Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings.

The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
Referring to fig. 1, after arc breaking occurs in conventional fixed-time spot welding, in some application scenarios of spot welding, when arc striking and wire breaking occur during spot welding, a part of welding wire flies out to cause less filler metal, and the phenomenon of unsaturated abnormal welding spots is obviously different from that of normal welding spots. The welds of the anomalous spots 3, 5, 7 in figure 1 become significantly smaller.
Referring to fig. 2, there are also short welds that are welded at a faster rate, and the welding torch is moved over the weld. When arc breaking occurs, the filling metal is reduced, but the welding speed is not changed, so that the welding seam at the arc breaking position becomes thin. The weld of the anomalous weld 2 shown in figure 2 is significantly thinner.
FIG. 3 shows a flowchart of a weld formation compensation method in an embodiment of the present disclosure. The method provided by the embodiment of the disclosure can be executed by an electronic device with computing processing capability in a welding device.
As shown in fig. 3, the weld forming compensation method includes the following steps:
s302, according to the abnormity detected in the welding process of the welding equipment, the welding type of the current welding point is obtained, wherein the welding type comprises spot welding and short welding.
Wherein, welding equipment can detect whether the abnormal conditions such as broken arc appear. For example, the collection of the arc signal is converted into a pulse signal, and when the arc break occurs, the pulse signal is obviously different from the pulse signal of the normal welding state. The current signal during welding can also be adopted, and the current signal can also change after arc breaking.
The welding type of the current welding spot has relevant information in the system of the welding device, and the welding gun specifies the welding type of the current welding spot before welding. The welding type of the current welding point is obtained from an execution instruction in the system, and is used for adopting an applicable compensation mode aiming at different welding types in the subsequent steps. The weld spots and the weld joints have reduced filler metal after arc interruption, and the reduced filler metal needs to be compensated in some way.
S304, if the welding type of the current welding spot is spot welding, compensating the welding time for the welding spot according to the loss of the welding spot in the abnormal time period.
The spot welding means that the electric arc welding stays on a welding spot for a fixed time according to a preset time, and a welding gun can move to the next point after spot welding of one point is completed. During spot welding, the workpiece is pressed to be in close contact with the workpiece, then current is switched on, the contact position of the workpiece is melted under the action of resistance heat, and a welding spot is formed after cooling.
The consumption is the amount of metal that needs to be filled to complete the weld joint weld under normal welding conditions. The amount of wear is then the amount of metal filling that the solder joint has reduced during soldering compared to the amount consumed under abnormal conditions.
After the calculation based on the loss amount, the time needed to compensate is further obtained. Spot welding process the welding gun is not moved until the welding is completed, and the amount of metal filled in the welding spot can be increased by compensating for the welding time.
S306, if the welding type of the current welding spot is short welding, reducing the welding speed to compensate the welding spot according to the moment when the welding spot is recovered to be arc.
Among them, short welding is different from spot welding in that a welding gun moves during welding, and it is difficult to compensate for a reduced filling amount by a compensation time. During short welds, compensation for the weld can be achieved by reducing the welding speed.
In the embodiment, the welding spot with abnormal conditions can be automatically compensated, and the consistency and the performance of the welding spot are improved. The compensation mode can be adopted according to different welding types, compensation welding is adopted for spot welding, welding speed is adjusted for short welding, and compensation of filling quantity can be realized for different types.
Time
Fig. 4 shows a state after the automatic compensation process is performed after the arc breaking occurs in the fixed-time spot welding, and the abnormal welding spots 3, 5, and 7 basically maintain the welding results consistent with other welding spots.
Fig. 5 shows a state after the automatic compensation processing is performed after the arc breaking condition occurs in the welding mode of the short welding, and the abnormal welding point 2 basically maintains the welding result consistent with other welding points.
As shown in fig. 6, in an embodiment, in step S304, if the welding type of the current welding spot is spot welding, a specific implementation manner of compensating the welding time for the welding spot according to the loss amount of the welding spot in the abnormal time period includes:
s602, arc breaking time and arc burning time of the welding equipment in abnormal conditions are monitored.
The arc breaking time and the arc burning time need to be recorded in the monitoring process, and the arc breaking time and the arc burning time after the arc breaking are re-recorded and are applied to subsequent loss calculation.
S604, determining the loss of the welding spot in the abnormal time period according to the instruction functions of the arc breaking time, the arc burning time and the wire feeding speed in the abnormal time period.
Wherein, fig. 7 shows a normal fixed time spot welding wire feeding sequence chart, each spot welding process comprises a slow wire feeding speed, a climbing speed, a main welding speed and a burn-back speed, and the welding time of the spot welding is T in total. When abnormal conditions such as wire breakage or unsmooth wire feeding occur in the spot welding process, the wire feeding speed instruction is still carried out according to the time sequence in the figure 6, and no welding wire is filled into the molten pool during the actual arc breaking period.
Fig. 8 shows a timing chart of an abnormal fixed-time spot welding wire feeding, T2 indicates a period of time when an arc interruption occurs, wherein a indicates an arc interruption time and b indicates an arc burning time. No wire is filled into the molten pool during the T2 process, and the shaded portion corresponding to the T2 represents the loss of welding filler during the T2 period. The instruction function of the wire feeding speed is a relation function of the wire feeding speed and the wire feeding time sequence, and the loss can be obtained by calculus solving in an abnormal time period based on the instruction function of the wire feeding speed.
At T2The loss A actually exists in a time period, the loss can be obtained by calculus solving in an abnormal time period based on the instruction function of the wire feeding speed, and the specific calculation process is as follows:
a ═ (lower limit a, upper limit b) f (x) dx;
wherein, A represents the loss amount, the loss amount represents the filling amount of the welding spot reduced in the abnormal time period, a represents the arc breaking time, b represents the arc burning time, and f (x) represents the command function of the wire feeding speed.
And S606, determining the compensation time required to be added by the welding spot in the welding process according to the loss and the main welding value of the wire feeding speed.
Wherein, the time period T4 in FIG. 8 is the required compensation time, T4＝A/V0. Wherein, T4Represents a compensation time; v0A primary weld value representing wire feed speed. The welding time compensation is performed before the burn-back stage, so that the calculation process of the compensation can be simplified, and the processing time on a welding spot can be reduced.
After the compensation time is compensated to the welding time of the welding spot, the welding time of the abnormal welding spot is T1+T2+T3+T4+T5。
In the embodiment, on the basis of monitoring the arc breaking time and the arc burning time, the loss amount is obtained by utilizing the wire feeding timing diagram and the calculus, the compensation time is obtained based on the loss amount, the obtained compensation time is accurate, and the welding spot obtained after the obtained compensation time is compensated is basically consistent with the normal welding effect.
As shown in fig. 9, in an embodiment, in step S304, if the welding type of the current welding spot is spot welding, a specific implementation manner of compensating the welding time for the welding spot according to the loss amount of the welding spot in the abnormal time period further includes:
and compensating the determined compensation time to the welding time of the welding spot.
After the required compensation time is obtained, the compensation time needs to be added to the welding time of the welding point through the control process of the electronic equipment. For example, the compensation time can be added to the weld time of the weld point by program instructions.
As shown in fig. 10, in an embodiment, in step S306, if the welding type of the current welding spot is short welding, a specific implementation manner of compensating the welding spot by decreasing the welding speed according to the moment when the welding spot resumes the arc welding includes:
s1002, reducing the welding speed of the welding equipment to t% of a set speed, and detecting whether arcing occurs in a first time period.
In short welding, after arc breaking is monitored, the walking speed of a welding gun, namely the welding speed, is reduced to t% of a set speed. For example, if the set speed for normal short welding is V, the welding speed needs to be reduced to V × t%. After the welding speed is reduced, the arc-broken position of the welding line can stay for a long time, so that the compensation of the filling amount is realized.
If normal arcing is detected in the first stage, the process proceeds to step S1003, where the welding speed is returned to the set speed for normal welding, and if not, the process proceeds to step S1004.
the range of t% is any value between 0 and 100%, and different choices can be made according to the conditions of different welding points. The duration of the first period may be any value from 0.1 to 1000ms, and the duration setting of the first period may be related to t%, the welding speed, the filling amount of the weld, the wire feed speed, and the like.
And S1004, if the arc burning is not recovered in the first time interval, reducing the welding speed to zero to wait for the arc burning, and detecting whether the arc burning is performed in the second time interval.
Wherein if arcing has not been detected within the first time period, if compensation continues at a welding speed of V x t%, there may be a problem of insufficient compensation, requiring a further reduction in welding speed.
If arcing is detected within the second period of time, the welding speed needs to be restored to the set speed at the time of normal welding. If not, then proceed to step S1006.
In this embodiment, arc is waited for by reducing the welding speed to zero. The second period is calculated from the moment when the welding speed drops to zero, and the duration of the second period may be any value between 0.1 and 1000 ms. The duration setting of the second period of time may also be associated with t%, welding speed, weld fill, and wire feed speed, among others.
S1006, if the arcing is not detected in the second time period, a warning signal is sent.
And when the arcing is not detected in the second time period, the abnormal condition that the self-recovery cannot be realized occurs, the welding equipment automatically stops and gives an alarm, and the normal high-speed welding is recovered after the manual maintenance.
