WT20 Thorium Tungsten Electrode
Thorium-Tungsten Electroe 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 electrode. 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 arc easily and steadily. In addition,the gap of the breaking arc is big. It has higher recrystallizing temperature,better conductivity and mechanical cutting property. Now Thorium-Tungsten Electrode is widely used in welding carbon steel,stainless,nickel alloy and titanium metal. It becomes the first selection material for high quality welding
