WP20 Tungsten Welding Electrode: A Comprehensive Guide
Tungsten is a rare metallic element widely used in the manufacturing of Tungsten Inert Gas (TIG) electrodes. The TIG welding process relies on the exceptional hardness and high temperature resistance of tungsten to carry the welding current to the arc. With the highest melting point of any metal at 3,410 degrees Celsius, tungsten electrodes are ideal for withstanding the extreme conditions of welding.
