Which statement correctly describes the relationship between WPS and PQR?

• A. WPS lists the steps and procedures; PQR records what actually happened during welding under a WPS.
• B. WPS records what happened during welding; PQR lists steps.
• C. WPS and PQR are not related.
• D. WPS is only for code compliance; PQR is only for safety.

Answer: (A)

In welding, a WPS is a written plan that outlines how to perform the weld—specifying the process, materials, joint, position, and the parameter ranges to be followed. A PQR is the record of a test weld made under that plan, documenting exactly what was done and the test results to prove the procedure can produce an acceptable weld. Because the PQR captures the actual welding conditions and outcomes under the WPS, it provides the evidence that the plan works and can be used to qualify the procedure. Production work then relies on a WPS that has been validated by the PQR. The other statements misstate what each document contains or how they relate: one reverses who records steps versus results, another claims no relation, and the last oversimplifies WPS and PQR as only about code or safety.
