3.2 X 175mm Zirconium Tungsten TIG Electrodes (10 Sticks) WZR8-3.2 32WZ8

Tungsten zirconium WZR8

WZr – Tungsten zirconium
Applications: TIG welding (welding of Al and Mg alloys)

For the WZr alloy type, up to 0.8% by weight of
zirconium oxide is added to the tungsten powder.
The alloy is used almost exclusively for TIG
electrodes. Because of its low alloy content,
the material is suitable to welding compounds
whose welds must be free of foreign material.
Furthermore, the alloy can also be used for welding aluminum and magnesium using alternating
current. It stands out compared to WP due to a
more stable arc.

Principle of TIG welding

• Decisive factors
• Modern inverter power sources with HF ignition and accurate power setting
• Tungsten electrode: Size and composition
• Electrode preparation: Cut, angle, seat of tip
• Distance between electrode and workpiece, and distance between electrode tip and gas nozzle
• Shielding gas: Quantity, composition, gas backing where necessary
• Ambient conditions: Draft, extraction
