EN ISO CODE:
EWTh-2 is a Non consumable alloyed tungsten electrode with 2% Thorium, easier the arc initiation, arc stability and having ability to withstand very high temperatures, even those of welding arc. The presence of thorium increase the electrical characteristics by making the tungsten slightly more emissive. Presence of thoria increase the life of electrodes & increase the resistance to tungsten contamination. EWTh-2 commonly used for joining of ferrous materials.
