The MCAW process uses the same equipment as which process?

• A. SMAW
• B. GTAW
• C. FCAW
• D. OAW

Answer: (C)

The main idea here is that Metal-Cored Arc Welding uses the same basic setup as Flux-Cored Arc Welding. Both are arc welding methods that rely on a continuously fed wire electrode and a shielding system, all powered by a welding power source. In MCAW you feed a metal-core wire through a MIG-style gun via a wire feeder with drive rollers, a contact tip, and the appropriate shielding (gas or self-shielding depending on the wire). The hardware—power source, wire feeder, torch, and gas system—is essentially the same as FCAW, with the only difference being the type of filler metal inside the wire. Other processes use different tooling: SMAW uses a stick electrode and holder, GTAW uses a TIG torch with a separate filler rod, and OAW relies on a flame torch and fuel gases, not a wire feeder.
