What is the maximum length of repair allowed before engineer approval is required?

• A. 20% of the total length of the plate
• B. 10% of the total length
• C. 30% of the total length
• D. 40% of the total length

Answer: (A)

Limiting repair length is about keeping any repair localized so the strength and behavior of the weld remain predominantly as designed. The maximum repair length that can be done without engineer approval is 20% of the plate length. For example, on a plate 500 mm long, up to 100 mm of repair is allowed without needing an engineer’s sign-off. If the repair would exceed that limit, engineer approval is required to confirm the method, ensure it won’t compromise the joint, and determine any additional testing or design considerations. The other percentages would either be unnecessarily restrictive or too permissive and don’t align with this standard practice.
