Zusammenfassung:A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.
