  • Patent number: 10272520
    Abstract: A joint-site structure for components to be connected by overlap friction welding. At least one step of at least one component, on which an axially set-back ring-shaped joining surface is situated, is provided with a radial undercut, in such a manner that on the face side, a region of this step that is unchanged in diameter forms a radial support ridge, which is connected with the at least one component by way of a heat throttle that is reduced in cross-section. The length of each step is designed in such a manner that when the face surface of the one component makes contact with the ring-shaped joining surface of the other component, the other face surfaces of these components, which surfaces lie opposite one another in the same radial position, are still exposed until completion of the friction-welding process.

  • Patent number: 10137525
    Abstract: A method and friction welding system for friction welding. Metallic components are positioned such that welding surfaces of the metallic components contact each other. A metallic component in the metallic components has a relief feature adjacent to a welding surface for the metallic component. The welding surfaces are moved relative to each other while the welding surfaces are in contact such that solid-state joining of the metallic components at the welding surfaces occurs to form a structure. The relief feature causes a material from at least one of the metallic components to form with respect to the relief feature in a manner that enables performing an additional solid-state joining operation with the structure at a subsequent welding surface on the structure without removing flash.

  • Patent number: 9878489
    Abstract: Friction-weld assemblies and methods of spin-welding are provided, where the components being joined are polymeric components. Designs provided for the polymeric components enable the use of relatively low speeds and pressures to achieve superior friction weld joints between the components. Further, large surface area polymeric components can be successfully friction welded with such designs. In certain variations, at least one polymeric component has a weld surface with a plurality of surface features that are concave (e.g., grooves) or convex. In other variations, the first component in the weld region has a distinct non-complementary shape from the second component, thus creating a progressive advancing weld line that avoids high temperatures that might incur damage to the polymeric component and weld joint. Such component designs additionally provide for improved flash management at the weld joint.

The connecting portion is adapted not to substantially deform upon insertion of the insert portion, and a ratio of minimum diameter and maximum diameter is between about 65% and 90%.

  • Patent number: 8651361
    Abstract: A method of friction welding a workpiece and a component part is disclosed. The workpiece has a weld surface that is coextensive with at least a portion of a virtual surface, which is symmetric about an axis, and the component part includes a complementary surface that conforms to the weld surface. The method includes angularly oscillating the workpiece about the axis; urging the weld surface and the complementary surface together with a first predetermined force to create a plasticized region between the workpiece and the component part; urging the weld surface and the complementary surface together with a second predetermined force; discontinuing angularly oscillating the workpiece; urging the weld surface and the complementary surface together with a third predetermined force; and discontinuing to urge the weld surface and the complementary surface together when the workpiece and the component part coalesce.

  • Publication number: 20140027498
    Abstract: A friction stir processing tool is formed from a Ni-based dual multi-phase intermetallic compound alloy containing rhenium(Re). The Ni-based dual multi-phase intermetallic compound alloy is preferably formed by casting, while gradually cooling, a melt containing all the components of the composition and is preferably heat treated after casting. Moreover, in a method for friction stir processing, a work is softened by friction heat generated when the friction stir processing tool, while rotating, is pressed against the work to be processed. The friction stir processing tool includes the Ni-based dual multi-phase intermetallic compound alloy, and therefore further high hardness is exhibited to improve abrasion resistance, so that even a long period of friction stir processing can be endured.

  • Patent number: 8486508
    Abstract: The invention relates to a method for producing a friction-welded connection between a plurality of superimposed flat components held together by a connecting member, wherein a collar of said connecting member rests on an upper component and the front end of said connecting member forms a friction-welding zone with a lower component, said friction-welding zone being produced by rotation and pressure of the connecting member. After formation of the friction-welding zone, the rotation of the connecting member ceases at the end of a first step and, in a second step, upon cessation of the rotation of the connecting member prior to contact of the collar with the upper component, a pressure is exerted on the connecting member by a pressure-applying tool, said pressure pressing the collar against the upper component because of a deformation.

    Abstract: A method of forming a metallic container includes the steps of providing body and lid portions, placing the body and lid portions together, keeping portions of the body and lid portions in contact with one another, and reciprocally rotating the lid portion with respect to the body portion, thereby generating frictional heat and forming a friction weld therebetween. An apparatus for attaching the lid and body portions of a metallic container includes a base to support the body, a support assembly to support a flange of the body, and a sonitrode for contacting a flange of the lid, wherein the flanges of the lid and body are held together between the support assembly and the sonitrode. A motor reciprocally rotates the sonitrode relative to the support assembly, thereby moving the flanges relative one another to generate frictional heat and create a friction weld therebetween.

    Abstract: A frictional welding process for joining a titanium aluminide turbine to a titanium alloy shaft is disclosed. The disclosed process includes preheating the turbine to a designated temperature, providing a specially-designed joining interface geometry at the distal end of the shaft and optimizing the frictional welding parameters. The frictional welding is carried out in multiple steps but, while the shaft is being spun by a rotating chuck, two different pressures and two different time periods are used until the narrower portions of the distal end of the shaft have been fused onto the welding surface of the turbine. Then, an additional forging step with yet another engagement pressure between the shaft and the turbine is carried out without rotation of the shaft.

  • Publication number: 20120255990
    Abstract: A welding method that utilizes a friction stir welding (FSW) technique to weld large structures, for example, very large cylindrical tower sections of wind turbines. The method involves welding at least two workpieces together by metallurgically joining faying surfaces of the workpieces. The workpieces are placed together so that their faying surfaces face each other and a joint region is defined by and between the faying surfaces. The workpieces are then friction stir welded together by forcing a tool into the joint region, rotating the tool about an axis thereof to cause the tool to penetrate the joint region, and causing the tool to travel along the joint region to form a weld joint that metallurgically joins the faying surfaces and produces a welded assembly comprising the workpieces.
