Thorium-Tungsten Electrode is widely used as an additive oxide electrode, having much more advanced comprehensive welding performance  than the  properties of pure tungsten electrode and other additive oxide electrodes. It can not be replaced by other oxide electrodes during the long using process . It can be operated easily, has a high current load and produces are easily and steadily. In addition , the gap of the breaking are is big , loss less and life longer. It has  higher recrystallizing temperature, better conductivity and mechanical cutting property . Now , Thoriated-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 .
