Thoriated tungsten electrode is used widely, it is generally used for DC electrode negative or straight polarity applications.
Thoriated tungsten electrode
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 arc easily and steadily. in addition, the gap of the breaking arc 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.
1.it contains 2% thorium oxide that is dispersed inside the whole length of the tungsten rod. it provides excellent resistance from weld pool contamination and offers the welder easier arc starting capabilities and more stable arc
2. color: red
3. diameter: 1.0-12mm
4. length; 150mm, 175mm
5. quality of surface: ground finish, polish finish
