Low Hydrogen electrodes are very popular in the industries because of the following reasons; Ability to produce X-ray quality welds Good weld bead appearance Ability to weld thicker material with high deposition rates Less susceptible to failures and cracks especially Hydrogen Induced Cracks Sound weld metal properties with good toughness A smooth, stable and quiet …
The selection of right welding electrodes is a quite challenging job because we need to consider many factors while choosing the best alternative. In this article, we will discuss the various factors responsible for choosing the right welding electrode for the Shielded Metal Arc welding Process (SMAW) for Carbon steels. The Shielded metal arc welding …
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. …
GMAW (MIG welding) electrodes are designated by some letters and numbers such as ER70S-6, ER90S-6 and E308L etc. I will explain the meaning of these symbols: FOR CARBON STEEL OR MILD STEEL (SUCH AS ER70S-6 OR ER70S-3) Where, ER – Designates electrode or filler rod XX – Designates the minimum tensile strength of the deposited …
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 …
