The tungsten electrode has the high-melting point, low-arc ignition, good-arc stability and non-consumable characteristics. The tungsten electrode added 0.15-4% ThO2, CeO2, La2O3, ZrO2, which can reduce the burn-off rate of electrode. As a result, the tungsten electrode are prolonged their service life.
Application for Manufacturer Tungsten Electrode
1. Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding.
2. Both the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas.
3. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion.
4. Tungsten electrodes are made by powder metallurgy and are formed to size after sintering.
