According to AWS D1.1, which welding process is prequalified?

• A. SMAW
• B. GMAW
• C. GTAW
• D. SAW

Answer: (D)

Prequalified welding processes in AWS D1.1 are those you can use with a standard welding procedure without performing a separate procedure qualification, as long as you stay within the limits the code sets for material, thickness, joint type, and position. Submerged Arc Welding is included in that list, which is why it’s recognized as prequalified. This means you can apply a WPS for SAW and rely on the code’s prequalification provisions for typical structural steel applications without having to qualify a new procedure, provided the work stays within the specified material and thickness ranges. (Other processes like SMAW, GMAW, and GTAW are also common welding methods that may be prequalified under different conditions, but the item in question highlights SAW as a prequalified option.)
