| 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.

and W. electrode: add lanthana in the mental W.
The advantages of La and W electrode:
The better mechanical cutting
The better anti- creep
Higher temperature in second crystallization
Better extensibility |

LA and W. electrode has been welcomed
in the world, especially the kind of electrode containing 1.5%La
and W. According to scientific research , this one is the nearest
to Th and W electrode in the conductivity,so the welding technicians
can change the electrode easily ,without changing the equipment
parameter.
