The Lanthanated Tungsten Electrode became very popular in the circle of welding in the world soon after it was developed because of its good welding performance. The electric conductivity of Lanthanated Tungsten electrode is most closed to that of 2%Thoriated Tungsten. Welders can easily replace Thoriated Tungsten Electrode with Lanthanated Tungsten Electrode at either AC or DC and do not have to make any welding program changes. The radioactivity form Thoriated Tungsten can thus be avoided. Another advantage of Lanthanated Tungsten is being able to bear high current and having the lowest burn-loss rate. This Electrodes are state patent products in our factory. (NO:ZL97100727.6)
Lanthanated Tungsten Electrode has the following advantages:
*Better Cutting Mechanical Properties
*better performance of creep resistant
*High temperature recrystallization
*Good tractility
