Which items must be addressed on the WPS?

The correct response is focused on the necessary components that must be documented within a Welding Procedure Specification (WPS). The WPS serves as a formal guideline used to ensure that welding is performed consistently and meets specific standards. Key elements that need to be included in the WPS include the welding process to be used, any supporting Procedure Qualification Records (PQRs), and the qualification of the welders involved in the project.

The inclusion of the supporting PQR is crucial because it provides evidence that the welding process and parameters outlined in the WPS have been tested and proven to produce a weld that meets specified performance requirements. Documenting the welding process is essential as well because it dictates how the welding should be carried out. Noting the welder's name can help ensure traceability and confirm that the individual performing the welding is properly qualified to do so.

Other options, while relevant to the overall welding process, do not represent critical elements that must be addressed directly on the WPS itself. For instance, the type of electrode used is important, but it might be part of the details in the PQR rather than a standalone item on the WPS. Similarly, the name of a certification body might be useful but is not necessarily a requirement that must be
