During welding operations, the inspector should do which of the following?

The correct approach for an inspector during welding operations is to confirm that the welding parameters and techniques align with the established Welding Procedure Specification (WPS) and Welder Performance Qualification (WPQ). Ensuring that these specifications are followed is crucial because the WPS provides a detailed description of the welding process, including materials, techniques, and requirements necessary to achieve quality welds. The WPQ, on the other hand, verifies that the welder has the necessary skills and qualifications to perform the welding task as specified. Adhering to these documents ensures consistency, quality, and safety in the welding process, minimizing the risk of defects or failures in the welds produced.

While the other choices might seem to offer potential benefits or solutions, they do not align with the standards and practices expected in welding inspections. For example, altering welding procedures without proper authority could compromise the integrity of the welds and may violate quality assurance protocols. Ignoring minor discrepancies can lead to cumulative issues that might affect the overall quality and safety of the weld. Providing step-by-step instructions during every aspect of the welding process may be impractical and could undermine the welder's autonomy and expertise, which is why inspectors typically focus on ensuring compliance with established standards rather than directing the ongoing activity
