Germanium tungsten electrode
Tungsten welding electrode has excellent welding performance, great arc starting capacity with good arc stability, low electrode burning loss, long service life, free of slag and splashing and high welding quality.
Brief introduction:
Tungsten has high melting point, strong electron emission ability, high elastic modulus and low vapor pressure, so tungsten electrode was used as thermal electron emission material early.
