Abstract

ABSTRACT TITLE.: ARC WELDING METHOD There is prov ided an arc welding method for performing welding in a spray transfer manner by oscillating a welding current while feeding a weld wire. The welding current is oscillated from the time when it is determined that a transition state at the start of an arc is terminated and the arc is formed in a normal state. The oscillation of the welding current is repeated such that a first welding current Iw1, a second welding current Iw2, and a third welding current Iw3 are applied during a first period, a second period, and a third period, respectively, wherein 0<Iw2<Iw3<Iw1.
