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.

WZr electrode

WZr electrode: Add Zr(zirconia) in the mental W.
WZr electrode posses the best welding property under ac current. (alternating current),especially in the high loaded current, no other electrode can substitute it. In welding, the end portion of WZr electrode can maintain the ball shape

to decrease the leaking of W and posses better resistance to corrosion. Nowadays another replacement is Wla electrode.
