Both the welding procedure specifications and the cold welding processes specify requirements for non-destructive testing – so which one should be taken as the primary standard and which as a secondary one?

Generally, if there is a conflict between the non-destructive testing requirements specified in the Welding Procedure Specification (WPS) and those in the cold welding process (such as specific procedures or standards), the requirements of the cold welding process shall prevail, as they are standards tailored to the specific processing conditions. The non-destructive testing requirements in welding procedure specifications are primarily based on general standards and guidelines, and may need to be adjusted according to specific process conditions. Specifically, the final implementation standards should be determined based on project requirements, customer requirements, applicable regulations and standards, as well as the agreement between the two parties. In practice, it may be necessary to consult professional quality inspection personnel or project managers for confirmation. If any standard mentions this, it may be necessary to consult the industry standards or specifications from that time to verify it. .

The welding operation instructions and cold welding procedures are presumably established by the company itself; if there are any conflicts, consult the person who developed them. If it’s a test question, pretend I didn’t say anything

Both the welding procedure sheets and cold welding processes are formulated in accordance with the design drawings or relevant standard specifications; in case of any conflicts regarding inspection requirements, the design drawings or relevant standard specifications shall take precedence
