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.
