摘要： A turbine rotor which is easy to manufacture and has a high tolerable temperature is provided. A highly efficient steam turbine power plant is also provided. The turbine rotor is configured from a rotor shaft, an inner rotor disc constructed integrally with the rotor shaft, and an outer rotor disc which is welded to the inner rotor disc via a weld metal part and has a structure for fixing a turbine blade. The outer rotor disc preferably has a cooling hole which extends in an axial direction to penetrate the outer rotor disc over the thickness of the outer rotor disc.

摘要： Dissimilar metal welds including a buttering portion with a small variation in strength distribution in a plate thickness direction are formed by welding two parent materials having at least one of different compositions and different refining conditions through a buttering for alleviating mismatch between one of the different compositions and the different refining conditions of the two members and through a welded metal for joining one of the parent materials and the buttering. The buttering is formed of welding metals laminated in a plate thickness direction, and a dilution ratio of the buttering with the parent materials is 50% or less. The manufacturing method includes performing butt welding on a dummy material formed by increasing a groove depth by providing a member on a bottom side of a welding groove and on parent materials by using the buttering; and processing a groove within a welding metal formed of the buttering.
