Thoriated Tungsten Electrodes

Thoriated Tungsten Electrodes

Containing minimum of 97.30% tungsten and 1.70% to 2.20% thorium, thoriated tungsten electrode has good overall performance, especially suitable for bearing the overload current. It is the most commonly used electrode in America and some other countries. With very high temperature resistance and minimal consumption or erosion features, thorium tungsten electrodes are widely used for DC welding of carbon steel & stainless steel, nickel alloys and titanium mental, etc. However, due to its slight radioactive hazard, the applications of thoriated tungsten electrode are limited in some extent.

Thorium tungsten electrode is recommended to store in steel boxes, labelled with the radiation warning sign.

1. Workers should be encouraged to wash their hands before using the toilet facilities;
2. When conducting the thoriated tungsten electrodes, workers should better wear mouth, nose and eye protections.
3. Workers must always follow the manufacture warnings, instructions and the MSDS (Material Safety Data Sheet).

Packing and Shipping:
We deliver thoriated tungsten electrodes by ocean shipping or air transportation. We can provide several packaging as following pictures:
