Welding procedure qualification tests are used for what purpose?

• A. to determine welding cost
• B. to prove the properties of the weld
• C. to select filler metal
• D. to train operators

Answer: (B)

Welding procedure qualification tests are used to prove that a welding procedure can reliably produce a weld that meets the required properties under the defined welding conditions. This means checking that the chosen process, materials, joint design, and parameters (like preheat, heat input, interpass temperature, shielding, etc.) truly yield welds that meet the code or project specifications for strength, toughness, and integrity. The results document that the procedure is capable, so production welding can use that procedure with confidence. These tests aren’t meant to determine welding cost, select filler metal for cost or convenience, or train operators. Those goals are addressed in other parts of preparation and quality programs; procedure qualification focuses on verifying that the welding process itself will perform to spec.
