Abstract
Abstract An electrode suitable for the TIG welding process, in which the welding arc produced by contact-less ignition between the tip of the electrode and the workpiece burns within an inert gas atmosphere and the application of the weld material is effected by a separately guided welding rod. In order to optimize the startability, the tungsten electrode has a thorium oxide content of 2-4% and a thorium-oxide particle size of 6-12 mu m.
