Abstract
The welding method according to the present invention is adapted to carry out a welding operation by feeding a welding wire to a material to be welded, and generating an arc between the material to be welded and welding wire, in which the welding is done with the welding wire feeding speed increased and reduced during the welding operation, the welding wire feeding speed being reduced after the occurrence of short-circuiting is detected, the welding wire feeding speed being increased after the cancellation of the short-circuiting and the transfer of the welding operation to the formation of the arc are detected.
