  • Method for repairing a receiving hook for guide vanes
    Patent number: 9931719
    Abstract: Disclosed is a method for repairing a receiving hook for guide vanes, wherein the receiving hook is arranged in a housing of a turbomachine. The method comprises removing first material in a region of the receiving hook, which region extends over the circumference of the housing and thereafter applying second material in or on a region which extends over the circumference of the housing. The application of second material is performed using localized heat.

  • Method of Producing a Welded Joint
    Publication number: 20090184153
    Abstract: A method of producing a welded joint between components of a turbomachine is described, in particular for the repair of components, wherein components are welded to one another along common edges in such a way that a pocket-like recess is incorporated in a first component, in particular in a replacement part, with which recess the first component is slipped onto a second component, in particular a component to be repaired, such that the second component bears with an end edge on a base of the pocket-like recess, and that the first component and the second component are then welded to one another. According to the invention, at least one cutout is incorporated in the first component in addition to the pocket-like recess in order to minimize heat transfer and the formation of component deformations during the subsequent welding of the components.
