What should be done if a weld defect is beyond acceptance criteria?

• A. Continue Welding While Ignoring The Defect.
• B. Postpone The Decision Until After Project Completion.
• C. Remove The Defective Weld And Replace With A Duplicate Weld.
• D. Mark Nonconforming, Stop Welding, And Initiate Repair Or Rejection Per QA Procedures.

Answer: (D)

When a weld defect exceeds acceptance criteria, it is nonconforming. The immediate step is to stop welding to prevent adding more compromised material. The weld should be marked as nonconforming to ensure it isn’t mistaken for an acceptable weld and to provide a clear record for disposition. Then follow the QA procedures to decide the proper path: whether the defect can be repaired under an approved procedure or must be rejected and the component replaced. If repair is allowed, perform it exactly as the approved method dictates and then re-inspect to verify that the defect is corrected and the weld now meets criteria. If repair isn’t permitted, reject the weld or the component and arrange for replacement per the QA plan. All actions, findings, and decisions must be documented and communicated to the relevant parties. The goal is to ensure that only conforming welds are accepted and in service, while controlling and tracing nonconformities to prevent recurrence. After any repair or replacement, a fresh inspection should confirm that the final weld meets all applicable standards and acceptance criteria.
