Abstract: A method is provided for reconditioning a blade of a gas turbine. The blade includes a blade airfoil, with a pressure side and a suction side, which extends in the blade longitudinal direction between a platform and a blade tip, and has a leading edge and a trailing edge, and is outwardly delimited by a pressure-side wall and a suction-side wall which converge at the trailing edge of the blade airfoil, forming discharge openings for cooling air which are arranged in a distributed manner along the trailing edge between the walls.

Abstract: A method is provided for reconditioning a turbomachine vane cover plate, by a forming apparatus. The vane having a mounting portion, an airfoil extending radially outward therefrom and a vane head connected to the airfoil. The vane also having a cover plate connected to the vane head, bulged in a direction opposite to the root. In a first analysis step, dimensions of the vane in relation to the cover plate are determined in respect of predefined reference points. If, thereafter, forming of the cover plate seems necessary and possible based on comparison of measurement values from the analysis step with predefined dimension values, the bulged cover plate is formed, at least essentially pressed smooth, by pressing by the forming apparatus in a forming step. After the forming step, the cover plate is re-treated in one or more follow-up steps. An apparatus is also provided for carrying out the method.
