The use of an inert gas like argon or a mixture of argon and carbon dioxide results in a clean, spatter-free weld with good visibility. Gas Metal Arc Welding (GMAW/MIG) Gas Metal Arc Welding (GMAW), commonly called MIG (Metal Inert Gas) welding, is a semi-automatic or fully automatic welding process types that uses a continuously fed wire electrode and a shielding gas to protect the weld pool.
MMA Welding Process Types and Their Specific Techniques
Manual Metal Arc (Shielded Metal Arc Welding) Manual Metal Arc (MMA), also known as Shielded Metal Arc Welding (SMAW) or stick welding, is one of the most ubiquitous and versatile welding process types. Variations and Filler Materials Within GMAW, variations exist based on the gas mixture.
Advantages and Typical Applications of MMA Highly portable and requires minimal equipment, typically just a power supply and a rod holder. Gas Tungsten Arc Welding (TIG/GTAW).
MMA Welding Process Types and Techniques Explained
Excellent for welding in difficult positions, including vertically overhead and in confined spaces. Welding is the high‑temperature process of joining metals by melting the base material and, often, a filler metal to create a permanent bond.
