A termination tab member formed of a 1000 series, 3000 series, 6000 series or 8000 series aluminum alloy is disposed in abutting contact with end faces of joining portions of first and second members (in an abutting part), on the side of termination of the welding operation, and the friction stir welding operation is terminated after a probe of a rotary tool is moved from the joining portions of the two members into the termination tab member.

  • Patent number: 9862054
    Abstract: Additive friction stir methods for repairing substrates, coating substrates, fabricating/adding/attaching ribs, joining substrates, stiffening and enhancing structures, surface modification, enhancing surface properties, welding, coating, and extrusion are described. An additive friction stir fabrication method and system is described which may be used to fabricate and join a rib to a substrate or to repair a defect in a 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 substrate to bond the plasticized filler and substrate together and extrude this material through a forming cavity to form a rib joined to the substrate. Further described is a system for fabricating a rib joined to a substrate through extrusion.

  • Patent number: 9849541
    Abstract: Provided is a method and tool for butt welding a first material piece of metal to a second material piece of metal at opposed longitudinal edges. The second material piece has a greater material thickness than the first material piece. The first material piece has a higher tensile strength and/or a higher inching temperature and/or a higher yield strength and/or a higher modulus of elasticity than the second material piece. A thickened longitudinal edge is provided at the first material piece. The thickening of the longitudinal edge is at least partly produced by at least simple folding, beading or winding of the first material piece or at least partly by folding the first material piece at its edge. The two material pieces are friction-stir welded at their front along the opposed longitudinal edges.

  • Patent number: 9815152
    Abstract: A method for repairing a defect affecting a weld. A sheet of filler metal is placed on the surface of the welded part, next to the region of the defect. The sheet is locally welded to the welded part in the region of the defect using a friction stir welding tool having a retractable welding pin. The welded part and the sheet are separated such that the filler metal amalgamated with the metal of the welded part remains in position. The local welding operation includes successively performing the following: setting the welding tool into rotation and putting it under pressure; inserting the pin to a small distance from the anvil while maintaining or increasing the pressure on the shoulder of the welding tool; progressively retracting the pin while maintaining or increasing the pressure on the shoulder; and stopping the pressure on the shoulder when the retractable pin has been retracted.

  • Patent number: 9652812
    Abstract: A plurality of software instances deployed in a monitored environment are discovered by a software asset management tool operated by a software asset administrator who is responsible for monitoring software license compliance within the monitored environment. The software asset management tool then collects metrics associated with the plurality of software instances. The collected metrics are then provided to a first analytic service adapted to generate analytic information about the plurality of software instances. Using at least the collected metrics, the analytic service generates analytic information. The analytic information is then obtained from the analytic service. By reviewing the analytic information, the software asset administrator is able to obtain additional insight into the monitored environment that would not otherwise be available to him.
