The process uses shielding from an externally supplied gas to protect the molten weld pool.

An external shielding gas is used to protect the molten weld puddle. The electrode used in gas metal arc welding is also the filler metal consumable. Gas metal arc welding ( GMAW ) is a fusion welding process, which uses an electrical arc as the source of energy that causes the metal fusion to occur.

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. Gas Tungsten Arc welding – (GTAW or TIG welding ) In this process, a tungsten electrode is used along with shielding gas to heat the filler metal that is placed closely on top of the base metals and an arc created due to the power supply welds the joints, while the gas protects the weld. In gas welding , fuel gases like acetylene, hydrogen are used to generate heat. 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.

This welding generates higher temperature than gas welding. Absolutely nothing to loose in cost and everything to gain in knowledge and application.

An electric arc is created between the tip of the wire and the weld pool. Shielding gas protects the weld from atmospheric contamination. MIG or (GMAW) is one of the most popular welding processes. In this process, consumable electrode is used in the form of wire and a shielding gas such as Argon, Helium, Carbon dioxide or a mixture of these gases are used.

These gases shield the molten weld pool from atmospheric contamination. As initially this process was used mainly for welding aluminium and stainless steels with inert gas shielding it is more popularly known as metal inert gas (MIG) welding. This is a comprehensive text on all aspects of the GMAW process. Gas Metal Arc Welding (GMAW) is also known as Metal Inert Gas Welding (MIG welding ). Hundreds of full-color illustrations are used to help describe the fundamentals of GMAW, metal transfer modes, equipment, electrode wires, shielding gas, and much more.

Topics include an introduction to welding technology, oxyfuel cutting techniques, and MIG welding techniques and processes. Since the joining is an inter-mixture of metals, the final weld joint potentially has the same strength properties as the metal of the parts. The variety of shielding gases used in arc welding can be a confusing topic. Learners will complete these welds and weldments conducted per AWS standards. The consumable bare wire is fed automatically through a nozzle into the welding arc by a wire-feed drive motor.

These courses can be offered concurrently as CEU courses. Use arc welders, gas welders, and gas torches to weld together metal components and alloys. T he GMAW process is a commonly used arc welding process.

As all other processes, it has its advantages and limitations.

The gas metal arc welding process, most commonly known as MIG, is one of the most used joining processes in the world today. The process had its beginnings over years ago, but it is still being improved every day.
