Abstract
A system and method for repairing defects such as bumper holes, cracks, freckles and inclusions, in a cast article, such as a turbine component. The system comprises a device for locating a defect in a cast article, a repair material that is disposable at a defect site, at least one heat source capable of heating the repair material and a portion of the cast article to a molten state. The method of using the system comprises locating a defect in the cast article, providing a repair material to the defect site, melting the repair material and cast article at the defect site, and cooling the molten repair material and portion of the casting article such that they resolidify and fuse together. The method may further comprise removing a portion of the cast article at the defect site, removal of excess repair material and inspecting the cast article following repair of the defect.
