Abstract
A plasma welding torch that can be reduced in size more than in conventional cases. When an inert gas G such as argon gas is supplied to an outer circumferential space around a non-consumable electrode, a portion of the inert gas G is used as plasma gas GP that forms a plasma arc PA between the non-consumable electrodeand a base materialvia a plasma orifice. A plasma welding torchmoves, maintaining this state, in the direction of the arrow shown in FIG.. Meanwhile, a portion of the inert gas G supplied to a gas flowing partis not used as the plasma gas GP but is used as shielding gas GS and is ejected onto the base materialahead in the welding direction via a shielding orifice. The welding on the base materialis performed in a state where the plasma arc PA and the base materialare shielded from the air by this shielding gas.
