Abstract: A method involves filling a hydrogen-lean molten material in a crucible and closing a lid of the crucible and then feeding a first quantity of a compressed dry gas via the crucible to form a dry gas blanket on a surface of the hydrogen-lean molten material. The method further involves feeding a second quantity of the compressed dry gas to a mold assembly to purge the mold assembly and transferring the hydrogen-lean molten material via an opening of the lid of the crucible to a mold cavity of the mold assembly. The method further involves cooling the hydrogen-lean molten material to form a casting.

Abstract: The present disclosure is directed to a system for performing in-situ laser machining on a component within a gas turbine engine, in which the component includes a substrate defining a surface. The system includes a laser system disposed externally of the gas turbine engine, a focusing optic, and a conduit. The laser system includes a laser unit that produces an output beam. The focusing optic is disposed between the laser unit and the component. The conduit defines a first end external of the engine and a second end that ingresses into the engine through an access port. The conduit includes a plurality of mirrors within the conduit. The plurality of mirrors directs the output beam from the laser system onto the component.
