Product Description
Description: Thorium Tungsten Electrodes
Thoriated tungsten electrode contains 0.8%-4.2% thorium oxide, its electron work function is 2.7eV.Arc to be easier, electric arc stable. It performs well with overload current, so it’s widely used in various TIG and PAW. Thorium oxide has strong current carrying capacity, high recrystallization temperature, better conductivity, stronger mechanical cutting performance and longer service life. When welding, the tip of thoriated tungsten electrode keeps sharpening so that the ball on the tip of tungsten electrode can be not easy to crack at a greater degree of assurance. Now, Thorium-tungsten electrode is widely used in welding carbon steel, stainless steel, nickel alloy and titanium metal. It becomes the first selection material for high quality welding.
