Patent ID: 8533948

Claim:
A process for producing a rotor which is made by welding disks together, wherein a device is used to join the disks together axially in sequence along a longitudinal axis and the disks are welded in a two-stage welding process comprising: stacking the disks axially in a vertical direction, carrying out a first welding process in a vertical orientation of the stacked disks, and carrying out a second welding process in a horizontal orientation of the stacked disks, wherein the disks are rough-turned in a horizontal position and are then stacked on top of each other in the vertical direction up to a predetermined size, only the first welding process being carried out while a longitudinal axis of the disks which have been joined together is still in a vertical orientation, and the stacked disks, which are prewelded by the first welding process, are then tilted back into the horizontal position, and then the second welding process is carried out on the stacked disks, the longitudinal axis of which is oriented horizontally.
