Abstract
An arc welding method is described where pulse arc welding is performed with a welding wire being fed in a forward direction during a first period and short-circuit transfer arc welding is performed with the welding wire being fed in the forward direction and a reverse direction during a second period. The arc welding method alternately switches between the first period and the second period, where the switching of the first period to the second period is performed during a peak period of the pulse arc welding.
