Ceriated tungsten electrodes for welding orbital tube,pipe ,small parts

Ceriated Tungsten Electrode is a non -radioactive material. It is known to be especially good for DC welding with low amperage because it starts very easily at low amps and usually requires about 10% less amps to operate than thoriated material.

Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to 2.20 percent cerium and are referred to as 2 percent ceriated. These electrodes perform best in DC welding at low current settings but can be used proficiently in AC processes. With its excellent arc starts at low amperages, ceriated tungsten has become popular in such applications as orbital tube and pipe fabricating, thin sheet metal work, and jobs involving small and delicate parts. 

Like thorium, it is best used to weld carbon steel, stainless steel, nickel alloys, and titanium, and in some cases it can replace 2 percent thoriated electrodes. Ceriated tungsten has slightly different electrical characteristics than thorium, but most welders can't tell the difference. 

Application

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 cannot 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.
