In the context of WPQ, what does 'acceptance criteria' refer to?

• A. The welder's years of experience.
• B. Customer sensitivity to noise.
• C. Welding consumable supply levels.
• D. The defined criteria that welds must meet to be considered acceptable by the code or standard.

Answer: (D)

Acceptance criteria in WPQ define the standards a weld must meet to be considered acceptable under the applicable code or standard. These criteria set the required tests, allowable defect sizes and types, and the dimensional tolerances that determine whether a weld passes or fails. They come from the governing code or standard and are tailored to the specific joint, material, process, and service conditions, ensuring the weld quality aligns with the intended application. So, the best answer is that acceptance criteria are the defined criteria that welds must meet to be considered acceptable by the code or standard. The other options don’t fit because they relate to factors like a welder’s experience, noise concerns, or supply levels, none of which establish the required quality thresholds for a weld as defined by the code.
