Due to the characteristics of tungsten, making it very suitable for TIG welding and other similar work of this electrode material. The addition of rare earth oxides to the metal tungsten to stimulate its electron work function, making the tungsten electrode welding performance can be improved. Tungsten electrodes include pure tungsten electrodes, lanthanated tungsten electrodes, thoriated tungsten electrodes, yttrium tungsten electrodes, and zirconiated tungsten electrodes.
