  2. Spacers and standoffs - Wikipedia

    en.wikipedia.org/wiki/Spacers_and_standoffs

    Two sizes of metal standoffs and one plastic standoff. The background depicts a standoff in use, holding a circuit board above a metal case. A standoff is a threaded separator of defined length used to raise one part in an assembly above another. They are usually round or hex (for wrench tightening), often made of stainless steel, aluminum ...

  3. Spin welding of polymers - Wikipedia

    en.wikipedia.org/wiki/Spin_welding_of_polymers

    Spin welding creates a clean and sound weld joint that requires little post processing. [3] Due to this most parts being welded are in the final stages of production, or are in final assembly. The first known application of spin welding was in the assembly of compasses, however spin welding has become used in a wide variety of products.

  4. 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".

  5. Plastic weld non-destructive examination - Wikipedia

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

    Radiography uses an X-ray tube or radioactive source to give an image of the weld. Its use is similar to metal welds and provides a volumetric inspection which can show defects in the weld not visible from the surface. For plastics, a lower radiation intensity is typically required than that for metal welds, due to the lower material density. [1]

  6. 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 ...

  7. Weld nut - Wikipedia

    en.wikipedia.org/wiki/Weld_nut

    Round base nuts. These nuts have a long threaded cylinder with a large circular base to make welding easy. They also sometimes have projections (known as weld nibs or bosses) to keep the nut from warping while welding with a high current. [1] Slab base nuts. These are very similar to the round base nuts, but with an obround, or slab shaped ...

  8. Welding of advanced thermoplastic composites - Wikipedia

    en.wikipedia.org/wiki/Welding_of_Advanced...

    When the welding direction is parallel to the orientation of the fibers, the weld width is usually narrower due to heat being channeled through the fibers to the front and the rear of the weld. [ 6 ] Increased volume fraction of reinforcements such as glass can scatter the laser beam, thus allowing less to be transmitted to the weld joint.
