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.
Laser welding equipment – Fiber and Nd:YAG laser welders, pulsed and continuous wave, automated and semi-automated workstations, fiber optic cables, custom tooling, accessories and consumables. Laser cutting and micromachining – Systems with up to 5 axes of coordinated motion, proprietary position-based firing laser control, for stainless ...
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.
Laser soldering is a technique where a 30–50 W laser is used to melt and solder an electrical connection joint. Diode laser systems based on semiconductor junctions are used for this purpose. [21] Suzanne Jenniches patented laser soldering in 1980. [22] Wavelengths are typically 808 nm through 980 nm. The beam is delivered via an optical ...
Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
