superalloy substrate, such as a turbine blade or vane, one on a substrate or more layers or it is processed by laser beam welding to clad or is repaired. The light energy of the laser is transferred to the weld filler material and the underlying substrate, to ensure wetting of the molten and sufficient substrate surface of the filler for good fusion. Energy transfer is maintained at less than the level of exposing the base material to the risk of thermal degradation. Transfer of light energy into the filler and the substrate, since the laser beam and the substrate relatively move relative to one another along a translational path, the change in topology of varying energy transfer amount local base It is uniformly maintained by compensating for.
