 The Yttrium Tungsten Electrode has good welding performance under AC conditions and has good corrosion resistance. Especially in the case of high load currents, the superior performance exhibited by the tantalum tungsten electrode is irreplaceable for other electrodes. When welding, the end of the zirconium-tungsten electrode can be kept in a spherical shape to reduce the phenomenon of tungsten penetration, and is suitable for welding of magnesium-aluminum and other alloys under AC conditions.
