LASER MICROCLADDING USING POWDERED FLUX AND METAL

摘要

According to the present invention, powder flux material (93b) for using the laser cladding process, micro- It is provided. Alloy powder material (93a) and a jet of propellant gas containing a powder flux material 92 is directed toward the substrate 94. Powder material is melted to form the weld pool is separated into a layer of the slag-covered (100) by a layer of cladding alloy material (102) (98) a laser beam (96). This flux material is by reducing the weld pool during the cooling of the cladding layer protects the alloy material, thereby to be selected as the propellant gas instead of nitrogen or air to the inert gas. In one embodiment, the base material and the alloy material is a super alloy having a composition of more than a conventional welding area. ;
