What should a source inspector verify regarding the Welding Procedure Specification (WPS)?

A source inspector must verify that the Welding Procedure Specification (WPS) meets the welding configuration or joint design noted on the WPS/PQR (Procedure Qualification Record). This is essential because the WPS provides the critical guidelines for how the welding should be performed, including the type of joint, materials being welded, position, and preheat requirements. Ensuring that the welding procedure aligns with the specified configuration is crucial for achieving the desired strength, integrity, and performance of the weld.

Welding procedures are developed and tested under specific conditions, and deviations from these conditions can lead to potential failures or defects. Therefore, confirming that the welding configuration adheres to the specified criteria within the WPS and PQR is a primary responsibility of the source inspector.

While verifying the updated version of the WPS, the list of qualified welders, and the cost of welding are important aspects, they do not directly pertain to the immediate integrity and applicability of the welding process being inspected. The alignment of the WPS with the specific welding configuration is fundamental to ensuring compliance with industry standards and the overall success of the welding operation.
