W electrode is a suitable for the tig welding and the other electrode material alike. To enforce the welding power of w electrode , we adding rare-earth oxide in the metal w..Such as cerium oxide, thorium oxide, lanthana, zirconia and yttriun oxide ect.
2% thoriated tungsten electrodes(EWTh-2) is the rare earth tungsten electrode which uses most early, is also the best tungsten electrode in welding performance until now , therefore, this tungsten electrode(EWTh-2) market share is globally highest, but because of the radioactive contamination in the powder metallurgy and the rolling process, European ,American developed countries limited to use the 2% thoriated tungsten electrodes(EWTh-2).because of its fine welding performance, its use has not been restricted. Thorium is a low-level radioactive material that primarily emits alpha particles as well as some beta and gamma radiation. However, if welding is to be performed in confined spaces for prolonged periods of time or if electrode grinding dust might be ingested, special precautions relative to ventilation should be considered. The user should consult appropriate safety personnel. So many users have switched to other alternatives. 2% thoriated tungsten electrodes are widely used because they make good welds and are long lasting and quite easy to use. A thoriated tungsten electrode operates at a temperature well below its melting temperature. this tungsten electrode is used primarily for DC welding and may split if used for AC welding Material welded is primarily Aluminum and Magnesium
All 2% thoriated tungsten electrodes is packaged 10 pieces of 150mm or 175mm.
Special diameters and lengths are available, please contact sales for inquiries.
E3 Tungsten Electrodes deliver superior arc starting, electrode lifetime, and overall cost effectiveness. Users of 2% thoriated tungsten can switch to E3 tungsten with
confidence. E3 requires fewer re-grinds and provides longer overall lifetime when compared to 2%
thoriated. E3 tungsten can be used on DC electrode positive or negative with a pointed end,
or balled for use with AC power sources.
Featues over Thoriated Tungsten
Lower operating temperature
Fewer re-grinds
Improved arc starting
Versatile use
