Gas Metal Arc Welding Process Fundamentals • In GMAWthe welding heat sour~is an arc maintained­ between a consumable wire electrode and the workpiece • The weld is formed by melting and solidification ofthe joint edges togetherwith filler material transferred from the electrode • An flowofinert gas shields the high-temperaturearcand. Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. The two base materials are melted together forming a join. The gun feeds a shielding gas alongside the electrode helping protect the weld pool from airborne contaminants. Gas Metal Arc Welding Basics: Welding Current Welding Voltage. Introduction Gas metal arc welding (GMAW) is a welding process that has been commercially available for around 60 years. The basic operation of the GMAW process occurs when an electrical arc is established and maintained between a base material and a continuously feed wire electrode.

GMAW can be implemented as a manual, semi-automatic, or automatic process, and the flexibility offered by the various process variations is advantageous in many applications. GMAW provides a considerable increase in weld metal deposition rates compared to GTAW or SMAW, and when implemented as a semi-automatic process, less welder skill is typically required.

Gas 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 con-tinuously 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+ (reverse) polarity to the electrode.
