<p>The method involves securing multiple moving blades (15) at a rotor base body (10) by a welding process i.e. electron-beam welding process, the blades at grooves (11) formed in the rotor base body, where the grooves extend radially outside in an axial direction (13) of the rotor base body. The blades are inserted into the grooves with blade roots (17) or adaptor (18), such that the central axis of the grooves is inclined opposite to the central axis of the blade roots or the adaptor, so that a pretwist is formed at the moving blades with the insertion of the moving blades into the grooves.</p> |
