Thoriated tungsten electrode contains 0.8% - 4.2% thorium oxide. Its electron work function is 2.7eV. easy arc formation and stable electric arc. It performs well with overlaod current, therefore it's widely used in various TIG and PAW. Thorium oxide has a strong current-carrying capacity, high recrystalization temperature, better conductivity, stronger mechanical cutting performance and longer service life. When welding, the tip of the tungsten electrode keeps sharpening so that the ball on the tip of the tungsten will not be easily crack. Now, it is widely used in welding carbon steel, stainless steel, nickel alloy and titanium metal. It has become one of the first selection macterial for high quality welding.
