Which of the following requires QA authorization?

• A. No authorization is needed.
• B. Only repairs require QA authorization.
• C. Both repairs and reworks require QA authorization.
• D. Rework requires QA authorization, but repairs do not.

Answer: (C)

The concept here is that any modification to a weld after it has been approved—whether it’s repairing a defect or reworking a section to meet requirements—must go through QA authorization. This keeps the work under formal control so the proper procedure, qualifications, and documentation are in place before the alteration is performed.

Both repairs and reworks involve changing the original weld to address nonconformances, which can affect the integrity and performance of the fabrication. QA authorization ensures that an approved repair/rework method is used, that the personnel and equipment are suitable, and that the work will be verified by inspection after the action. Without this authorization, there’s a risk that changes aren’t performed correctly or aren’t recorded, compromising quality and safety.

So, repairs require authorization, reworks require authorization, and together they both require QA authorization.
