Which statement is NOT an advantage of FCAW?

• A. Slag must be removed
• B. High deposition rates
• C. High quality weld metal
• D. Easy to use in various positions

Answer: (A)

Slag removal is not an advantage of FCAW. The flux core creates a protective slag on the weld that must be chipped away after welding. That cleanup step adds time and a potential for defects if slag isn’t fully removed, so it isn’t considered a benefit. The other points reflect real advantages: FCAW typically offers high deposition rates, thanks to the continuous filler metal and efficient heat input; it can be used in various positions due to a stable arc and forgiving nature with joint fit-up; and it can produce good weld metal quality when the right flux and shielding conditions are used.
