This to repair a turbine blade, the replacement for the implementation of the process and the blade thus repaired

摘要

The present invention relates to a method for repairing a blade (10) used in a turbine to gas. said blade (10) has a first flat - shape (11), a second flat - shape (13), and an aerodynamic profile (16) extending between the first and second flat - forms (11, 13). The method consists in removing the first flat - shape (11) and the aerodynamic profile (16) of the blade (10) in their entirety, and to remove a part of the second flat - shape (13) allowing a portion of the blade is machined (15), to provide a replacement element (40) having at least a first flat - the form of a replacement (43) and an aerodynamic profile of the replacement (42) and to connect the portion of the blade is machined (15) and the replacement element (40).
