Abstract
A gas shielded arc welding method in which a non-consumable electrode and a filler wire are respectively connected to independent DC power sources and the non-consumable electrode is located in a preceding position, feeding the filler wire from behind the electrode. The non-consumable electrode is held in a forwardly tilted position to form an angle smaller than 85.degree. with a workpiece, and the non-consumable electrode and filler wire are applied with inverse electric currents to thereby control the arc direction for formation of sound joints. A welding apparatus is also disclosed which is capable of effecting arc extension control and oscillation simultaneously.
