Tungsten electrode is the earliest used rare earth tungsten electrode, and it is also the best tungsten electrode type with the best welding performance. Therefore, the tungsten electrode market share of the variety is the highest in the world, but Because the tungsten-tungsten electrode is radioactively contaminated during powder metallurgy and calendering, its use is not limited due to its excellent solderability.

Thorium Tungsten electrode preparation method
Thorium Tungsten electrode preparation method is to first form tungsten powder by isostatic pressing after high temperature sintering, and then rotate the tungsten rod blank through the rotary forging equipment. After forging, an electrode product is produced by means of a grinding machine.
