Abstract
An air-cooled combustor liner segment, including a plurality of spaced apart radially outwardly extending integral heat exchange protuberances or pins is repaired by providing a replacement edge member for a service damaged edge portion including such pins. The damaged edge portion is removed to provide a segment body with a body repair surface, of a first shape, from which the damaged edge portion was removed. A replacement edge member is provided including a plurality of spaced apart radially outwardly extending integral pins to replace pins in the removed edge portion. The replacement edge member includes a replacement edge member repair surface of a second shape matched with the first shape of the body repair surface. The body repair surface and the replacement edge member repair surface are disposed in juxtaposition at a matched junction therebetween so that their respective radially outer surfaces substantially are coextensive. Then the replacement edge member and the segment body are joined by bonding at the matched junction substantially without change in the cooling air flow control about the protuberances.
