WTZIRC8093 XTRweld 0.8% Zirconiated Tungsten Electrode, 3/32, White, 10 Piece
Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
APPLICATIONS
- Zirconiated tungsten electrodes (AWS classification EWZr-8) contain a minimum of 98.60 percent tungsten and 0.7 to 0.9 percent zirconium. A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. It is ideal for AC welding because it retains a balled tip and has a high resistance to contamination. Its current-carrying capability is equal to or greater than that of thoriated tungsten. Under no circumstances is zirconiated recommended for DC welding.
