With its special property, the mental W. is suitable for the TIG welding and the other electrode materials alike. To enforce the welding power of W electrode by adding rare-earth oxide in the mental W., the property of W can be improved greatly , with better electrode arc ,more stability of arc column, and less burning loss of electrode . The usual rare-earth annexing agents include the following: cerium oxide, thorium oxide, lanthana , zirconia and yttrium oxide ect.

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.
