WWZirconiated

Class: EWZr
AWS: A5.12

Zirconium (ZrO2) = Contains small amount Zirconiated electrodes have welding characteristics that generally fall between those of pure and thoriated tungsten


Zirconiated electrodes are the tungsten electrode of choice for AC welding because of arc stability and starting characteristics of thoriated tungsten. EWZr-1 contains a small amount of Zirconium (Zr02) Has welding characteristics that generally fall between those of pure and thoriated tungsten
