TIG Welding (GTAW) Electrodes

In GTAW (Gas Tungsten Arc Welding) also known as TIG welding (Tungsten Inert Gas welding), a non consumable electrode (made up of Tungsten) is used. Tungsten is preferred due to high its high melting point (approximately 3,4100C) and high hardness. Either pure tungsten is used as electrode or it can be alloyed with other elements. …

Welding electrodes – Understanding the SMAW electrode symbols

Shielded Metal Arc Welding (SMAW) electrodes are designated by “E” followed by four (or five) digits for example: E7018, E6013 or E10018. I will explain the meaning of these symbols: IF THE ELECTRODE HAS “E” FOLLOWED BY FOUR DIGITS (FOR EX. E7018) E – Stands for electrode XX – first two digits designates the minimum …
