The electrodes have deoxidizers that prevent oxidation, so you can weld multiple layers. Along with the wire electrode, a shielding gas is fed through the welding gun, which shields the process from … Arc Welding Process • In arc welding, a welding power supply is used to create an arc between the base metals (metals to be welded) and electrode. It is faster welding process. Yields high productivity. It is done by burning of fuel gases with the help of oxygen which forms a concentrated flame of high temperature. The melted part of welding plates diffused in one another and create a weld joint after cooling. Gas metal arc welding (GMAW) is a welding process where the heat is generated by an electric arc incorporating a continuous-feed consumable electrode that is shielded by an externally supplied gas. How is MIG Welding done? The gun also carries a shielding gas to the nozzle of the gun. ???????????? GMAW PowerPoint Presentation . Gas Metal Arc Welding.
