The gas metal arc welding process is also known as which of the following?

• A. MIG welding
• B. Flux cored arc welding
• C. Self-shielding process
• D. Shielded metal arc welding

Answer: (A)

Gas Metal Arc Welding (GMAW) uses a continuously fed solid wire electrode and shielding gas to protect the weld as the arc forms between the wire and the workpiece. The term widely used for this process is MIG welding, which is why it’s the best answer here. MIG welding specifically refers to this gas-shielded, wire-fed method. Flux-cored arc welding involves a flux-filled wire and can be either self-shielded or gas-shielded, so it’s not the same as the standard gas-metal-arc process. The self-sh shielding variant describes FCAW-S, which again uses flux for shielding, not external gas. Shielded metal arc welding is the stick welding process (SMAW), which uses a flux-coated electrode and no shielding gas.
