摘要
A method for repairing/manufacturing an integrally bladed rotor for a turbine or turbo engine, in which, in the case of a repair, at least one vane section to be replaced is removed leaving a stub section to which a replacement vane section is to be welded, and, in the case of manufacturing, a carrier to be provided with vanes has stubs projecting over its peripheral surface, to each of which a vane is to be welded, includes the steps of: arranging an inductor around the front face of the stub section or stub; positioning a replacement vane section or vane at a small radial distance from and aligned with the stub section or stub; and welding the replacement vane section or vane to the stub section or stub, respectively, in a protective gas atmosphere by exciting the inductor with high-frequency current and moving the opposing heated part surfaces together.
