Abstract
PURPOSE: To reduce the pure inert gas consumption in the captioned welding by using pure inert gas for cutting-off electrode from the outside air and using crude inert gas or carbonic acid gas for protecting molten pool and arc from the outside air.
CONSTITUTION: Inert gas such as pure Ar gas is used as shielding gas for cutting- off an electrode 5 from the outside air within the inner nozzle 2 of a double shielded TIG welding torch and crude Ar gas or carbonic aicd gas is used as the shielding gas for protecting molten pool and arc from the outside air within an outer nozzle 3. In this way, the amount of using pure Ar gas is reduced and the welding cost reduced.
