  2. Laser beam welding - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_welding

    A derivative of LBW, laser-hybrid welding, combines the laser of LBW with an arc welding method such as gas metal arc welding (GMAW). This combination allows for greater positioning flexibility, since GMAW supplies molten metal to fill the joint, and due to the use of a laser, increases the welding speed over what is normally possible with GMAW.

  3. Heat-affected zone - Wikipedia

    en.wikipedia.org/wiki/Heat-affected_zone

    In fusion welding, the heat-affected zone (HAZ) is the area of base material, either a metal or a thermoplastic, which is not melted but has had its microstructure and properties altered by welding or heat intensive cutting operations. The heat from the welding process and subsequent re-cooling causes this change from the weld interface to the ...

  4. 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 ...

  5. List of welding processes - Wikipedia

    en.wikipedia.org/wiki/List_of_welding_processes

    This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

  6. Laser guided and stabilized arc welding - Wikipedia

    en.wikipedia.org/wiki/Laser_guided_and...

    Laser guided and stabilized welding (LGS-welding) is a process in which a laser beam irradiates an electrical heated plasma arc to set a path of increased conductivity. Therefore, the arc's energy can be spatial directed and the plasma burns more stable.

  7. M squared - Wikipedia

    en.wikipedia.org/wiki/M_squared

    In laser science, the parameter M 2, also known as the beam propagation ratio or beam quality factor is a measure of laser beam quality. It represents the degree of variation of a beam from an ideal Gaussian beam. [1] It is calculated from the ratio of the beam parameter product (BPP) of the beam to that of a Gaussian beam with the same wavelength.

  8. Laser-hybrid welding - Wikipedia

    en.wikipedia.org/wiki/Laser-hybrid_welding

    Laser-hybrid welding is a type of welding process that combines the principles of laser beam welding and arc welding. [ 1 ] The combination of laser light and an electrical arc into an amalgamated welding process has existed since the 1970s, but has only recently been used in industrial applications.
