Baoji Refractory Metal Developer Co.,Ltd is one of the leading China thoriated electrodes manufacturers and suppliers, and as a professional company we have productive factory, welcome to wholesale thoriated electrodes products from us.
Thoriated tungsten electrodes
It is widely used as an additive oxide electrode,it has much more advanced comprehensive welding property than the properties of pure tungsten electrode and other additive oxidde electrodes.It is not replaced by other oxide electrodes during the long use process.It can be operate easily and electric current load is big,it can produce arc easily and steadily,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 a first selection material for high quality welding.
