Tungsten Welding Rod 2.4

Tungsten is a rare metallic element used for manufacturing TIG (or GTAW) electrodes. The TIG process relies on tungsten’s hardness and high temperature resistance to carry the welding current to the arc, as it has the highest melting point of any metal (3,410 degrees Celsius). These non-consumable electrodes come in a variety of sizes and lengths and are composed of either pure tungsten or a hybrid of tungsten and other rare earth elements and oxides. Choosing an electrode for the TIG process depends on the base material type and thickness and whether you weld with alternating or direct current.
