Product Detail

       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.

       The shape of tungsten electrode tip is an important factor for TIG.

       Characteristics of 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.

       Tungsten electrode plays an important role in tungsten argon arc welding of arc, arc stability and welding quality.

       Applications of tungsten electrode:

       Tungsten electrode is used for inert gas protection arc welding, plasmacutting, spray-coating and furnace melting.

       Surface conditions of tungsten electrode:
Grinding, cleaning, electrolysis polishing, drawing or forging.
