Abstract

PURPOSE: To prevent the generation of lack of fusion and satter by inclining the wire guide of a torch with its lower side forward with respect to the welding advance direction, advancing a wire in the welding advance direction when directing the same downward and retreating the same when directing it upward thereby performing welding.
CONSTITUTION: A wire is fed with deformation in waveform into the narrow groove disposed in a harizontal position, and pulse MIG welding is carried out while the leading end of the wire is changed of directions upward and downward. At this time, a wire guide 7 of a torch 1 is inclined by an angle α with respect to the welding advance direction W by bringing its lower side forward. Hence, the position 5 of the leading end of the wire advances in the direction W when the wire directs downward and advances in a diagonal saw tooth shape when the wire directs upward.
