Abstract: A structure and method are provided for preventing or at least minimizing thermally-induced structural distortions, such as may occur when a steam turbine is cooling down. The steam turbine may include an inner housing and an outer housing. An intermediate space is formed between the inner housing and the outer housing, and sealing steam may be injected into the intermediate space to avoid the formation of temperature strata in the interspace and thus prevent the outer housing from bowing.

Abstract: A method for the cohesive connection of two components, in particular two rotating shaft parts, in a connecting region, is provided, wherein integrally formed portions for manipulating the surface geometry of the components are positioned adjacent to the connecting region, wherein the two components are welded together and wherein a subsequent heat treatment is carried out for the targeted introduction of residual compressive stresses, the distribution of which is also determined by the manipulated surface geometry.

Abstract: The invention relates to a moving-blade row of a fluid-flow machine, the moving-blade row having individual adjacent moving blades which each have a moving-blade root and a moving-blade center region and also a moving-blade tip and a leading edge and a trailing edge, the moving blades being mechanically connected to one another in the moving-blade center region by supporting elements in such a way that undesirable vibrations of the moving blades are effectively avoided.
