Cerium Tungsten Electrode
Description
2% cerium tungsten electrode, which is also known as WC electrode, contains a minimum of 97.30% tungsten and 1.80 to 2.20% cerium. It performs optimally in DC welding in the low current environment but can be used proficiently in AC or DC processes.
To meet different customers' needs, we are able to provide various kinds of wolfram cerium electrodes with different content of cerium.
Application
Cerium tungsten electrode has become popular in such applications as orbital tube and pipe manufacturing, thin sheet metal work or jobs where small and delicate parts are welded by virtue of its excellent arc starts at low amperages. Like thorium, this cerium tungsten electrode is most appropriate for welding carbon and stainless steels, nickel alloys and titanium, making it an ideal replacement for 2% thoriated electrodes.
Advantages of Cerium Tungsten Electrode
1. Non-radiation
2. Low melting rate
3. Long welding life
4. Good arc resistance
Features of Cerium Tungsten Electrode
Cerium tungsten is slightly different in electrical characteristics from thorium but most operators are not able to tell the difference. And it is recommended to use cerium tungsten electrodes at lower amperages. If in higher amperage situations, the oxides will migrate quickly to the heat at the tip, removing the oxide content and nullifying its process benefits.
Notes
Cerium tungsten electrode is not suitable for applications under high current condition, because under that condition the oxides will rapidly migrate to the heat zone, namely the top of the electrode welding point, which will damage the evenness of the oxides.

Packaging and Transportation
We normally pack ten cerium tungsten electrodes in a plastic box with mark and several boxes in a plywood case by sending them via ocean or air.
Established in 2008, Shanghai TallKee Refractory metals specializes in producing various types of tungsten products, like tungsten rod, tungsten powder, tungsten electrode, etc. Above is some description of one category of tungsten electrode, called cerium tungsten electrode ( WC electrode). If you are interested in this product, please enter our website and learn more. We have many types for your reference.
- Pure Tungsten ElectrodePure tungsten electrode can be manufactured with black surface, polished surface or ground surface. It is normally marked with green. This kind of electrode is firstly used when welding argon arc. This is also called TIG tungsten electrode. But under DC welding condition...
