GMAW is an arc welding process. See related link.
GMAW welders work in production shops.
Quality and ease of mechanization are the factors that have led to the increased use of the GMAW process.

The main difference between Flux-Cored Arc Welding (FCAW) and Gas Metal Arc Welding (GMAW) is the type of consumable electrode used. FCAW uses a tubular electrode filled with flux to protect the weld pool, while GMAW uses a solid wire electrode with an external shielding gas. FCAW is often preferred for outdoor welding due to its self-shielding capabilities, while GMAW generally produces cleaner welds.

Argon is the most common gas used in gas metal arc welding.
Gas metal arc welding (GMAW) typically uses electricity as its power source. The electric current passes through a consumable wire electrode, creating an arc that melts the base metal and forms the weld. The electrode is continuously fed from a spool to maintain the welding process.
FCAW (Flux-Cored Arc Welding) wire contains a flux that generates shielding gas and slag during the welding process, which can be used in both indoor and outdoor environments. In contrast, GMAW (Gas Metal Arc Welding) wire is solid and relies on an external shielding gas to protect the weld from contamination, making it best suited for clean environments. Additionally, FCAW can be used on thicker materials and is often preferred for heavy-duty applications, while GMAW provides a cleaner weld and is typically used for thinner materials.

For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
