Method of manufacturing a turbine rotor

摘要

A method for joining a cast metal material blade ring (10) and a metal material hub (30) structure into a turbine rotor (50). One of the blade ring and the hub structure is mounted in a holder and the other is mounted in a rotation holder (120) for being rotated. At least one of these mountings is heated, and then they are pressed together with a selected force while rotating to weld the ring interior wall and the disk side to form the assembled structure.
