Which of the following is NOT a requirement when performing weld build-up in a corroded area?

• A. Electrode strength should equal or exceed the base metal strength
• B. The surface irregularities should be ground smooth
• C. This activity must be authorized by the Inspector
• D. Total repair depth is limited to 50% of the nominal plated thickness

Answer: (D)

The correct choice emphasizes an important aspect of weld build-up in a corroded area. Specifically, the statement regarding total repair depth being limited to 50% of the nominal plate thickness is not a requirement during the process of weld build-up. In many cases, the extent of repair can be more than 50% based on the specific conditions, the code in use, and the established guidelines that govern the repair procedures. When addressing weld build-up, ensuring that the electrode strength meets or exceeds the base metal strength is critical for maintaining the integrity and durability of the weld. A weaker weld could lead to premature failure under stress or operational conditions. Additionally, it is essential to grind surface irregularities smooth to promote a proper bond and encourage effective fusion between the new weld material and the existing structure, thereby ensuring a good repair. Moreover, any significant alterations or repairs, including weld build-up, must indeed be authorized by the Inspector to ensure compliance with safety standards and regulatory mandates. This oversight helps to ensure that the repair meets the expected engineering criteria and does not compromise the vessel's operational integrity. The absence of a strict enforcement on the total repair depth as given in the incorrect option reflects a recognition that the specific context will dictate the appropriate limits for repairs
