What should be done with defects outside the permissible limits of the applicable specification?

• A. The decision is up to the welding inspector
• B. Repaired
• C. Always double checked using NDT
• D. Ignored if minor

Answer: (B)

When defects are identified that exceed the permissible limits specified in the relevant standards or specifications, the appropriate course of action is to repair them. This is because the integrity and safety of the welded structure are paramount, and any defect that falls outside of acceptable limits can potentially compromise these factors.

Repairing defects ensures that the welded joint meets the required standards for strength, durability, and performance. It is often a necessary step to maintain the quality and safety of the final product, especially in critical applications such as in construction, aerospace, or pressure vessels. Standards are typically established to provide guidelines that support the overall structural reliability, and addressing defects is vital in upholding these standards.

Other approaches, such as laxly ignoring defects or leaving decisions solely to the discretion of the welding inspector without following proper protocols, could lead to significant safety risks and regulatory non-compliance. Therefore, repairs are essential in maintaining the quality of work in welding and ensuring that the final product meets all required specifications.
