  • Method for repairing a casting
    Patent number: 7047612
    Abstract: This invention relates generally to a method for repairing a casting, and more specifically to a method of repairing a casting by pouring melted filler material into a damaged portion of the original casting. Damaged cast metal components, such as a cylinder head of an internal combustion engine are repaired by preheating the component to a first preheat temperature. The damaged area of the casting is then heated to a higher temperature using a torch and melted filler material is poured into the casting. The torch is used to maintain the temperature of the melted material for thirty seconds to two minutes. The temperature of the filler material is then cooled using compressed air.
