Under prequalified joints, which processes are listed as using spray transfer when prequalification applies?

• A. SMAW (spray transfer) and GMAW (spray transfer)
• B. SMAW (spray transfer) and FCAW (spray transfer)
• C. MCAW (spray transfer) and GMAW (spray transfer)
• D. GMAW (spray transfer) and FCAW (spray transfer)

Answer: (B)

Under prequalified joints, the welding methods and transfer modes that are allowed without additional testing are specified for each joint family. Spray transfer is a high-deposition, high-heat mode and, in this prequalified context, is listed for certain processes that can employ it safely and effectively for the joint configurations shown. The pairing given—shielded metal arc welding with spray transfer and flux-cored arc welding with spray transfer—reflects those prequalified allowances, meaning these two processes are recognized in the prequalified data as capable of using spray transfer for the applicable joint details. The other options mix processes or transfer modes not listed together in the prequalified section for spray transfer, which is why they aren’t the correct pairing.
