In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, in the description of the present application and the appended claims, the terms "first," "second," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise.
The first embodiment is as follows:
in the continuous spot welding process, usually, in each spot welding in the continuous spot welding process, arc striking is carried out at a slow wire feeding speed so as to improve the success rate of arc striking. However, the slow wire feeding speed leads the arc striking speed of each spot welding to be slow, so that the efficiency of continuous spot welding is low.
In order to improve the success rate of arc striking and the efficiency of continuous spot welding, the embodiment of the application provides a welding control method.
In the control method, if the current spot welding is judged to be the first spot welding of the continuous spot welding, arc striking is carried out at a set first wire feeding speed, and if the current spot welding is judged not to be the first spot welding of the continuous spot welding, arc striking is carried out at a second wire feeding speed which is higher than the first wire feeding speed.
Because the spot welding is carried out before the non-first spot welding in the continuous spot welding, and the welding wire after the spot welding keeps certain heat, the arc striking success rate of the non-first spot welding cannot be reduced by adopting the second wire feeding speed which is higher than the first wire feeding speed for arc striking, the arc striking speed can be increased, and the integral efficiency of the continuous spot welding is improved.
The welding control method provided by the embodiment of the invention is described below with reference to the accompanying drawings.
Fig. 1 shows a schematic flow chart of a welding control method provided by an embodiment of the present invention, which is detailed as follows:
and step S11, in the continuous spot welding process, if the current spot welding is the first spot welding, arc striking is carried out at a first wire feeding speed.
The continuous spot welding is to form a continuous weld seam through a series of connected or repeated spot welds, or a series of unconnected individual weld spots.
The arc initiation refers to a process of igniting an arc by a welding wire during welding.
In the continuous spot welding process, if the welding machine is started for the first time to carry out spot welding or the current spot welding is judged not to meet the requirement of non-first spot welding, the current spot welding is changed into the first spot welding in a new continuous spot welding stage, and at the moment, arc striking is carried out at a first wire feeding speed. For example, in a certain continuous spot welding process, the welding machine is started for the first time to perform spot welding, the first spot welding started for the first time is the first spot welding of the continuous spot welding in the first stage, and at this time, arc striking is performed at the first wire feeding speed.
In the embodiment of the application, the first set wire feed speed is adopted for arc striking for spot welding which is judged to be spot welding for the first time in the continuous spot welding process, so that the proper wire feed speed is adopted for arc striking when the spot welding is carried out for the first time, the conditions of reverse burning, wire jacking and the like caused by too low or too high wire feed speed are avoided, and the arc striking success rate is improved.
And step S12, if the current spot welding is not the first spot welding, arc striking is carried out at a second wire feeding speed.
Wherein the second wire feed speed is greater than the first wire feed speed.
In the continuous spot welding process, when the current spot welding is not the first spot welding, arc striking of the non-first spot welding is performed at a second wire feeding speed which is higher than the first wire feeding speed. Because the current spot welding is the non-primary spot welding, namely, the spot welding has been carried out before the current spot welding, and the welding wire is in a state of keeping certain heat, the arc striking of the non-primary spot welding is carried out by adopting the wire feeding speed which is higher than the first wire feeding speed, namely, the arc striking success rate of the current spot welding is not influenced by adopting the second wire feeding speed. And moreover, the second wire feeding speed is higher than the first wire feeding speed, so that the arc striking speed of the current spot welding is increased, the efficiency of continuous spot welding is increased, and the production cost of enterprises is reduced.
In the embodiment of the application, the first spot welding in the continuous spot welding process is subjected to arc striking at the first wire feeding speed, and the non-first spot welding is subjected to arc striking at the second wire feeding speed. Because when the first spot welding, adopt lower wire feed speed, consequently, can improve this first spot welding's striking success rate, but when not first spot welding, because spot welding has been carried out before the non-first spot welding, the welding wire has kept certain heat, consequently, adopt the second wire feed speed that is greater than first wire feed speed to carry out the striking of non-first spot welding, not only can guarantee this non-first spot welding's striking success rate, also can improve the striking speed of non-first spot welding, thereby continuous spot welding efficiency has been improved, reduce the required time of continuous spot welding, and then the manufacturing cost of enterprise has been reduced.
In some embodiments, the step S11 includes:
and if the interruption time of the current spot welding is longer than a preset threshold value, taking the current spot welding as the first spot welding of the continuous welding of the next stage, and striking an arc at a first wire feeding speed.
The interruption time is the time from the completion of the previous spot welding and the start of the welding gun without welding current.
Specifically, in the continuous spot welding process, when the previous spot welding of the current spot welding is completed and the current spot welding is started, that is, when the welding machine is started, the time length from the completion of the previous spot welding to the completion of the current spot welding without welding current is greater than a preset threshold value, the current spot welding is used as the next stageAnd carrying out initial welding of continuous spot welding, wherein at the moment, arc striking is carried out at a first wire feeding speed. As shown in FIG. 2, t is the above-mentioned interruption duration, v1The first wire feeding speed is adopted for the first spot welding in the continuous spot welding process, and the interruption time t of the fourth spot welding is the first wire feeding speed3And if the welding speed is larger than the preset threshold value, taking the fourth-time spot welding as the first spot welding of the continuous spot welding of the next stage, and striking an arc at the first wire feeding speed.
In the embodiment of the application, the spot welding with the interruption time length larger than the preset threshold value is used as the first spot welding of the continuous spot welding of the next stage, the arc striking of the first spot welding is carried out at the first wire feeding speed, when the interruption time length is larger than the preset threshold value, the heat currently reserved by the welding wire does not reach the required value, the arc striking is possibly caused to fail by adopting the second wire feeding speed for the arc striking of the non-first spot welding, therefore, when the interruption time length of the current spot welding is larger than the preset threshold value, the first spot welding is used as the first spot welding of the continuous spot welding of the next stage, and the arc striking success rate of the current spot welding when the interruption time length is larger than the preset threshold value is increased.
In some embodiments, considering that the corresponding interruption durations of the welding wires made of different materials are different when the welding wires retain the same heat, the preset threshold of the interruption duration is set according to the material of the welding wire in the embodiment of the present application. When the interruption time is not more than the preset threshold value, the welding wire can retain certain heat, namely, when the first-time spot welding is used for arc striking at a second wire feeding speed which is higher than the first wire feeding speed, the success rate of arc striking cannot be influenced due to the acceleration of the wire feeding speed.
In some embodiments, the step S12 includes:
and if the interruption time of the current spot welding is not more than a preset threshold value, taking the current spot welding as the non-first spot welding of the continuous welding, and striking the arc at a second wire feeding speed.
Specifically, in the continuous spot welding process, if the interruption time of the current spot welding is not longer than the preset threshold value, that is, the welding gun is turned on, and the time from the completion of the last spot welding to the absence of the welding current is not longer than the preset threshold value when the current spot welding is started, at this time, the welding wire is still in a state of retaining a certain amount of heat,and taking the current spot welding as the non-first spot welding of the continuous welding, and striking the arc at a second wire feeding speed which is higher than the first wire feeding speed. As shown in FIG. 2, t is the above-mentioned interruption duration, v2At the second wire feeding speed, the second spot welding is performed for an interruption time t1Within a preset threshold value, the spot welding is used as non-first spot welding, arc striking is carried out at a second wire feeding speed, and the interruption time t is prolonged during third spot welding2And the arc striking speed is not more than the preset threshold value, so that the third spot welding is also used as the non-first spot welding, and the arc striking is carried out at the second wire feeding speed.
In the embodiment of the application, when the interruption time is not more than the preset threshold value, the welding wire still retains certain heat, so that the arc striking of non-primary spot welding is carried out at the second wire feeding speed, the arc striking success rate is ensured, and meanwhile, the arc striking speed is improved, so that the efficiency of continuous spot welding is improved.
In some embodiments, the welding control method further includes, before performing the continuous spot welding:
and A1, matching the corresponding first wire feeding speed and the second wire feeding speed according to the welding process parameters of the continuous spot welding.
Specifically, the welding process parameters include the type and specification of the weldment, the specification of the welding wire, the shielding gas, the welding specification, the welding position and the like, and the welding includes the welding current and the welding voltage. The wire feeding speed is higher than the melting speed due to the excessively high wire feeding speed in the spot welding process, and the unmelted welding wire is easily blown in sections, so that the formation of a welding seam is damaged, and the insufficient amount of filling metal is caused when the wire feeding speed is excessively low, so that undercut is easily formed, and the quality of the welding seam is influenced. Therefore, according to the welding process parameters of the continuous spot welding, the first wire feeding speed and the second wire feeding speed are matched correspondingly to carry out the continuous spot welding, and the success rate of arc striking and the quality of the continuous spot welding which are influenced by mismatching of the wire feeding speeds can be reduced. For example, according to the following welding process parameters: the weldment is wide 2cm, thick 1 cm's carbon steel strip of board, and the welding wire is diameter 0.8 mm's carbon steel, and protective gas is carbon dioxide, and the welding specification is: the welding current is 80A, the welding voltage is 18.5V, the welding position is flat welding (namely horizontal welding, the surface of a welding line is upward), and according to the welding process parameters, the preset corresponding first wire feeding speed is 3m/min, and the second wire feeding speed is 6 m/min. The second wire feeding speed is greater than the first wire feeding speed, and the preset first wire feeding speed can be set to a fixed value by a user, or set to a proportional value of the second wire feeding speed, for example, the first wire feeding speed value under the same welding condition is 30% of the second wire feeding speed.
In the embodiment of the application, the quality of spot welding can be influenced by the wire feeding speed in the arc striking and welding processes, so that the wire feeding speed and the welding process parameter in the continuous spot welding process are matched according to the preset corresponding first wire feeding speed and second wire feeding speed before the continuous spot welding is carried out, and the problem of reduction of the quality of the welding seam of the continuous spot welding caused by overhigh or overlow wire feeding speed is avoided.
In some embodiments, the welding control method further comprises, before striking an arc with the corresponding wire feed speed:
and B1, obtaining the welding condition of continuous spot welding.
Specifically, the welding conditions include a weldment, a specification of a welding wire, a welding voltage, a shielding gas, a second wire feeding speed, inductance parameters, and the like.
And B2, arc striking is carried out according to the corresponding arc striking parameters matched with the welding conditions.
Specifically, the arc striking parameters include arc striking current, arc striking duration, arc striking current rising rate and falling rate, arc striking current peak value, initial arc striking no-load voltage and the like. And matching corresponding arc striking parameters to strike arcs according to the acquired welding conditions. For example, the acquired welding conditions are: the weldment is carbon steel, the protective gas is 100% carbon dioxide, the specification of the welding wire is carbon steel with the diameter of 0.8mm, the second wire feeding speed is 6m/min, the inductance parameter is 0, and then the corresponding arc striking parameters are matched according to the welding conditions: the arc striking current is 400A, the arc striking duration is 3ms, the arc striking current rising rate is 800A/ms, the arc striking current falling rate is 1000A/ms, and the initial no-load voltage of arc striking is 50V.
In the embodiment of the application, arc striking is performed by matching corresponding arc striking parameters according to the obtained welding conditions of continuous welding, and because arc striking is performed by using the welding wire to ignite an arc, the size and duration of current required by the welding wire when the arc is ignited are different due to different materials and sizes of the welding wire, and the larger the diameter of the welding wire made of the same material is, the larger the required arc striking current is. Therefore, the possibility of arc starting failure can be reduced by matching the arc starting parameters according to the acquired welding conditions including the weldment, the specification of the welding wire, the second wire feeding speed and the like.
In some embodiments, the step B2 further includes:
and in the continuous spot welding process, if the welding condition is detected to be changed, re-matching the corresponding arc striking parameters according to the current welding condition to strike the arc.
Specifically, since welding conditions such as a weldment and a second wire feeding speed may change during continuous spot welding, if it is detected that one or more welding conditions of preset continuous spot welding change, arc striking needs to be performed by re-matching arc striking parameters corresponding to the welding conditions according to current welding conditions.
In the embodiment of the application, when the welding condition of the continuous spot welding is detected to change, the corresponding arc striking parameters are matched again according to the current welding condition for arc striking, so that after the welding condition is changed, the arc striking parameters corresponding to the changed welding condition can be adopted for arc striking, the condition that the fixed arc striking parameters are still adopted by different welding conditions in the continuous spot welding process is avoided, and the arc striking success rate of the continuous spot welding is increased.
In some embodiments, the welding control method further comprises, after striking the arc at the first wire feed speed or after striking the arc at the second wire feed speed:
and C1, judging whether the arc striking is successful according to the detection result whether the welding current is detected after the arc striking is finished.
And C2, after the arc striking is successful, welding at the second wire feeding speed.
Specifically, during arc striking, a welding wire is in contact with a weldment to form a short circuit, then the welding wire is pulled to strike an arc, and if the arc is successfully struck, welding current exists in an internal circuit of the welding machine. Therefore, whether the arc striking is successful or not can be judged by detecting whether the welding current exists in the internal circuit of the welding machine after the arc striking is finished, and the spot welding is carried out at the second wire feeding speed after the arc striking is successful.
In the embodiment of the application, welding is carried out after the arc striking success is determined, so that the welding of spot welding under the condition of unsuccessful arc striking is avoided, and the quality and the efficiency of continuous spot welding are influenced.
In some embodiments, the step C1 includes:
and if the feedback current exists in the internal circuit of the welding machine and the duration of the feedback current accords with the preset duration after arc striking is finished, judging that the arc striking is successful.
Specifically, whether feedback current with the size within a preset range exists in an internal circuit of the welding machine is detected through a current detector, and the duration of the feedback current meets the preset duration requirement, so that the fact that welding current exists in the welding machine can be judged, and the fact that arc striking is successful is indicated. The feedback current can be detected by adopting a current detector such as a current divider, a current Hall and the like in an internal circuit of the welding machine.
In some embodiments, after the arc striking is completed, when the arc striking is determined to fail, the arc striking is performed again. Specifically, the interruption duration of the spot welding which fails in the current arc striking can be judged again, if the spot welding is judged to be not the first spot welding, the arc striking is carried out again at the second wire feeding speed, or the spot welding which fails in the current arc striking can be directly used as the first spot welding of the continuous spot welding of the next stage, the arc striking is carried out at the first wire feeding speed, and the situation that the arc striking fails to occur again when the arc striking is carried out at the second wire feeding speed is avoided.
In the embodiment of the application, whether the feedback current meeting the preset requirement exists in the internal circuit of the welding machine is detected by adopting the current detector, so that whether the arc striking is successful or not can be judged as the arc striking is successful because the feedback current meets the preset size and duration, and the condition that the arc striking is not successful due to the unstable arc striking in the arc striking process but the welding current in a short time is possibly generated in the arc striking process so as to be misjudged as the successful arc striking is avoided.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

Because when the first spot welding, adopt lower wire feed speed, consequently, can improve this first spot welding's striking success rate, but when not first spot welding, because spot welding has been carried out before the non-first spot welding, the welding wire has kept certain heat, consequently, adopt the second wire feed speed that is greater than first wire feed speed to carry out the striking of non-first spot welding, not only can guarantee this non-first spot welding's striking success rate, also can improve the striking speed of non-first spot welding, thereby continuous spot welding efficiency has been improved, reduce the required time of continuous spot welding, and then the manufacturing cost of enterprise has been reduced.
