Patent number: 10583631Abstract: A method for joining materials using additive friction stir techniques is provided. The method joins a material to a substrate, especially where the material to be joined and the substrate are dissimilar metals. One such method comprises (a) providing a substrate with one or more grooves; (b) rotating and translating an additive friction-stir tool relative to the substrate; (c) feeding a filler material through the additive friction-stir tool; and (d) depositing the filler material into the one or more grooves of the substrate. Translation and rotation of the tool causes heating and plastic deformation of the filler material, which flows into the grooves of the substrate resulting in an interlocking bond between the substrate and filler material. In embodiments, the depositing of the filler material causes deformation of the grooves in the substrate and an interlocking configuration between the grooves of the substrate and the filler material results.Type: GrantFiled: November 10, 2016Date of Patent: March 10, 2020Assignee: MELD Manufacturing CorporationInventors: Kumar Kandasamy, Jeffrey Patrick Schultz

Patent number: 10500674Abstract: An additive friction stir fabrication method and system is described which may be used to fabricate and join a rib to a metallic substrate or to repair a defect in a metallic substrate through extrusion. The method may be carried out with or without the addition of preformed ribs. One such method involves feeding a friction-stir tool with a consumable filler material such that interaction of the friction-stir tool with the substrate generates plastic deformation at an interface between the friction-stir tool and a metallic substrate to bond the plasticized filler and substrate together and extrude this material through a forming cavity to form a rib joined to the metallic substrate. Further described is a system for fabricating a rib joined to a metallic substrate through extrusion.Type: GrantFiled: December 1, 2017Date of Patent: December 10, 2019Assignee: MELD Manufacturing CorporationInventors: Kumar Kandasamy, Jeffrey Patrick Schultz
