Abstract
In an arc welding control method for controlling welding in which a material of a base material is a galvanized steel sheet, a feed speed of a welding wire is alternately switched between a forward feed period and a reverse feed period, and a short circuit period and an arc period are repeated, during the arc period, a first arc period Taduring which a first arc current Iais applied, a second arc period Taduring which a second arc current Iais applied, and a third arc period Taduring which a third arc current Iais applied are switched over time, and it is controlled so as to be Ia>Ia>Ia. Constant voltage control is performed during the second arc period Ta, and constant current control is performed during the first arc period Ta
