Process for energy beam solid-state metallurgical bonding of wires having two or more flat surfaces
First Claim
1. A process and apparatus for energy beam assisted solid-state metallurgical bonding of a wire, having two or more flat surfaces, to a substrate, for the purpose of substrate coating, 3-Dimensional component buildup, restoration and component surface improvement, and comprising the steps of:
- applying of a continuously fed wire to a substrate such that the bottom of the wire flat surfaces are tangential to the substrate such that the contact of the wire with the substrate constitute substantially a surface;
an energy beam is simultaneously applied to the wire, with a magnitude controlled to be sufficient to produce a sudden compressive shock wave and heat at the surface of the wire to propagate through the wire and the top surface of the substrate;
whilst some material particles of the wire are carried with the shock wave and are penetrating into the substrate, producing a strong metallurgical bond without substantial liquefaction of the substrate.

Abstract
An energy beam assisted solid-state welding welds a wire material to a substrate. A wire of coating or repairing material is placed in contact with a surface or surfaces of a substrate. A beam is directed into an outer flat surface of the wire, which heats the wire through flat outer surface of the wire with beam energy. Beam energy produces compression stress-waves that drive molecules of the material flat wire into a surface of the substrate, joining the material and the substrate with strong wave shaped interfaces.
