  2. Plastic welding - Wikipedia

    en.wikipedia.org/wiki/Plastic_welding

    With speed welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the rod and the substrate, while at the same time it presses the molten weld rod into position. A bead of softened plastic is laid into the joint, and the parts and weld rod fuse.

  3. Spin welding of polymers - Wikipedia

    Spin welding is a form of friction welding used ... This frictional heat causes the plastic to melt and a bond to be created. ... and begin to spin The speed of the ...

  4. Hot plate welding - Wikipedia

    en.wikipedia.org/wiki/Hot_plate_welding

    With hot wedge welding, the speed of travel is an added parameter as the wedge unit is self-propelled by the rollers. The typical temperature range when welding high-density polyethylene (HDPE) is 220 to 400 °C (428 to 752 °F); the travel speed is typically 0.7 to 4 metres per second (2.3 to 13.1 ft/s). [5]

  5. 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 ...

  6. 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.

  7. Extrusion welding - Wikipedia

    en.wikipedia.org/wiki/Extrusion_Welding

    Extrusion welding is an attractive process for applications that take advantage of its ability to weld thick sections quickly. For some applications, especially where there are large geometry parts where more traditional plastic welding methods (such as hot plate welding) is not possible, extrusion welding is the only feasible and cost effect option.
