Abstract
An automatic welding apparatus for non-consumable-electrode-type arc welding comprises a mechanism which is adapted to feed a second wire in the molten pool and to oscillate this second wire in synchronism with the oscillation of the welding torch and the conventional wire and at a position where both wires are opposed to each other in an axis perpendicular to weld line. An automatic welding apparatus for consumable-electrode-type arc welding comprises a mechanism which is adapted to feed a second wire in the molten pool and to oscillate this second wire in synchronism with the oscillation of the welding torch and at a position where both wires are opposed to each other in an axis perpendicular to weld line.
