WT electrode for the TIG welding

The mental Th and W electrode

The mental TH and W electrode: add thorium anhydride in the mental W.
The advantages of TH and W electrode:
The lower power of electronic
The higher temperature of second crystallization
The better electro-conductive nature
The good property of mechanical cutting


Make Adulterant Doping amount Color marker
WT10 ThO2 0.9-1.20% yellow
WT20 ThO2 1.80-2.20% red
WT30 ThO2 2.80-3.20% purple
WT40 ThO2 3.80-4.20% orange

The mental TH and W electrode: is a kind of universally used material of W, with a far perfect property than the pure W. and it is widely used in the DC welding. It is easily handled and widely used in many company nowadays even if under the overload current ,being regarded as one portion of high welding quality.
During the using of Thoriated tungsten, the effect of electricity saving is obvious, the argon amperage could be reduced 20-50%.And because of the welding amperage is low, splat is difficult to see during the welding, the head of Thoriated tungsten is also difficult to become round, the time of using is more longer.
Keep good air condition and properly deal with the wasted welding material.
