Tungsten Electrodes

 

Due to the characteristics of tungsten, it is very suitable for TIG welding and other electrode materials similar to this kind of work. Adding rare earth oxide to tungsten metal to stimulate its electron work, the welding performance of tungsten electrode can be improved: better arc starting performance, higher stability of arc column, less electrode burning rate. Common rare earth additives include ceria, lanthanum oxide, zirconia, yttrium oxide and thorium oxide.

 

    Characteristic

 

Tungsten electrode plays an important role in the arc starting, arc stability and welding quality. Under the action of high temperature of the arc, the quality loss of tungsten electrode occurs, which is called the ablation of tungsten electrode. In order to discuss the ablation mechanism of tungsten electrode, the ablation can be divided into two parts: adding oxide and tungsten itself.

 

Classification:

 

Cerium tungsten electrode

Lanthanum tungsten electrode

Thorium tungsten electrode

Zirconium tungsten electrode

Yttrium tungsten electrode

 

Measures to prevent radiation injury

 

1. Thorium tungsten electrode shall have special storage equipment, which shall be stored in iron box and equipped with exhaust pipe.

2. When welding with airtight cover, the cover body shall not be opened during operation. During manual operation, the air supply protection helmet must be worn or other effective measures shall be taken.

3. Special grinding wheel shall be provided for grinding thorium tungsten electrode. The grinding machine shall be equipped with dust removal equipment. The grinding debris on the ground of the grinding machine shall be frequently wet cleaned and intensively buried.

4. Wear dust mask when grinding thorium tungsten electrode. Wash hands with flowing water and soap after contacting thorium tungsten electrode, and wash work clothes and gloves frequently.

5. Select reasonable specification during welding and cutting to avoid excessive burning loss of thorium tungsten electrode.

6. Try not to use thorium tungsten electrode but cerium tungsten electrode or lanthanum tungsten electrode, because the latter two are not radioactive.
