— This invention provides a method for repairing metal parts by removing and replacing worn, damaged, or defective metal material. It also serves as a method for seamlessly joining metal sheets and other parts while retaining the original temper of
the joined parts. This technology, based on ultrasonic additive manufacturing (UAM), achieves strong joints and repairs by enabling the filling of
a channel that has been cut, formed, or otherwise created in a metal structure or between two metal structures.
The aircraft industry requires robust methods for joining metal sheets, structures, and assemblies together in wings, fuselages, and engines. Fusion-based welding methods cannot always be used because they create heat-affected zones, which reduce the mechanical performance of material around the w…
