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
