WebGas Metal Arc Welding (GMAW), by definition, is an arc welding process which produces the coalescence of metals by heating them with an arc between a continuously fed filler metal electrode and the work. The process uses shielding from an externally supplied gas to protect the molten weld pool. The application of GMAW generally requires DC+ ... WebPrinciple. An arc welding process using a continuous hollow electrode filled with a flux which provides shielding gases, deoxidisers, alloy additions and slag formers. Some cored electrodes are designed to be used with an additional gas shield which is usually carbon dioxide or a carbon dioxide rich gas mixture.
