When a fault is discovered after welding is completed, what is the first recommended action?

• A. Immediately isolate the area
• B. Document, evaluate, perform NCR, and schedule rework or replacement
• C. Notify customer and halt production temporarily
• D. Proceed with repairs without containment

Answer: (B)

When a fault is found after welding, the first action is to formally capture and control the defect through the documented nonconformance process. Start by documenting the fault clearly—where it’s located, what type of defect it is, what weld and material are involved, who observed it, and when. Then evaluate the defect to determine its impact on safety and performance, and decide on disposition. A Nonconformance Report is issued to record the deviation, assign responsibility, and track the corrective action. Finally, plan and schedule the approved remedy, such as rework or replacement.

This approach creates a clear traceable record, ensures proper decision-making before any further action, and aligns with quality and welding procedures requirements. It prevents hiding defects or proceeding with repairs without proper containment or authorization.

Isolating the area, notifying the customer and halting production, or repairing without containment may be necessary steps in some situations, but they aren’t the first formal action. Documentation, evaluation, NCR, and planned rework or replacement establish a controlled, traceable path for defect resolution.
