Cerium Tungsten Electrode

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.
