Fig. 2 is a flowchart illustrating a phase control method for twin wire welding according to an embodiment of the present disclosure. The methods provided by the embodiments of the present disclosure may be performed by any electronic device having computer processing capabilities, such as a micro-control unit. The phase control method for the twin-wire welding is applied to the twin-wire welding equipment with the front wire and the rear wire. As shown in fig. 2, the phase control method of the twin wire welding includes:
step S102, a first phase matching time in a standard state is obtained according to the set current of the front wire, the set current of the rear wire, a first peak time and a first matching coefficient, wherein the standard state is a state that the voltage of the front wire is unified voltage corresponding to the set current of the front wire, the first peak time refers to the peak time corresponding to the set current of the front wire, and the first matching coefficient is a preset first constant value.
And step S104, when the set current of the front wire and the set current of the rear wire are kept unchanged and the electrical parameters of the front wire or the rear wire meet the set adjustment conditions, determining the phase matching time corresponding to the current value according to the first phase matching time, the current value of the electrical parameters, the reference value and the set matching coefficient so as to adjust the electrical parameters.
In the embodiment of the disclosure, a new phase matching time is determined by obtaining a first phase matching time in a standard state and according to the adjustment requirements of electrical parameters of the front wire or the rear wire, namely, a current value before adjustment and a reference value after adjustment, so as to adjust the electrical parameters, thereby achieving the purpose of phase matching of the front wire and the rear wire, and further realizing voltage stability control during double-wire welding and improving double-arc welding quality.
Wherein the electrical parameter does not comprise the set current because the set current of the front filament and the set current of the rear filament need to be kept constant. In the disclosed embodiments, the electrical parameters may be a set voltage, an average peak voltage, and an average current.
Similar to the first matching coefficient, the set matching coefficient in the embodiment of the present disclosure is a constant value obtained empirically.
In the embodiment of the present disclosure, before welding, in step S102, a first phase matching time in a standard state needs to be determined; during the welding process, in step S104, it is necessary to adjust the phase matching timing in real time.
Specifically, in step S102, the standard state indicates that the set voltage of the front wire corresponding to the set current of the front wire is a unified voltage, and the actual welding current of the front wire is consistent with the set current. At this time, the first phase matching time T can be calculated according to the peak time corresponding to the set current of the front wire, the set current of the rear wire and the first matching coefficientPhase1The calculation formula is as follows:
wherein, IbFor setting the current of the rear filament, IaFor the set current of the front wire, T12aIs the first peak time, K1To calculate a first matching coefficient at a first phase matching instant.
In step S104, when adjusting the phase matching timing in real time, it is first determined whether the set voltages of the front wire and the rear wire are unified voltages when the set currents are not changed, and if so, the phase matching timing does not need to be adjusted for the set voltages, and if not, the phase matching timing is adjusted for the set voltages.
Specifically, when the phase matching time is adjusted for the set voltage, the corresponding electrical parameter is the set voltage, and the adjustment condition is that the set voltage is not equal to an integrated voltage corresponding to the set current of the front wire or the rear wire.
When the set voltage of the front wire or the rear wire changes, if the set voltage is larger than the unified voltage, the arc length is lengthened, the molten drop is enlarged, and the falling time moves backwards. If the set voltage is less than the unified voltage, the arc length is shortened, the molten drop is reduced, and the falling time moves forward. Since the drop falling timing is changed, the phase matching timing should be readjusted.
In the process of adjusting the phase matching time, when the set voltage of the front wire is not equal to the unified voltage corresponding to the set current of the front wire, determining a second phase matching time T according to the first phase matching time, the set voltage of the front wire, the unified voltage corresponding to the set current of the front wire and a set second matching coefficientPhase2(ii) a When the set voltage of the rear wire is not equal to the unified voltage corresponding to the set current of the rear wire, determining a second phase matching time T according to the first phase matching time, the set voltage of the rear wire, the unified voltage corresponding to the set current of the rear wire and a set second matching coefficientPhase2。
Second phase matching time TPhase2The calculation formula of (2) is as follows:
wherein SetVbFor setting the voltage of the rear filament, BaseVbFor a unified voltage, SetV, corresponding to the set current of the rear filamentaFor setting voltage of front filament, BaseVaFor a unified voltage, K, corresponding to the set current of the front filament2To calculate a second matching factor for the second phase matching instant.
The standard value BaseIPV of the peak voltage of the front wire and the rear wire is changed due to the change of the set voltage of the front wire and the rear wireaAnd BaseIPVbCorresponding adjustments are also made. Specifically, the standard value BaseIPV of the peak voltage of the front wire and the adjusted peak voltage of the rear wirea_adjAnd BaseIPVb_adjThe calculation formula of (a) is as follows:
during welding, the arc length may change due to external disturbances, such as changes in dry elongation and changes in welding power supply parameters, and at this time, the average value of the actual peak voltage, i.e., the average peak voltage, may change. When the arc length is longer, the peak voltage is higher, the molten drop is larger, the drop is moved backwards, and when the arc length is shorter, the peak voltage is lower, the molten drop is smaller, the drop is moved forwards. At the moment, in order to ensure the stability of the two electric arcs in the double-wire welding, the phase matching moment is adjusted along with the change of the peak voltage.
In step S104, the phase timing may be re-matched according to the deviation of the average peak voltage of the front and rear wires from the standard value of the peak voltage.
Specifically, when the phase matching time is adjusted for the average peak voltage, the corresponding electrical parameter is the average peak voltage, and the adjustment condition is that the average peak voltage is not equal to the reference voltage of the front wire or the rear wire, where the reference voltage of the front wire or the rear wire is the voltage corresponding to the first phase matching time or the second phase matching time.
In the process of adjusting the phase matching time, when the average peak voltage of the front wire is not equal to the reference voltage of the front wire, determining a third phase matching time T according to the phase matching time corresponding to the reference voltage of the front wire, the average peak voltage of the front wire, the reference voltage of the front wire and a set third matching coefficientPhase3(ii) a When the average peak voltage of the rear wire is not equal to the reference voltage of the rear wire, determining a third phase matching time T according to the phase matching time corresponding to the reference voltage of the rear wire, the average peak voltage of the rear wire, the reference voltage of the rear wire and a set third matching coefficientPhase3。
Here, if the set voltage of the front wire or the rear wire is equal to an integrated voltage corresponding to the set current of the front wire or the rear wire, the reference voltage of the front wire or the rear wire is the set voltage of the front wire or the rear wire.
At this time, the third phase matches time TPhase3The calculation formula of (2) is as follows:
wherein, AvgIPVbAverage peak voltage of rear filament, BaseVbFor setting voltage of rear filament, AvgIPVaIs the average peak voltage of the front filament, BaseVaFor setting voltage of front filament, K3To calculate a third matching coefficient for a third phase matching instant.
If the set voltage is not equal to the unified voltage corresponding to the set current of the front wire or the rear wire, the reference voltage of the front wire or the rear wire is the standard value BaseIPV of the adjusted peak voltagea_adjAnd BaseIPVb_adj。
At this time, the third phase matches time TPhase3The calculation formula of (2) is as follows:
wherein, AvgIPVbAverage peak voltage of rear filament, BaseIPVb_adjIs the standard value of the adjusted peak voltage of the rear filament, AvgIPVaIs the average peak voltage of the front filament, BaseIPVa_adjIs the standard value of the adjusted peak voltage of the front filament, K3To calculate a third matching coefficient for a third phase matching instant.
During the welding process, changes in dry elongation inevitably occur. When the dry elongation is longer, the average current is smaller, the drop falls off and moves forward, and when the dry elongation is shorter, the average current is larger, the drop falls off and moves backward; therefore, when the actual average current changes, the phase matching time is adjusted along with the change of the average current in order to ensure the stability of the two arcs in the double-wire welding.
In step S104, the phase timing may be re-matched according to the deviation of the average current of the front and rear wires from the set current.
Specifically, when the phase matching time is adjusted for the average current, the corresponding electrical parameter is the average current, and the adjustment condition is that the average current is not equal to the set current of the front wire or the rear wire.
In the process of adjusting the phase matching time, when the average current of the front wire is not equal to the set current of the front wire, determining a fourth phase matching time T according to the phase matching time corresponding to the set current of the front wire, the average current of the front wire, the set current of the front wire and a set fourth matching coefficientPhase4(ii) a When the average current of the rear wire is not equal to the set current of the rear wire, determining a fourth phase matching time T according to the phase matching time corresponding to the set current of the rear wire, the average current of the rear wire, the set current of the rear wire and a set fourth matching coefficientPhase4。
Third phase matching time TPhase4The calculation formula of (2) is as follows:
wherein, AvgAbAverage Current of the rear filament, SetAbFor setting current of rear filament, AvgAaAverage Current of the front filament, SetAaFor setting current of front filament, K4To calculate a fourth matching coefficient at a fourth phase matching instant.
In the embodiment of the present disclosure, the power supply of the front wire may be set as a main power supply, and the power supply of the rear wire may be set as a secondary power supply, and after step S104, a rear wire control signal may be generated according to the phase matching time corresponding to the current value, so as to control the working power supply output of the rear wire.
Through actual welding verification, the technical scheme of the embodiment is adopted, and the phase matching is proper and the welding is good in a standard state. When disturbance occurs outside, such as set voltage change, peak voltage change and actual average current change, the phase automatic matching time is appropriate, the response speed is high, the interference between the two arcs is small, the arcs are stable, and the welding quality is good.
According to the phase control method for the double-wire welding, the phase matching time is adjusted under different adjusting conditions, so that the phase matching of the front wire and the rear wire is guaranteed, the voltage stability control during the double-wire welding is realized, and the double-arc welding quality is improved.
Fig. 3A shows a phase time matching diagram in a standard state, and fig. 3B shows a phase time adjustment diagram when external disturbance occurs, where the phase time matches with a corresponding forward shift and a backward shift according to the magnitude of the external disturbance. Wherein a represents the anterior filament, b represents the posterior filament, TPhase1The time instants are matched for the first phase. T isPhase + andTPhase-representing the phase matching instant increase and decrease, respectively.

step S410, determine a standard phase matching time.
Step S421, determining whether the set voltage is not equal to a unified voltage; if so, go to step S422, otherwise, go to step S431.

In step S423, it is determined whether the matching is completed, if so, step S431 is performed, and if not, step S422 is not performed.
Step S431, determining whether the average peak voltage is not equal to the standard value of the adjusted peak voltage; if yes, go to step S432, otherwise go to step S441.
Step S432 adjusts the phase matching timing.
Step S433, determining whether the matching is completed, if yes, executing step S441, otherwise, executing step S432.
Step S441, determining whether the set voltage is not equal to a unified voltage; if yes, go to step S442, otherwise, end the process.
In step S442, the phase matching timing is adjusted.
In step S443, it is determined whether the matching is completed, if yes, the process is ended, and if not, no step S442 is executed.
According to the overall processing flow chart of the voltage-controlled rectifier circuit, firstly, under a standard state, the phase matching time is calculated, then whether the set voltage is consistent with the unified voltage or not is judged, if the phase matching time is inconsistent, adjustment is carried out, then whether the peak voltage changes or not is judged, if the phase matching time is changed, adjustment is carried out, finally, whether the actual average current is consistent with the set current or not is judged, the actual average current is inconsistent with the set current or not is judged, and the phase time is adjusted.
