The wire feed and arc voltage are typically set by the machine, allowing the operator to focus on guiding the gun along the joint. Core Principles and Heat Sources All welding process types rely on a common principle: applying sufficient energy to melt the edges of the materials being joined, allowing them to fuse as they cool.

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. Advantages and Typical Applications of MMA Highly portable and requires minimal equipment, typically just a power supply and a rod holder.
Effective on a wide range of metals, including structural steel, stainless steel, and cast iron. The specific welding process types available allow fabricators to select the optimal method based on material, thickness, environment, and required quality, making a thorough understanding of these variations essential for any professional in metalworking.

It utilizes a consumable electrode coated in flux, which generates a protective gas and slag layer when an electric current is struck. 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.
