2. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   A plastic welding rod, also known as a thermoplastic welding rod, is a rod with circular or triangular cross-section used to bind two pieces of plastic together. They are available in a wide range of colors to match the base material's color. Spooled plastic welding rod is known as "spline".

3. Hot gas welding - Wikipedia

   en.wikipedia.org/wiki/Hot_gas_welding

   Hot-gas welding is a manual plastic welding process for joining thermoplastic materials. A hot-gas torch is used to direct hot air to both the joint surface and weld rod, heating the materials to their softening temperature. Application of pressure on the heated weld rod to the joint surface bonds the materials together to form a completed weld ...

4. Friction welding - Wikipedia

   en.wikipedia.org/wiki/Friction_welding

   Friction welding is a solid-state welding technique similar to forge welding. Instead of a fusion welding process, Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive applications. The ISO norm of friction welding is EN ISO 15620:2019, [2] which contains information about the basic terms ...

5. Radio-frequency welding - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_welding

   Radio-frequency welding. Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials. [1] The electric field is applied by a pair of electrodes after the parts being joined are clamped ...

6. Vibration welding of thermoplastics - Wikipedia

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

   Vibration welding (also known as linear or friction welding) refers to a process in which two workpieces are brought in contact under pressure, and a reciprocating motion (vibration) is applied along the common interface in order to generate heat. The resulting heat melts the workpieces, and they become welded when the vibration stops and the ...

7. Extrusion welding - Wikipedia

   en.wikipedia.org/wiki/Extrusion_Welding

   Extrusion welding is one of the processes used to weld thermoplastics and composites, developed in the 1960s as an evolution of hot gas welding. It can be a manual or automated process. [1][2] The process uses a welding head that has a nozzle for hot air and an extruder that pushes filler material out.
