    Abstract: Resistance heating, preferably with applied pressure, is used to consolidate incremental volumes of material to produce a desired object in accordance with a description thereof. The joining of the material increments may occur in the solid state, liquid state, or ‘mushy’ state in conjunction an atomically clean faying surface between the increments without melting the material in bulk. Residual stresses are minimized, particularly in metal objects, by imposing a compressive residual stress on the surface of each deposited layer or increment, which offsets all or a portion of the tensile stress created as the next layer deposited above it cools. In terms of apparatus, a moving cathode is used to ensure uniform electrical current flow in an object with constantly changing geometry. The contact resistance of the interface between the workpieces is preferably continuously measured, and the sensor data is used to update a look-up table, or as input to an adaptive closed loop control system to ensure consistent welding conditions as object geometry changes continually. Also disclosed are embodiments associated with the fabrication of functionally gradient materials.

    Abstract: A continuous, single-step, low-temperature process combines metal coating with the splicing of fibers, producing a single, continuous low-cost process for embedding fibers in metal, and/or the splicing of fibers with a joint featuring uniform composition and high strength requiring no additional adhesives. The method can be used to create terminations for cables, or it can be used as a method of splicing or joining optical fibers by positioning the ends of the two fibers under the foils, so that they abut prior to creating the bond. The consolidation material may be provided in sheets, with or without fiber-locating grooves or, alternatively, droplets may be used. In the preferred embodiment, ultrasonic vibrations are used as the source of consolidation energy. A range of metals are suited to the process, including aluminum, copper, titanium, nickel, iron and their alloys as well a numerous other metals of more limited structural utility.
