Abstract
PURPOSE: To make high-grade shielding gas amount minimum required and improve working efficiency at the maximum sheilding effect by spouting plural kinds of shielding gases in superposed layer form from the nozzles of a torch.
CONSTITUTION: Where arc is being generated between a welding wire 20 and the work A, shielding gas such as Ar or the like is sent into the pipe rod 3 of a torch body 2 through the first gas hose 13 and is exhausted into the cavity part a1 of the first nozzle 8 of a torch head part 12 through a vent hole 4, thence from the end port 8a it is blown to the weld zone of the work A by enclosing the arc. On the other hand, shield gas such as CO2 or the like is supplied into a cover 9 through the second gas hose 14 and is blown to the work A through the cavity a2 of the second nozzle 11 by enclosing the first shielding gas from the end port 11a. At this time, three or more kinds of shielding gases may be used. Thereby, the maximum shielding effect is provided and the production of spatter prevented.
