Which welding processes are deemed prequalified as long as they conform to clause 10?

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

Answer: (A)

Prequalified welding processes are allowed without separate procedure qualification as long as you stay within the limits defined in clause 10. That clause specifies which processes qualify for prequalification and also which transfer modes are acceptable under those prequalified conditions. In this standard, SMAW, SAW, FCAW, and GMAW are recognized as prequalified processes, and the spray-transfer versions of MCAW and GMAW are included too. So, using any of these processes with the spray-transfer option, while complying with clause 10 (materials, thickness, weld position, filler metal type, shielding gas, etc.), lets you rely on prequalified procedures. If you go outside those limits, you’d need to qualify a welding procedure.
