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. 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 ]

4. 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".

5. 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 ...
