A method of reworking an aerospace component includes removing a casting defect from a component manufactured of a non-fusion weldable base alloy to form a cavity. The cavity is then at least partially filled with a multiple of layers of discrete laser powder deposition spots of a filler alloy. A cast component for a gas turbine engine 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. The filler alloy may be different than the non-fusion weldable base alloy. A layer of non-fusion weldable base alloy is at least partially within the cavity and over the filler alloy.

A splicing apparatus for joining a trailing end of a downstream metal strip to the leading end of an upstream metal strip includes a base having a working surface, a cover assembly operatively connected to the base and movable between an open position and a closed position, a fixed platen fixedly secured to the working surface, a moving platen slidably connected to the working surface, and a laser device for both cutting said downstream and upstream metal strips and for welding said metal strips together, the laser device including a laser source and a laser head in communication with the laser source, the laser head being connected to said cover assembly.
