, plasma arc welding, laser welding and other welding methods. Among them, in order to improve the welding efficiency and improve the welding quality, the gas shielded welding is applied more and more widely.

[0033] The gas shielded welding has the following advantages: high efficiency, fast welding speed; large penetration, small welding deformation; various position welding can be realized, strong flexibility; clear arc operation, easy to observe the molten pool and arc. Under the premise of wide application of gas shielded welding, people put forward higher requirements on welding speed and welding quality, and the pulsed gas shielded welding (referred to as pulse welding) emerges as the times require. Pulse welding has the advantages that traditional gas shielded welding does not have, its welding process is more stable, spatter is less, and material loss is less. However, sometimes affected by the site working condition and the base material, magnetic blowout often occurs in the pulse welding process, which leads to unstable welding process, causes poor weld forming and frequent welding defects, and even causes the welding product to be scrapped.

[0034] Magnetic blowout refers to that due to some reasons, the uniformity of magnetic field lines is destroyed, so that the force around the arc is uneven and deviates to one side. This phenomenon that makes the arc deviate from the axis of the welding wire is called arc blowout, simply referred to as magnetic blowout.

[0035] The inventors found in specific application and research that the difference (or difference value) between the pulse peak current and the pulse base current, and the pulse rise time and the pulse fall time have great influence on the magnetic blowout in the pulse welding process. The smaller the difference between the pulse peak current and the pulse base current, the less likely the magnetic blowout occurs. The longer the pulse rise time and the pulse fall time, the less likely the magnetic blowout occurs.

[0036] Based on this, in order to be able to reduce or eliminate the influence of magnetic blowout on the efficiency and effect of pulse welding, the application provides a magnetic blowout processing method, device and welding system. In the method, the controller can obtain the actual pulse base value voltage after the start of any one pulse period of pulse welding, and then determine whether magnetic blowout occurs in the first pulse period based on the actual pulse base value voltage and the first preset pulse base value reference voltage used to determine magnetic blowout, and after determining that magnetic blowout occurs, increase the pulse rise time and pulse fall time in the next pulse period of the pulse period, and reduce the pulse peak current, so as to perform pulse welding in the next pulse period based on the adjusted pulse rise time, pulse fall time and pulse peak current, thereby improving the anti-interference ability of the pulse arc to magnetic blowout, ensuring the droplet transfer state of one pulse one drop, so that the arc can maintain good stability during welding, thereby reducing or eliminating the influence of magnetic blowout on the efficiency and effect of pulse welding, making the pulse welding efficiency higher and the pulse welding effect better.

[0037] The magnetic blowout processing method provided by the embodiments of the application will be described below with reference to the accompanying drawings.

[0038] Referring to Figure 1 , Figure 1 A flowchart of a magnetic blowout processing method provided by an embodiment of the application. The method can be applied to a terminal device or a controller provided in a welding system. The following will take a controller provided in a welding system (hereinafter referred to as a controller) as an example to describe the embodiments of the application. As shown in Figure 1 , the method can include the following steps:

[0039] Step S101, after the start of the first pulse period, pulse welding is performed with the first welding parameters.

[0040] It should be noted that, in order to ensure the efficiency of magnetic blowout processing and eliminate the influence of magnetic blowout on the efficiency and effect of pulse welding to the greatest extent, it is necessary to determine whether magnetic blowout occurs in each pulse period in real time and process magnetic blowout in time when it occurs. However, based on the same magnetic blowout processing mode in each pulse period, the embodiments of the application will be described taking the first pulse period as an example.

[0041] Among them, the first pulse period is any one pulse period in pulse welding. The first welding parameter includes the welding parameter obtained after adjusting the welding parameter based on the second pulse period. The second pulse period is the last pulse period of the first pulse period.

[0042] Optionally, the first welding parameter can include a first pulse rise time, a first pulse fall time and a first pulse peak current. The first pulse rise time is adjusted based on the pulse rise time of the second pulse period. The first pulse fall time is adjusted based on the pulse fall time of the second pulse period. The first pulse peak current is adjusted based on the pulse peak current of the second pulse period.

[0043] Optionally, when the first pulse period is the first pulse period after the start of the pulse welding, there is no second pulse period. In this application scenario, the first welding parameter can be a preset welding parameter. Optionally, the preset welding parameter can include a preset pulse rise time, a preset pulse fall time and a preset pulse peak current. Based on this, the first pulse rise time can be the preset pulse rise time, the first pulse fall time can be the preset pulse fall time, and the first pulse peak current can be the preset pulse peak current.

[0044] Optionally, when the first pulse period is any one of the pulse periods after the start of the pulse welding, there is a second pulse period, and the first pulse rise time, the first pulse fall time and the first pulse peak current can be determined based on the pulse rise time, the pulse fall time and the pulse peak current of the second pulse period, respectively. For details, please refer to the contents of the subsequent embodiments, which will not be described here.

[0045] After the start of the first pulse period, the controller can determine the first pulse rise time as the pulse rise time of the first pulse period, determine the first pulse fall time as the pulse fall time of the first pulse period, and determine the first pulse peak current as the pulse peak current of the first pulse period, and perform pulse welding.

[0046] It should be noted that the first welding parameter can also include other welding parameters, such as welding voltage, wire feeding speed, etc., which are not limited by the present application.

[0047] In step S102, the actual pulse base value voltage is obtained.

[0048] In one possible implementation, the first preset pulse base value reference voltage can be stored in advance in a storage device in communication connection with the controller. The first preset pulse base value reference voltage is used to determine whether magnetic blowout occurs in the pulse welding. Optionally, the first preset pulse base value reference voltage can be set according to the requirements of the actual application scenario.

[0049] Before or after obtaining the actual pulse base value voltage, the controller can also read the first preset pulse base value reference voltage from the storage device in communication connection with the controller, which is used to determine whether magnetic blowout occurs subsequently.

[0050] After the first pulse cycle starts, the controller can obtain the actual pulse base value voltage in real time during the pulse welding process.

[0051] In step S103, whether magnetic blowout occurs is determined based on the actual pulse base value voltage and a first preset pulse base value reference voltage.

[0052] After the controller obtains the actual pulse base value voltage each time, the controller can compare the obtained actual pulse base value voltage with the first preset pulse base value reference voltage. If the obtained actual pulse base value voltage is greater than or equal to the first preset pulse base value reference voltage, it is determined that magnetic blowout occurs. Or, if the obtained actual pulse base value voltage is less than the first preset pulse base value reference voltage, it is determined that magnetic blowout does not occur at present.

[0053] Before the next pulse cycle of the first pulse cycle starts, if all the actual pulse base value voltages obtained by the controller are less than the first preset pulse base value reference voltage, it is determined that magnetic blowout does not occur before the next pulse cycle of the first pulse cycle starts, i.e., the controller can determine that magnetic blowout does not occur in the first pulse cycle.

[0054] Conversely, before the next pulse cycle of the first pulse cycle starts, if the controller obtains an actual pulse base value voltage greater than or equal to the first preset pulse base value reference voltage, it is determined that magnetic blowout occurs, i.e., the controller can determine that magnetic blowout occurs in the first pulse cycle.

[0055] In step S104, if magnetic blowout occurs, the pulse rise time and the pulse fall time in the next pulse cycle of the first pulse cycle are increased, and the pulse peak current is reduced.

[0056] After the first pulse cycle starts, the controller can increase the pulse rise time and the pulse fall time in the next pulse cycle of the first pulse cycle and reduce the pulse peak current in the next pulse cycle of the first pulse cycle after determining that magnetic blowout occurs in the first pulse cycle, so that the influence of magnetic blowout on the pulse welding efficiency and the pulse welding effect can be reduced or eliminated in the next pulse cycle of the first pulse cycle, thereby improving the pulse welding efficiency and the pulse welding effect.

[0057] In a possible implementation, after the controller determines that magnetic blowout occurs, the pulse rise time and the pulse fall time in the next pulse cycle of the first pulse cycle are increased, and the pulse peak current in the next pulse cycle of the first pulse cycle is reduced, which can be implemented in the following manner:

[0058] If the actual pulse base value voltage is greater than or equal to the first preset pulse base value reference voltage and less than or equal to the second preset pulse base value reference voltage, the second pulse rise time, the second pulse fall time and the second pulse peak current can be determined according to the following formulas (1), (2) and (3):

[0059] L2 = L1 + K1 * (Us - Ua) (1)

[0060] S2 = S1 + K2 * (Us - Ua) (2)

[0061] I2 = I1 + K3 * (Us - Ua) (3)

[0062] The pulse rise time of the next pulse period of the first pulse period is increased to the second pulse rise time, the pulse fall time of the next pulse period of the first pulse period is increased to the second pulse fall time, and the pulse peak current of the next pulse period of the first pulse period is reduced to the second pulse peak current.

[0063] Wherein, L1 represents the first pulse rise time, S1 represents the first pulse fall time, I1 represents the first pulse peak current, L2 represents the second pulse rise time, S2 represents the second pulse fall time, I2 represents the second pulse peak current, Us represents the actual pulse base value voltage, Ua represents the first preset pulse base value reference voltage, K1, K2, K3 are all constants, K1 and K2 are greater than zero, and K3 is less than zero. The specific values of K1, K2 and K3 can be set according to the requirements of the actual application scene, as long as the energy output in each pulse period remains unchanged, that is, the energy output in the first pulse period is the same as the energy output in the next pulse period of the first pulse period.

[0064] Wherein, the first preset pulse base value reference voltage is less than the second preset pulse base value reference voltage. The values of the first preset pulse base value reference voltage and the second preset pulse base value reference voltage can also be set according to the requirements of the actual application scene.

[0065] In such an application scenario, in the next pulse period of the first pulse period, the controller can determine the second pulse rise time, the second pulse fall time and the second pulse peak current as the pulse rise time, the pulse fall time and the pulse peak current of the pulse period respectively, and perform pulse welding.

[0066] For example, referring to the waveform diagram of the actual welding voltage (referred to as voltage, unit: volt V) and the actual welding current (referred to as current, unit: ampere A) changing with time T (unit: millisecond ms) as shown in Figure 2 Figure 2 ​As shown, if the actual pulse base voltage Us is greater than the first preset pulse base reference voltage Ua and less than the second preset pulse base reference voltage Um, then the pulse rise time, pulse fall time, and pulse peak current in the next pulse cycle of the first pulse cycle can be adjusted in the manner described above. The pulse waveforms before and after adjustment can be referenced. Figure 3 .like Figure 3 As shown, the pulse rise time, pulse fall time, and pulse peak current in the first pulse cycle are the first pulse rise time L1, the first pulse fall time S1, and the first pulse peak current I1, respectively. After adjustment, the pulse rise time, pulse fall time, and pulse peak current in the next pulse cycle of the first pulse cycle are the second pulse rise time L2, the second pulse fall time S2, and the second pulse peak current I2, respectively.

[0067] In one possible implementation, after the controller determines that magnetic blow has occurred, it increases the pulse rise time and pulse fall time in the next pulse cycle of the first pulse cycle and decreases the pulse peak current in the next pulse cycle of the first pulse cycle. This can also be achieved in the following manner:

[0068] If the actual pulse base voltage is greater than the second preset pulse base reference voltage, the rise time, fall time and peak current of the third pulse can be determined according to the following formulas (4), (5) and (6):

[0069] L3=L1+K4*(Um-Ua) (4)

[0070] S3=S1+K5*(Um-Ua) (5)

[0071] I3=I1+K6*(Um-Ua) (6)

[0072] The pulse rise time in the next pulse cycle of the first pulse cycle is increased to the third pulse rise time, the pulse fall time in the next pulse cycle of the first pulse cycle is increased to the third pulse fall time, and the pulse peak current in the next pulse cycle of the first pulse cycle is decreased to the third pulse peak current.

[0073] Wherein, L1 represents the first pulse rise time, S1 represents the first pulse fall time, I1 represents the first pulse peak current, L3 represents the third pulse rise time, S3 represents the third pulse fall time, I3 represents the third pulse peak current, Um represents the second preset pulse base value reference voltage, Ua represents the first preset pulse base value reference voltage, K4, K5, K6 are all constants, K4 and K5 are greater than zero, K6 is less than zero, K4 is greater than K1, K5 is greater than K2, and K6 is less than K3. The specific values of K4, K5 and K6 can be set according to the requirements of the actual application scene, as long as the energy output in each pulse period remains unchanged, that is, the energy output in the first pulse period is the same as the energy output in the next pulse period of the first pulse period.

[0074] In the next pulse period of the first pulse period in such an application scenario, the controller can determine the third pulse rise time, the third pulse fall time and the third pulse peak current as the pulse rise time, the pulse fall time and the pulse peak current of the pulse period, respectively, to perform pulse welding.

[0075] It should be noted that in the above two implementation manners of increasing the pulse rise time and the pulse fall time in the next pulse period of the first pulse period and reducing the pulse peak current in the next pulse period of the first pulse period, the actual pulse base value voltage can be the actual pulse base value voltage greater than or equal to the first preset pulse base value reference voltage obtained for the first time in the first pulse period, or can be the maximum value of the actual pulse base value voltage obtained in the first pulse period.

[0076] That is, after the start of the first pulse period, the controller can obtain the actual pulse base value voltage in real time, and after obtaining the actual pulse base value voltage greater than or equal to the first preset pulse base value reference voltage for the first time, the controller can adjust the pulse rise time, the pulse fall time and the pulse peak current in the next pulse period of the first pulse period based on the actual pulse base value voltage.

[0077] Alternatively, in order to improve the processing efficiency of magnetic deflection and reduce or eliminate the influence of magnetic deflection on the efficiency and effect of pulse welding to a greater extent, the controller can adjust the pulse rise time, the pulse fall time and the pulse peak current in the next pulse period of the first pulse period based on the maximum value of the actual pulse base value voltage obtained in the first pulse period.

[0078] In a possible implementation, when all the actual pulse base value voltages obtained by the controller in the first pulse period are less than the first preset pulse base value reference voltage, the controller can determine that magnetic blowout does not occur in the first pulse period. In this application scenario, the pulse rise time, the pulse fall time and the pulse peak current of the next pulse period of the first pulse period do not need to be adjusted. The pulse rise time, the pulse fall time and the pulse peak current of the next pulse period of the first pulse period can be respectively determined as the pulse rise time, the pulse fall time and the pulse peak current of the first pulse period. That is, the pulse rise time, the pulse fall time and the pulse peak current of the next pulse period of the first pulse period can be respectively determined as the first pulse rise time, the first pulse fall time and the first pulse peak current. Then, in the next pulse period of the first pulse period, the controller can perform pulse welding in the pulse period based on the first pulse rise time, the first pulse fall time and the first pulse peak current.

[0079] It should be noted that, Figure 1 The embodiment shown is used as an example of the first pulse period to describe the magnetic blowout processing method of the present application. In actual pulse welding application scenarios, after the pulse welding starts, the magnetic blowout processing method shown can be used to perform magnetic blowout processing in each pulse period, so as to improve the anti-interference ability of the pulse arc to the magnetic blowout, ensure the droplet transfer state of one pulse one drop, and make the arc in the welding process keep good stability, thereby reducing or eliminating the influence of the magnetic blowout on the pulse welding efficiency and the pulse welding effect, making the pulse welding efficiency higher and the pulse welding effect better.
