Abstract: A component is provided with a relative undersize in an area to be subjected to increased stress, for instance, through temperature. The component is made of a hardenable steel. The undersize is overlaid with a non-hardenable steel thereby to provide the full size. A second layer on top of the first layer can be provided. When the second layer is metallurgically bonded in a manner that generates heat, it does not cause a heat affected zone in the base hardenable steel. Blades for steam turbines benefit from this procedure.

Abstract: A tool for locating a predetermined number of turbine blades in relative operative position with each other includes a base with a space and walls with a space between them. Blades are located sequentially and adjacently. An arc of curvature is representative of the arc of curvature for a rotor for accommodating the blades ordinarily. When the blades are located, the curvature of the top conforms with the curvature of the rotor. The blades can then be adjusted and aligned such that when located in the rotor they will be accurately positioned. With a serrated root, the root is located near the plate and held with steeple screws. With a forked root, there is a post between the fork. A finger root is secured between sidewalls.

Abstract: A tool for locating a predetermined number of turbine blades in relative operative position with each other includes a base with a space and sidewalls with a space between them. Blades are located sequentially and adjacently between the sidewalls so that the blades are accurately and snugly located between the sidewalls. The top of the sidewalls has an arc of curvature representative of the arc of curvature for a rotor for accommodating the blades ordinarily. When the blades are located in the space, the curvature of the top of the sidewalls conforms with the curvature of the rotor. The blades can then be adjusted and aligned such that when located in the rotor they will be accurately positioned.
