Electrode for a welding torch for tungsten gas-shielded welding and welding torch having such an electrode

摘要

The present invention relates to an electrode (200) for a welding torch (100) for tungsten gas-shielded welding, in particular for tungsten inert gas welding or for plasma welding, wherein the electrode (200) comprises at least one insert (210) composed of a material (211) different from the electrode material (201), wherein the insert (210) at least partially forms an arc-side surface (202) of the electrode, the electrode (200) has, on the arc-side surface thereof, a plurality of focusing-gas bores (220) for supplying a focusing gas (222) for focusing an arc (120), and the electrode (200) has at least one axially extending gas removal bore (230) for removing a gas (132) from the arc-side surface (202) of the electrode (200) through the axially extending gas removal bore (230).
