摘要： A 3-D adaptive laser powder fusion welding system provides for both modeling/gauging of a workpiece as well as repair, restoration, and/or manufacture thereof. By providing a work platform and apparatus support system, five degrees of control in the form of two linear axes and three rotational axes are provided. The sixth linear axis is controlled via the displacement of a laser powder fusion (LPF) welding head and a laser rangefinding head. The laser rangefinding head system enables the workpiece W to be modeled electronically or otherwise. Additionally, the rangefinding system enables a model part to serve as a template from which repairs or construction are affected. The LPF welding head then affects any repairs or manufacture that are needed on the workpiece W. The LPF welding head is powered by filler material. The entire system is generally controlled by computer which enable the operator to be separated from a generally hot and hostile welding environment.

摘要： The present invention provides an apparatus for repairing turbine blades of a gas turbine engine by a laser welding operation. The method uses a miniaturized laser and related apparatus. The miniaturized laser is fed through a borescope access hole to a desired location such as a high pressure turbine blade. The laser is then powered and manipulated so as to perform the desired welding operation. Filler material may also be provided in situ to accomplish the welding procedure. The method realizes a significant cost savings to the vehicle operator in that repairs can be accomplished without the need to remove the engine or disassemble the engine.

摘要： A one-step rapid manufacturing process is used to create three dimensional prototyping parts. Material such as metal, ceramics and the like powder, and wire, and the like, is delivered to a laser beam-material interaction region where it is melted and deposited on a substrate. The melted and deposited material is placed on a XYZ workstation. Three dimensional parts are created by moving the XYZ workstation relative to the laser beam while simultaneously feeding powdered alloys, first in the XY and then in the Z plane. Beam shaping focusing optics can be used to tailor the intensity distribution of the laser beam to the requirements of the deposition layers, and can be used to create parts with desired mechanical or thermodynamic properties. Additional beam splitting and recombining optics can be used to allow powder to be fed at a perpendicular angle to the substrate.
