A method of reworking a component, comprising: at least partially filling a cavity (C) in a non-fusion weldable base alloy (BC) with a filler alloy (F), wherein the filler alloy (F) is different than the non-fusion weldable base alloy (BC); characterised in that : the step of at least partially filling a cavity (C) is carried out such that the cavity (C) is at least partially filled with a multiple of layers of a multiple of laser powder deposition spots formed of the filler alloy (F), wherein each of the multiple of laser powder deposition spots (S) at least partially overlaps at least one of another of the multiple of laser powder deposition spots (S), wherein the method comprises: applying the non-fusion weldable base alloy of the workpiece as a cap (B) at least partially within the cavity (C) and over the filler alloy (F); and electro-spark depositing the non-fusion weldable base alloy cap (B), and applying a coating (T) over the non-fusion weldable base alloy (BC), wherein the filler alloy (F) is PWA 795 and the non-fusion weldable base alloy (BC) is MAR-M 247. at least partially filling a cavity (C) in a non-fusion weldable base alloy (BC) with a filler alloy (F), wherein the filler alloy (F) is different than the non-fusion weldable base alloy (BC); characterised in that : the step of at least partially filling a cavity (C) is carried out such that the cavity (C) is at least partially filled with a multiple of layers of a multiple of laser powder deposition spots formed of the filler alloy (F), wherein each of the multiple of laser powder deposition spots (S) at least partially overlaps at least one of another of the multiple of laser powder deposition spots (S), wherein the method comprises: applying the non-fusion weldable base alloy of the workpiece as a cap (B) at least partially within the cavity (C) and over the filler alloy (F); and electro-spark depositing the non-fusion weldable base alloy cap (B), and applying a coating (T) over the non-fusion weldable base alloy (BC), wherein the filler alloy (F) is PWA 795 and the non-fusion weldable base alloy (BC) is MAR-M 247. the step of at least partially filling a cavity (C) is carried out such that the cavity (C) is at least partially filled with a multiple of layers of a multiple of laser powder deposition spots formed of the filler alloy (F), wherein each of the multiple of laser powder deposition spots (S) at least partially overlaps at least one of another of the multiple of laser powder deposition spots (S), wherein the method comprises: applying the non-fusion weldable base alloy of the workpiece as a cap (B) at least partially within the cavity (C) and over the filler alloy (F); and electro-spark depositing the non-fusion weldable base alloy cap (B), and applying a coating (T) over the non-fusion weldable base alloy (BC), wherein the filler alloy (F) is PWA 795 and the non-fusion weldable base alloy (BC) is MAR-M 247. applying the non-fusion weldable base alloy of the workpiece as a cap (B) at least partially within the cavity (C) and over the filler alloy (F); and electro-spark depositing the non-fusion weldable base alloy cap (B), and applying a coating (T) over the non-fusion weldable base alloy (BC), wherein the filler alloy (F) is PWA 795 and the non-fusion weldable base alloy (BC) is MAR-M 247. <EOS>
