What is the purpose of a fillet weld patch?

• A. To reinforce structural integrity of the vessel
• B. To provide a temporary sealing of leaks
• C. To cover permanent welds under special conditions
• D. To serve as a permanent fix for corroded areas

Answer: (B)

The purpose of a fillet weld patch is effectively addressed by stating that it provides a temporary sealing of leaks. Fillet weld patches are often employed when a pressure vessel is experiencing minor leaks that need to be addressed quickly. By covering the leak with a fillet weld patch, a pressure vessel inspector can ensure that the vessel remains operational until a more permanent repair can be conducted. This approach helps to minimize downtime and maintain the safety and functionality of the vessel in the short term. In contrast, while reinforcing structural integrity is an important consideration in pressure vessel maintenance, that is not the primary intention behind using a fillet weld patch. Similarly, while covering permanent welds may be part of certain repair strategies, fillet weld patches are not specifically designed for that purpose. Finally, although they might serve as a temporary solution for corroded areas, they are not intended as permanent fixes, which typically require more comprehensive repair methods to ensure long-term reliability and compliance with safety standards.
