Abstract in different language:	Low pressure turbine blades are the most erosion-exposed moving parts of the steam turbine. This article brings a detailed overview of an innovative system applying a stellite coating to the leading edge of the steam turbine blades using the robotic laser cladding technology. The system is based on a software that gathers measured data of the shape-specific workpiece from a laser profile scanner, creates a 3D model of the workpiece and generates a set of laser cladding trajectories that are used for the task of robot navigation during the laser cladding process. The navigation algorithm takes the workpiece-specific requirements of the laser cladding process as well as collision avoidance necessities into account. The shape and thickness of the resulting layer of the laser cladded coating alloy is verified by an external 3D scanning system showing the compliance of the system with the requirements as well as a space for future development. The feasibility of the developed method is also verified by multiple material and metallographic tests.
