Abstract (en)
[origin: WO2004051056A1] The invention relates to a turbine shaft (2, 8) for a steam turbine, oriented in an axial direction (19) and comprising a first (5, 13) and a second flow region (6, 14). According to the invention, a first material is provided in the first flow region (5, 13) of the turbine shaft (2, 8), and a second flow region is provided in the second flow region (6, 14) thereof, the first material having heat-resistant properties and the second material having cold-resistant properties. The inventive turbine shaft (2, 8) is produced by means of a construction weld seam (4) without any previous buffer layer welding on one of the two materials.
