Which statement best describes who must approve all proposed methods of welding procedures and testing?

• A. They must be approved by either the inspector or the piping engineer.
• B. They can be approved by the plant safety officer.
• C. They can be approved solely by the owner.
• D. They require no formal approval.

Answer: (A)

Welding procedures and their testing must undergo formal review and approval by qualified technical authorities responsible for the piping system. In practice, this approval should come from someone with engineering or inspection authority over the project—the inspector or the piping engineer. This ensures the procedures meet applicable codes and the specific design and service requirements, and that there is accountability and traceability for how welds are performed and tested. A plant safety officer typically does not authorize technical welding methods, and while the owner oversees the project, they do not independently approve the technical details. Formal approval is required because these procedures directly impact weld quality, reliability, and safety, and cannot be left unapproved or informal.
