Abstract: A method for repairing a cast component having a damaged area is provided. The method includes scanning an area adjacent to the damaged area to create a scan. The method includes forming a dam with a void. The void has a profile corresponding to the scan. The method includes positioning the dam adjacent to the damaged area. The method includes heating the cast component. The method includes introducing a repair material into the dam. The method also includes cooling the cast component. The method further includes removing an excess material from the cast component.

Abstract: A repaired piston includes a crown composed of base and welding filler materials, and having an annular rim extending around a combustion bowl. A finite number of repaired defects are within the annular rim, and have a spatial distribution limited by a multidirectional spacing parameter, and a size distribution limited by a unidirectional sizing parameter.
