PURPOSE: To increase deposition quantity and to reduce welding heat input by stabilizing fusion of filler wire without effect of peculiarity of wire in the wire filling MIG welding method.
CONSTITUTION: By oscillating a comsumable electrode 1 in the direction vertical to weld line in 5-50Hz and single vibration, the generating point of arc is widened and welding is executed with filling a filler wire 2 from the front of vibrating face. In the case the relative position between the consumable electrode 1 and filler wire 2 is varied due to peculiarity of wire, the filler wire is surely melted, as a result, increase of deposition quantity and reduction of welding heat input are made possible, further, welding quality such as increase of efficiency at welding position and reduction of weld deformation, etc., is improved. Also, different kind wires can be simultaneously fused, it is effective for composition adjustment of weld metal.
