Thoriated Tungsten Electrodes Properties

Thoriated Tungsten Electrodes Picture

Thoriated tungsten electrodes are made of tungsten doped with thorium, so that they can facilitate arc starting, increase arc stability, and have low electrode burning loss, free of slag and splashing, and long service.

Compared with pure tungsten electrodes, thoriated tungsten electrodes have lower functional electricity, higher crystallization temperature, better electricity conductivity and better cutting mechanical performance.

Thoriated tungsten electrodes are the most popular electrodes used in the world. Since they have better welding performance than pure tungsten electrodes, thus, they are widely used in direct current welding, especially under overload current, they can sill have a good performance.

Besides their good properties, the radioactivity of thoriated tungsten electrodes is paid much attention. Therefore, staff should be careful and keep airy.
