Abstract
There is provided an arc welding control method of alternating feeding of a welding wire between forward feeding and reverse feeding periodically according to a feeding rate pattern constituted of a forward feeding amplitude, a reverse feeding amplitude, a forward feeding period and a reverse feeding period, stored in correspondence to an average feeding rate setting value, and generating short-circuiting periods and arc periods to perform welding. An average feeding rate of the welding wire is detected, and at least one of the forward feeding amplitude, the reverse feeding amplitude, the forward feeding period or the reverse feeding period is changed so that the detected average feeding rate equals the average feeding rate setting value, thereby automatically correcting the feeding rate pattern.
