Thoriated Tungsten Electrodes WT40
The thoriated tungsten electrodes WT40,Thorium oxide content of which is 4%, the electrodes specifications for Ø2.4 mm X150 mm.Thorium tungsten electrode is simple,Even in the current overload can also work well, there are still many companies use this material，it is regarded as part of the high quality of welding.
Even so,People gradually turned to other types of tungsten electrode.For example, the cerium tungsten and tungsten lanthanum.This is not just because they are in most applications have demonstrated excellent performance, but more importantly they have no radiation damage.Because thorium oxide in thorium tungsten electrode will produce trace amounts of radiation,The welding personnel would not close to them.
