Fillet weld patches may be installed on:

Fillet weld patches may be installed on:

• A. Only on the inside wall of the vessel
• B. Only on the outside wall of the vessel
• C. Either the inside or outside wall of the vessel
• D. Either the inside or outside wall of the vessel if approved by the Owner/User

Answer: (C)

Fillet weld patches can indeed be installed on either the inside or outside wall of a pressure vessel. This versatility allows for greater flexibility during repairs. It is essential to consider factors such as access for welding, the pressure and temperature conditions within the vessel, and the specific type of damage being addressed when deciding where to place a patch. Using fillet welds effectively allows inspectors and maintenance personnel to restore the structural integrity of the vessel, regardless of its surface being inside or outside. This approach is commonly seen in practice since both interior and exterior applications can be designed to meet the necessary codes and standards for pressure vessels. Understanding the context of this question helps highlight that the choice of patch application isn't strictly limited to one wall type but can be determined based on the vessel's condition and operational parameters.
