Which statement best describes a characteristic of FCAW compared to SMAW?

• A. FCAW typically achieves higher deposition rates than SMAW
• B. FCAW uses no shielding gas
• C. FCAW produces no slag
• D. FCAW cannot operate in all positions

Answer: (A)

FCAW generally achieves higher deposition rates than SMAW. This comes from using a continuously fed wire electrode and flux that provides shielding, which allows the arc to be maintained with fewer interruptions and enables higher travel speeds and current. In practice, this means more filler metal is deposited per hour compared to the stick electrode used in SMAW, boosting productivity. The other statements aren’t universal truths: some FCAW wires are self-shielded and need no external shielding gas, while others do use shielding gas; FCAW flux forms slag, so it isn’t true that it produces no slag; and FCAW can be operated in various positions with the right setup, so it isn’t correct to say it cannot operate in all positions.
