Claim Text:
1. A system for cladding a turbine component having a substrate and a surface with a filler layer, comprising: a work table apparatus for receipt of a turbine component substrate thereon, having a work table interface; a laser profilometer apparatus for scanning a surface of the turbine component substrate and acquiring component dimensional data, having: a scanning laser generating a scanning laser beam for reflecting optical energy off the turbine component surface; at least one movable scanning mirror intercepting the scanning laser beam, for orienting the scanning laser beam on the substrate surface; and a laser profilometer apparatus drive system interface coupled to the scanning laser and the at least one movable scanning mirror, for causing relative movement there between; a cladding filler material distribution apparatus for introducing filler material on the component substrate; a laser welding apparatus for transferring optical energy to the turbine component substrate and filler material on the substrate that fuses the filler material to the substrate as a built up filler layer that is applied as a welding pattern, having: a welding laser generating a welding laser beam for transferring optical energy; at least one movable welding mirror intercepting the welding laser beam, for orienting the laser beam on the substrate; and a welding laser apparatus drive system interface coupled to the welding laser and the at least one movable welding mirror for causing relative movement there between; a drive system operatively coupled to the work table, the profilometer, the cladding filler material distribution apparatus, the laser welding apparatus and their respective drive interfaces, for operating the apparatuses and providing controlled relative motion there between; and a control system operatively coupled to each of said apparatuses and their drive interfaces, for: acquiring component dimensional data with the laser profilometer apparatus; comparing the acquired component dimensional data with component specification dimensional data; based on the comparing of component and specification dimensional data: determining respective filler introduction and/or welding patterns for cladding component substrate surface portions to conform welded component dimensions to the specification dimensional data; and causing the filler apparatus and the laser welding apparatus execute their respective patterns in order to clad the component substrate.
