Resistance welding electrode:

 a combination of the advantages of tungsten wire and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, easy machining, and has features such as sweating Coolers, because of its high hardness of tungsten , melting point, anti-adhesion characteristics, are often used to make a certain wear resistance, high temperature welding, welding electrode.
