Tungsten Electrode Guide
As the TIG process becomes more popular-there have been questions on which type of Tungsten Electrode to use based on the application. Here is a guide from Weldcote Metals that can help.
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 current (AC) or direct current (DC). Each electrode is color-coded to eliminate confusion over its type. The color appears at the tip of the electrode.
Contact us today for any questions you may have about choosing the correct Tungsten Electrode. Northern Gases stocks the Pure (GREEN) and 2% Thoriated (RED) in different sizes but we can also order other types and sizes available from the chart.
