Compared with SMAW, FCAW has which advantage?

• A. Higher deposition rates than SMAW
• B. Requires more pre and post weld cleaning
• C. Only suitable for ferrous materials
• D. More sensitive to wind than GMAW

Answer: (A)

Higher deposition rate is the main benefit here. Flux-cored arc welding (FCAW) uses a continuously fed tubular wire, and it often runs at higher current with stable spray or globular transfer, allowing long, uninterrupted welds. That means more filler metal is deposited in a given period compared with shielded metal arc welding (SMAW), where you must stop to change coated electrodes and the deposition rate is limited by electrode size and the need to maintain a manageable arc length. The other points don’t capture FCAW’s typical productivity edge: FCAW isn’t limited to ferrous materials, shielding can be provided in a way that isn’t more wind-sensitive than SMAW in all setups, and cleaning requirements aren’t inherently greater. The combination of continuous feeding and higher heat input makes the deposition rate noticeably higher with FCAW.
