Effective on a wide range of metals, including structural steel, stainless steel, and cast iron. "MIG" typically implies an inert gas shield, while "MAG" (Metal Active Gas) uses a mix of argon and active gases like CO2, which provides deeper penetration and higher welding speeds for carbon steel.

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. This process is the workhorse of high-volume manufacturing, such as automotive assembly lines, due to its speed, ease of automation, and ability to weld thin materials effectively.
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. 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.

The primary challenge for the welder is to concentrate this heat precisely where needed without excessively heating the surrounding area, which can weaken the metal or cause distortion. It utilizes a consumable electrode coated in flux, which generates a protective gas and slag layer when an electric current is struck.
