Abstract: A method of repairing defects in a casting formed from non-weldable or difficult-to-weld alloys is disclosed. The method includes removing the defect from the casting thereby forming a cavity in the casting, placing a filler material in the cavity and fusion welding the filler material in the cavity. The fusion welding produces surface cracks on the casting and sub-surface cracks in the casting. The method then includes brazing at least some of the surface cracks on the casting and processing the casting with a hot isostatic pressure (HIP) process to close at least some of the sub-surface cracks in the casting.

Abstract: An airfoil includes an airfoil body (110), a cover (120), and a stud (130). The cover (120) is disposed on at least one of a suction side (102) and a pressure side (101) of the airfoil body (110) and the stud (130) extends through the cover (120) and into the airfoil body (110) and the stud (130) is joined to the airfoil body (110) and the cover (120) by a friction weld. A method of manufacturing such an airfoil is also defined.

Abstract: A method is provided for manufacturing at least a portion (24) of a heat exchanger. During this method, a first heat exchanger section (46) is formed that includes a base (28) and a plurality of protrusions (34A,35A,36A). The forming of the first heat exchanger section (46) includes building up at least one protrusion material on the base (28) to form the protrusions (34A,35A,36A). The first heat exchanger section (46) is attached to a second heat exchanger section (52). A plurality of flow channels (38) are defined between the first heat exchanger section (46) and the second heat exchanger section (52).
