A method for automated super alloy laser cladding which has three-dimensional imaging welding path control

Japanese Patent JP6100379

B2

Superalloy components, such as service-degraded turbine blades and vanes, are clad by laser beam welding. The welding/cladding path, including cladding application profile, is determined by prior, preferably real time, non-contact 3D dimensional scanning of the component and comparison of the acquired dimensional scan data with specification dimensional data for the component. A welding path for cladding the scanned component to conform its dimensions to the specification dimensional data is determined. The laser welding apparatus, preferably in cooperation with a cladding filler material distribution apparatus, executes the welding path to apply the desired cladding profile. In some embodiments a post-weld non-contact 3D dimensional scan of the welded component is performed and the post-weld scan dimensional data are compared with the specification dimensional data. Preferably the welding path and/or cladding profile application are modified in a feedback loop with the pre- and/or post-welding 3D dimensional scanning.
