High quality Ceriated Tungsten electrode WCe20 Grey Tip tungsten rod for DC welding with low amperage

Ceriated Tungsten Electrodes have good starting arc performance and keep arc easily at a low current. It commonly used in the pipe, stainless steel products and welding of small precision parts.

Cerium oxide is added tungsten, cerium production of tungsten electrodes. Specific data in the following table: Grade dopant doping amount other doping electron work function color coating head WCe20 CeO2 1.80 ~ 2.20%<0.20% 2.7 ~ 2.8 gray tungsten cerium has the following advantages over the tungsten thorium materials: 

* non-radiative 

* low melting rate of long life 

* good welding arc resistance. 

Therefore, tungsten, cerium is the best substitute for low current welding environment tungsten thorium. 

Application

Cerium tungsten electrode is mainly used in low current DC welding. Cerium tungsten at low current arc has a very good performance, and thus become the most rail pipe welding equipment manufacturer's standard, in addition, it can also be used for other low-current applications such as precision small parts welding. Cerium tungsten is not suitable for use under high current conditions, since under such conditions, the oxide will quickly move to the high heat region, i.e., the tip electrode welding zone, so that the uniformity of the oxide of the damage, so the oxidation uniform distribution of these benefits was brought will cease to exist.
