Zirconiated tungsten electrodes (AWS classification EWZr-1) contain a minimum of 99.10% tungsten and .15 to .40% zirconium. A Zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. It is ideal for AC welding as it retains a balled tip and has a high resistance to contamination. Its current carrying capability is equal to or greater than thoriated tungsten. Under no circumstances is zirconiated recommended for DC welding.
Trade mark | Added impurity | Impurity quantity | Other impurities | Tungsten | Electric discharged power | Color sign |
WZ8 | ZrO2 | 0.70 - 0.90% | <0.20% | The rest | 2.5 - 3.0 | White |
Application: Zirconiated Tungsten is most commonly used for AC welding of aluminum and magnesium alloys.
