The thorium tungsten electrode contains thorium oxide (Th02 or thorium oxide). It is the most common tungsten electrode in the United States and has become a standard for judging other tungsten electrodes. However, because of the radioactive pollution in the process of powder metallurgy and rolling grinding, the production of this kind of electrode is restricted in Europe and America, but because of its excellent welding property, its use is not limited.
Cerium tungsten electrode is one of the earliest non radioactive tungsten electrode products in China. It can be used as a non radioactive tungsten electrode instead of thorium tungsten. Tungsten oxide electrode made by adding rare earth cerium oxide in tungsten base by powder metallurgy and rolling grinding and polishing process.
The difference between thorium tungsten electrode and cerium tungsten electrode
1. Thorium tungsten electrode is radioactive, while cerium tungsten electrode is not radioactive
2. Thorium tungsten electrode is the main chemical composition of tungsten and thorium oxide, and cerium tungsten electrode inside the main chemical components are tungsten and cerium oxide
The specifications and models of the two electrodes are in agreement with the surface.
