2. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to ...

3. Plastic weld non-destructive examination - Wikipedia

   en.wikipedia.org/wiki/Plastic_weld_non...

   Various forms of ultrasonic inspection are used for plastic welds. Plastics have higher attenuation and a lower sound velocity compared to metals which can make these techniques more challenging. [2] In 2010, a joint European project, TestPEP, was started to develop and validate ultrasonic NDE techniques on plastic welded pipe. [5]

4. Radio-frequency welding - Wikipedia

   en.wikipedia.org/wiki/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 together.

5. Poly(p-phenylene oxide) - Wikipedia

   en.wikipedia.org/wiki/Poly(p-phenylene_oxide)

   This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260–300 °C. The surface can be printed, hot-stamped, painted or metallized. Welds are possible by means of heating element, friction or ultrasonic welding. It can be glued with halogenated solvents or various adhesives.

6. Ultrasonic welding of thermoplastics - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_welding_of...

   The materials to be welded experience similar vibrations to those in plunge welding but shorter in time. [3] Hold force to the newly welded region is provided by previously welded section that has come out of the tooling and cooled down. [1] Scan welding is a type of continuous ultrasonic welding in which case large plates or sheets can be ...

7. Implant induction welding of thermoplastics - Wikipedia

   en.wikipedia.org/wiki/Implant_Induction_Welding...

   Implant induction welding is a joining method used in plastic manufacturing. The welding process uses an induction coil to excite and heat electromagnetically susceptible material at the joint interface and melt the thermoplastic. The susceptible material can be contained in a gasket placed between the welding surface, or within the actual ...
