What does the acronym MIG stand for?

Manual Inert Gas
Metal Inert Gas
Metallic Inert Gas
Methane Inert Gas

The correct answer is: Manual Inert Gas

The correct answer is B. Metal Inert Gas. MIG welding, also known as Gas Metal Arc Welding (GMAW), uses a continuously fed wire electrode and a shielding gas to create the weld. The process is called Metal Inert Gas welding because it uses a shielding gas (often a combination of argon and CO2) to protect the weld pool from atmospheric contamination. The other options are incorrect: A. Manual Inert Gas - This is not the correct term for MIG welding. MIG welding is typically done with a semi-automatic or automatic welding process. C. Metallic Inert Gas - This is not the correct term for MIG welding. The process involves melting and fusing metal, not gases. D. Methane Inert Gas - Methane is not typically used as a shielding gas in welding processes like MIG welding.
