Abstract
A welding torch includes a torch body including a flow path forming portion that forms a shielding gas flow path into which an inert gas flows and an outer gas flow path communicating with the shielding gas flow path, a first gas lens that straightens the inert gas in the shielding gas flow path and blows the inert gas out as a shielding gas, and a second gas lens that straightens the inert gas in the outer gas flow path and blows the inert gas out as an outer gas. Provided is an all-position welding device that performs butt welding of tubes, and includes the welding torch and a rotation mechanism for rotating the welding torch around the tube.
