Cerium Tungsten Electrode are added in the rare-earth cerium oxide powder metallurgy and rolling mill, after throwing the production process from the tungsten electrode products are produced in our country the first non-radioactive tungsten electrode products, the features of the product are at low current conditions have good starting arc performance, a smaller-dimensional arc current. Therefore, it commonly used in the pipe, stainless steel products and welding of small precision parts. At low current DC or electrode diameter under the conditions at 2.0mm below cerium thorium tungsten electrode tungsten electrodes are the preferred alternatives.
throated tungsten electrode:WT20
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.
