  2. 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 ]

  3. Rotary friction welding - Wikipedia

    en.wikipedia.org/wiki/Rotary_friction_welding

    Rotary friction welding is widely implemented across the manufacturing sector and has been used for numerous applications, [17] [18] [19] including: Parts in gas turbine such as: turbine shafts, turbine discs, compressor drums, [20]

  4. 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

  5. Weld tests for friction welding - Wikipedia

    en.wikipedia.org/.../Weld_tests_for_friction_welding

    Science try to gets good quality welds. There are many scientific articles describing the weld test, e.g. hardness, [2] [3] [4] tensile tests. [3] The weld structure can be examined by optical microscopy [3] [4] [5] and scanning electron microscopy.

  6. Friction stir welding - Wikipedia

    en.wikipedia.org/wiki/Friction_stir_welding

    Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.

  7. Vibration welding of thermoplastics - Wikipedia

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

    Vibration welding is often used for larger applications where the parts to be joined have relatively flat seams, although the process can accommodate some out of plane curvature. Recently, the automotive industry has made extensive use of the process to produce parts like manifolds and lighting assemblies whose complex geometries prevent single ...

  8. 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.

  9. Spin welding of polymers - Wikipedia

    en.wikipedia.org/wiki/Spin_welding_of_polymers

    The spin welding process can adequately join almost all thermoplastic polymers. Typical with friction welding applications, higher melting temperature materials will require more energy to melt, so they will require more welding time or higher RPMs. [3] Common additives and filler will often alter the weldability of polymers. These additions ...
