  2. Vibration welding of thermoplastics - Wikipedia

    en.wikipedia.org/wiki/Vibration_Welding_of...

    Most machinery operates at 120 Hz, although equipment is available that runs between 100 and 240 Hz. [1] Vibration can be achieved either through linear vibration welding, which uses a one dimensional back and forth motion, or orbital vibration welding which moves the pieces in small orbits relative to each other. Linear vibration welding is ...

  3. Rotary friction welding - Wikipedia

    en.wikipedia.org/wiki/Rotary_friction_welding

    [4] [6] Europe through KUKA AG and Thompson launched rotary friction welding for industrial applications in 1966, developed a direct-drive process and in 1974 built the rRS6 double spindle machine for heavy truck axles. [7] [8] newIn 1997, an international patent application was filed, entitled "Method of Friction Welding Tubular Members".

  4. Friction stud welding - Wikipedia

    en.wikipedia.org/wiki/Friction_stud_welding

    Friction stud welding is a solid phase welding technique involving a stud or appurtenance being rotated at high speed while being forced against a substrate, generating heat by friction. The metal surfaces reach a temperature at which they flow plastically under pressure, surface impurities are expelled and a forged weld is formed.

  5. Friction welding - Wikipedia

    en.wikipedia.org/wiki/Friction_welding

    Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [ 1 ]

  6. Friction stir spot welding - Wikipedia

    en.wikipedia.org/wiki/Friction_stir_spot_welding

    In friction stir spot welding, individual spot welds are created by pressing a rotating tool with high force onto the top surface of two sheets that overlap each other in the lap joint. The frictional heat and the high pressure plastify the workpiece material, so that the tip of the pin plunges into the joint area between the two sheets and ...

    The dog's a star! Well she's the star of a video her human sister made. Her first film ever in fact. The Bully was incredibly patient as the "director" executed her dream. She saw the vision and ...

  9. List of welding processes - Wikipedia

    en.wikipedia.org/wiki/List_of_welding_processes

    The oldest welding process in the world. Oxides must be removed by flux or flames. Damascus steel: Friction welding: 42: FRW Thin heat affected zone, oxides disrupted by friction, needs sufficient pressure Aerospace industry, railway, land transport Friction stir welding: 43: FSW A rotating non-consumable tool is traversed along the joint line
