  2. Laser beam welding - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_welding

    Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.

  3. Laser welding of polymers - Wikipedia

    en.wikipedia.org/wiki/Laser_welding_of_polymers

    Direct laser welding of polymers. Similar to laser welding of metals, in direct laser welding the surface of the polymer is heated to create a melt zone that joins two components together. This approach can be used to create butt joints and lap joints with complete penetration. Laser wavelengths between 2 and 10.6 μm are used for this process ...

  4. IR welding - Wikipedia

    en.wikipedia.org/wiki/IR_Welding

    IR welding is a welding technique that uses a non-contact heating method to melt and fuse thermoplastic parts together using the energy from infrared radiation. [1] The process was first developed in the late 1900s, but due to the high capital cost of IR equipment the process was not commonly applied in industry until prices dropped in the 1990s.

  5. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

  7. Electron-beam welding - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_welding

    Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
