WELDING TORCH AND ALL-POSITION WELDING DEVICE

A welding torch (3, 3A, 3B) includes a gas lens (9) of a lattice structure that straightens a shielding gas. The welding torch (3, 3A, 3B) includes a non-consumable electrode (5, 5B), an electrode holder (7, 7B) into which the non-consumable electrode (5, 5B) is inserted, and a torch body (4) includ...

Zusammenfassung:	A welding torch (3, 3A, 3B) includes a gas lens (9) of a lattice structure that straightens a shielding gas. The welding torch (3, 3A, 3B) includes a non-consumable electrode (5, 5B), an electrode holder (7, 7B) into which the non-consumable electrode (5, 5B) is inserted, and a torch body (4) including a sleeve (44) that holds the electrode holder (7, 7B), a flow path forming portion (41) that forms a shielding gas flow path (51, 52) around the sleeve (44), and a nozzle (42) that forms a shielding gas guiding space (53) around a distal end of the non-consumable electrode (5, 5B), the distal end extending from the electrode holder (7, 7B), in which the gas lens (9) is provided so as to separate the shielding gas flow path (51, 52) from the shielding gas guiding space (53).
