Fillet weld patches must have what minimum radius for corners?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 5 inches

Answer: (A)

Fillet weld patches are commonly used in pressure vessel repair to reinforce or repair areas affected by defects or corrosion. The minimum radius for corners in these patches is significant because it helps ensure the integrity and strength of the weld joint. A 1-inch minimum radius is specified to reduce the stress concentration that could occur at sharp corners, which can lead to premature failure in the weld area. Having a minimum radius allows for better distribution of loads and reduces the risk of cracks forming at the corner transition points. Ensuring this radius is adhered to is essential in maintaining the mechanical properties and overall safety of the pressure vessel in service. A larger radius could further enhance stress distribution, but the established minimum of 1 inch provides a balance between practical fabrication considerations and structural integrity. In this context, other options represent larger radii, which while may provide additional benefits, the question specifically asks for the minimum requirement.
