摘要：Disclosed is a consumable electrode arc welding in which short-circuit welding isperformed by alternating short-circuits and arcs while a welding wire is fed automatically.In this method, a short-circuit state and an arc state are alternately generated by feedingthe welding wire in periodically alternating forward and backward directions at apredetermined frequency and a predetermined velocity amplitude with reference to abasic wire feed speed based on a set current. The speed of periodic feeding of thewelding wire is controlled in such a manner that the waveform to feed the welding wire isdifferent between the forward and backward directions.
