tungsten welding electrode:
1. It used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding.
2. In both processes the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas.
3. It used because it can withstand very high temperatures with minimal melting or erosion.
4. it made by powder metallurgy and are formed to size after sintering.
Feature
