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.
