Abstract (en)
[origin: WO2018078048A1] Method for producing a turbomachine impeller (14), which has a radially inner hub body (14a), a radially outer shroud body (14b) and blades (14c) extending between the hub body (14a) and the shroud body (14b), wherein the blades (14c), the hub body (14a) and the shroud body (14b) are designed as an integral, monolithic assembly, comprising at least the following steps: providing a blank (10); milling the blank (10) to form a basic contour (11a, 11b, 11c) of the hub body, the shroud body and the blades; performing build-up welding or additive manufacturing at least once on the main contour that is formed and subsequently performing milling at least once on portions (15n) that are formed by the build-up welding.
