Abstract
A first tubular, inner radial annular seam is produced to weld together two hollow cylinders by narrow-gap tungsten inert gas arc welding. Narrow-gap metal gas-shielded arc welding is used to create another tubular, outer radial annular seam to further weld together both hollow cylinders. In this manner, the rotational axis of the rotor shaft remains vertically aligned throughout the entire production method of welding together the shaft parts. In this manner, the required production time can be advantageously reduced and the use of welding filler can be effectively decreased.
