Abstract

A method is provided for controlling arc welding including forward and reverse feeding periods alternately switched. By the method, a set of a short circuit period and an arc period is repeated, and the arc welding is controlled such that the reverse feeding period (Tr) shifts to the forward feeding period when an arc occurs during the reverse feeding period (Tr), and that the forward feeding period shifts to the reverse feeding period (Tr) when a short circuit occurs between the welding wire and the object during the forward feeding period. The reverse feeding period (Tr) includes a reverse feeding deceleration period (Trd) having a time length that is adjusted in accordance with the time length of the short circuit period.
