LASER POWDER DEPOSITION WELD REWORK FOR GAS TURBINE ENGINE NON-FUSION WELDABLE NICKEL CASTINGS

The present application relates to a cast component for a gas turbine engine, which includes a cast component non-fusion weldable base alloy with a cavity filled with a multiple of layers of laser powder deposition spots of a filler alloy (F). The filler alloy (F) may be different than the non-fusio...

Zusammenfassung:	The present application relates to a cast component for a gas turbine engine, which includes a cast component non-fusion weldable base alloy with a cavity filled with a multiple of layers of laser powder deposition spots of a filler alloy (F). The filler alloy (F) may be different than the non-fusion weldable base alloy. A layer (T) of non-fusion weldable base alloy is at least partially within the cavity and over the filler alloy (F).
