WTh(Thorium- Tungsten Electrode)
It 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 use process. It can be operated easily and current load is high .It can produce arc easily and steadily ,and the gap of the breaking arc is big ,loss less and long life .It has much higher recrystallizing temperature, much better conductivity and better mechanical cutting property .It is used for welding carbon steel, stainless steel, nickel alloy and titanium metal. It is the first selection material for high quality welding.
