Abstract
A method for welding metal composite materials, including metal-ceramic composites, whereby a weld or filler material is prepared by the in-situ precipitation of ceramic in a metallic matrix. The filler material may comprise boride, carbide, oxide, nitride, silicide, etc., while the matrix metal may constitute a alloy or intermetallic of two or more metals. A strong bond is achieved when welding two conventional metals, a conventional metal and a metal-ceramic composite, or two metal-ceramic composites.
