[0008] However, when the pulse period of the master and the slave is quite different, if the pulse period of the slave is forced to be consistent with the master, the actual current of the slave will be very different from the set current. Even if the compensation is performed, the required welding state cannot be achieved, which seriously affects the welding performance

The invention relates to the technical field of welding, and provides a current control method and device for double-wire pulse welding, electronic equipment and a storage medium. Two welding power sources are involved in the double-wire pulse welding. The current control method comprises the steps that a first welding current and a second welding current of the two welding power sources are obtained respectively; the ratio of a pulse period of the second welding current to a pulse period of the first welding current is obtained; and according to the ratio, the pulse ratio of the first weldingcurrent to the second welding current is controlled, so that the difference value of the pulse ratio and the ratio is smaller than a preset value, and the pulse of the first welding current and the pulse of the second welding current are output in a staggered mode. The pulse ratio of output of the two welding currents is adjusted along with the ratio of the pulse periods of the two welding currents, so that the actual pulse period of the welding currents is close to the set pulse period, the optimal welding state is achieved, and the stable welding effect is achieved.
Description
technical field [0001] The present disclosure relates to the field of welding technology, in particular, to a current control method, device, electronic equipment and storage medium for twin-wire pulse welding. Background technique [0002] figure 1 The composition structure of twin-wire welding is shown. Twin-wire welding is composed of two power supplies 11 (master and slave), two wire feeders 12, and two welding torches 13. The two power supplies 11 have a communication function. [0003] Twin-wire welding in pulse gas shielded welding is more and more widely used due to its large deposition efficiency, high welding speed, stable welding process and good welding performance. Especially for welded parts with long straight welds on medium and thick plates, the efficiency of double wire welding can be more than twice that of ordinary single wire welding. [0004] However, twin wire welding also has obvious disadvantages. refer to figure 1 As shown, since the distance bet...
