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. Plastic joining - Wikipedia

   en.wikipedia.org/wiki/Plastic_joining

   Plastic joining is the method of joining semi-finished products of plastic materials together or to other materials as a fabrication process or damage repair. Joining methods can be classified into three categories: Mechanical fastening, Adhesive bonding, Welding.

4. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9]

5. 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.

6. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The efficiency is dependent on the welding process used, with shielded metal arc welding having a value of 0.75, gas metal arc welding and submerged arc welding, 0.9, and gas tungsten arc welding, 0.8. [56] Methods of alleviating the stresses and brittleness created in the HAZ include stress relieving and tempering. [57]

7. Solvent bonding - Wikipedia

   en.wikipedia.org/wiki/Solvent_bonding

   Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...
