Tungsten electrode WL15 are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications.
Tungsten electrode WL15 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 tungsten electrode WL15 is most closed to that of 2%Thoriated Tungsten electrode.
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 electrode can thus be avoided.
