Abstract

The disclosure provides a welding pulse control method, device and welding machine control device. The welding pulse control method includes: outputting the welding current at a preset voltage for welding, so as to control the waveform of the welding current to appear a short-circuit point; the ratio of the time interval between two adjacent short-circuit points to the average period of the welding current exceeds the preset When setting the value, the function group is determined according to the ratio; the current peak adjustment amount, the peak time and the current base value adjustment amount are determined according to the ratio and the function group; according to the current peak adjustment amount, the peak time and the The adjustment amount of the current base value adjusts the welding current until the ratio is smaller than the preset value. The welding pulse control method provided in the present disclosure can automatically adjust the welding current, realize one-pulse-one-drop welding, and improve welding quality.

Description

technical field [0001] The present disclosure relates to the technical field of electric welding machines, in particular, to a welding pulse control method and device. Background technique [0002] Pulse MIG shielded welding is more and more popular among users due to its excellent welding performance, good operability and all-position welding. The droplet transfer methods of pulse welding can be divided into three types, including one-pulse-one-drop, multi-pulse-one-drop and one-pulse-multiple-drop. Generally speaking, pulse welding with one pulse one drop (one pulse forms one droplet) has the best welding effect, less welding spatter, easy to control, and the best weld shape. The situation of multiple pulses and one drop is more common, and the welding effect is also the worst. The reason for multi-pulse one drop is due to the difference in pulse welding conditions used by users. For example, the quality of welding wire used by some users is poor, that is, there are larg...
