Abstract

PURPOSE:To prevent the change of properties during welding by forming the protecting film composed of the oxides of the specific metals on the outside surface of the plasma welding electrode except the electron radiating part at the end. CONSTITUTION:A heat-resistant and corrosion-resistant protecting film 3 composed of oxides of metals such as Al and Zr is formed on the outside surface of a plasma welding electrode 1 by such a method as sputtering and the end part 2 is polished to expose. This protecting film enables the change of properties owing to arc heat at the welding and the aloying accompanied with the deposition of the flying molten drops of the welding works to be prevented and reduces the consumption of the electrode.
