Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. 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 a repetitive description thereof 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 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 the arc breaking situation occurs in the conventional fixed-time spot welding, under some application scenarios of spot welding, when an arc striking and wire breakage phenomenon occurs in the spot welding process, a part of welding wires fly out to reduce filling metal, and the phenomenon of incomplete abnormal welding spots is obviously different from that of normal welding spots. The welds of the abnormal welds 3, 5, 7 as in fig. 1 are significantly smaller.
Referring to fig. 2, there are also short welds where the welding speed is high, where the welding gun is moving over the weld. When the arc breakage and the like occur, the filling metal is reduced at the moment, but the welding speed is not changed, so that the welding seam at the arc breakage is thinned. The weld of the abnormal weld 2 as shown in fig. 2 is significantly thinned.
FIG. 3 illustrates a flow chart 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 calculation processing capability in a welding device.
As shown in fig. 3, the weld seam formation compensation method includes the steps of:
s302, acquiring the welding type of the current welding spot according to the abnormality detected by the welding equipment in the welding process, wherein the welding type comprises spot welding and short welding.
Wherein, welding equipment can detect whether abnormal conditions such as arc break appear. For example, the acquisition of an arc signal is converted into a pulse signal, which is significantly different from the pulse signal of a normal welding state when an arc break occurs. 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 is provided with relevant information in a system of the welding equipment, and the welding gun has clear the welding type of the current welding spot before welding. The welding type of the current welding spot can be obtained from an execution instruction in the system and used for adopting an applicable compensation mode for different welding types in a subsequent step. The reduction of filler metal at the weld spot and weld joint occurs after arc interruption, and the reduced filler metal needs to be compensated in some form.
S304, if the welding type of the current welding spot is spot welding, compensating the welding time of the welding spot according to the loss of the welding spot in the abnormal period.
The spot welding means that the arc welding stays on the welding spot for a fixed time according to a preset time, and a welding gun can move to the next point after the spot welding of one point is completed. During spot welding, the workpiece is pressed to be in close contact, then current is conducted, the contact part 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 solder joint welding under normal welding conditions. Then, the amount of wear is the amount of metal filling of the spot during the welding process that is reduced compared to the amount of wear under abnormal conditions.
Further time to compensate is obtained after the calculation based on the loss. The welding gun is not moved before the welding process is completed, and the metal filling amount of the welding spot can be increased by compensating 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 resumes arcing.
Wherein, unlike spot welding, the welding gun moves during welding, and it is difficult to compensate for the reduced filling amount by compensating time. In the short welding process, the compensation of the welding seam can be realized by reducing the welding speed.
In the embodiment, the welding spot with abnormal conditions can be automatically compensated, and the consistency and performance of the welding spot are improved. The compensation mode can be adopted according to different welding types, the compensation welding is adopted for the point welding, the welding speed is adjusted for the short welding, and the 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 fixed-time spot welding has occurred the arc breaking condition, and the abnormal welding spots 3, 5, 7 are maintained substantially in conformity with the welding results of the other welding spots.
Fig. 5 shows a state after the automatic compensation process is performed after the arc interruption condition occurs in the welding mode of the short-circuit welding, and the abnormal welding spot 2 basically maintains the welding result consistent with other welding spots.
As shown in fig. 6, in one embodiment, if the welding type of the current welding spot is spot welding, step S304 includes, according to the loss amount of the welding spot in the abnormal period, compensating the welding time for the welding spot, including:
s602, monitoring arc breaking time and arcing time of abnormal conditions of the welding equipment.
The arc breaking time and the arcing time need to be recorded in the monitoring process, and the time when arc breaking occurs and arcing is re-performed after arc breaking is applied to subsequent loss calculation.
S604, determining the loss of the welding spot in the abnormal time period according to the arc breaking time, the arcing time and the instruction function of the wire feeding speed in the abnormal time period.
Fig. 7 shows a timing chart of normal fixed-time spot welding wire feeding, wherein each spot welding process comprises a slow wire feeding speed, a climbing speed, a main welding speed and a backfiring speed, and the total welding time of spot welding is T. When abnormal conditions such as wire breakage or wire feeding unsmooth occur in the spot welding process, the wire feeding speed command is still performed according to the time sequence in fig. 6, and no welding wire is filled into the molten pool during the actual arc breakage.
Fig. 8 shows an abnormal fixed-time spot welding wire feeding timing chart, T2 refers to a period in which an arc break occurs, a in the chart represents an arc break time, and b represents an arcing time. During T2, no welding wire is filled into the molten pool, and the shaded part corresponding to T2 represents the loss of welding filling in the period of T2. 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 solving calculus of the instruction function of the wire feeding speed in an abnormal period.
At T 2 The loss quantity A actually exists in the time period, the loss quantity can be obtained based on calculus solving of an instruction function of the wire feeding speed in an abnormal time period, and the specific calculation process comprises the following steps:
a= ≡ (lower limit a, upper limit b) f (x) dx;
wherein A represents the loss amount, namely the filling amount of the welding spot reduction in the abnormal period, a represents the arc breaking moment, b represents the arcing moment, and f (x) represents the instruction function of the wire feeding speed.
S606, determining the compensation time required to be increased in the welding process of the welding spot according to the loss and the main welding value of the wire feeding speed.
Wherein, the period T4 in FIG. 8 is the required compensation time, T 4 ＝A/V 0 . Wherein T is 4 Representing a compensation time; v (V) 0 Representing the main welding value of the wire feed speed. The weld time compensation can simplify the calculation process of the compensation before the burn-back stage, and can also reduce the processing time on the weld spot.
After compensating the compensation time to the welding time of the welding spot, the welding time of the abnormal welding spot is T 1 +T 2 +T 3 +T 4 +T 5 。
In the embodiment, on the basis of monitoring the arc breaking moment and the arcing moment, the loss is obtained by utilizing the wire feeding timing diagram and the calculus, the compensation time is obtained based on the loss, the obtained compensation time is accurate, and the welding spot after the obtained compensation time is compensated is basically consistent with the normal welding effect.
As shown in fig. 9, in an embodiment, if the welding type of the current welding spot is spot welding, step S304 further includes, according to a specific implementation manner of the loss amount of the welding spot in the abnormal period, compensating the welding time for the welding spot:
and compensating the determined compensation time to the welding time of the welding spot.
After the compensation time is obtained, the compensation time is increased to the welding time of the welding spot through the control process of the electronic equipment. For example, the compensation time can be added to the welding time of the weld spot by a program instruction.
As shown in fig. 10, in one embodiment, step S306, if the welding type of the current welding spot is short welding, is to reduce the welding speed to compensate for a specific implementation of the welding spot according to the moment when the welding spot resumes the arcing, including:
s1002, reducing the welding speed of the welding equipment to t% of a set speed, and detecting whether arc burning occurs in a first period.
In short welding, after arc interruption is detected, the running speed of the welding gun, namely the welding speed, is firstly reduced to t% of the set speed. For example, if the set speed in normal short welding is V, the welding speed needs to be reduced to v×t%. After the welding speed is reduced, the welding line stays at the arc breaking position of the welding line for a long time, so that the filling amount compensation is realized.
If normal arcing is detected in the first stage, it is necessary to proceed to step S1003, to restore the welding speed to the set speed at the time of normal welding, and if not, it is necessary to proceed to step S1004.
the t% range is any value between 0 and 100%, and can be selected differently according to the conditions of different welding spots. The duration of the first period of time may be any value from 0.1 to 1000ms, and the duration setting of the first period of time may be associated with t%, the welding speed, the filling amount of the weld, the wire feed speed, and the like.
And S1004, if the arcing is not recovered in the first period, reducing the welding speed to zero waiting for arcing, and detecting whether the arcing is generated in the second period.
Wherein if no arcing has been detected within the first period, if the compensation continues with a welding speed of V x t%, there may be a problem of insufficient compensation, requiring a further reduction in the welding speed.
If arcing is detected within the second period, it is necessary to restore the welding speed to the set speed at the time of normal welding. If not then it is necessary to proceed to step S1006.
In this embodiment, by reducing the welding speed to zero, the arcing is awaited. 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 from 0.1 to 1000 ms. The duration setting of the second period of time may also be associated with t%, welding speed, weld fill level, wire feed speed, etc.
S1006, if arcing is not detected within the second period, a warning signal is sent.
When no arcing is detected in the second period, abnormal conditions which cannot be recovered automatically occur, the welding equipment automatically stops and alarms, and normal high-speed welding is recovered after manual overhaul.
