Fiber laser – Compact source for micro-welding
ICALEO '98: Proceedings of the Laser Materials Processing Conference, 1998Fiber lasers combine the advantages of solid-state lasers and diode lasers, such as high beam quality and high efficiency. Examinations concerning the micro-welding process were carried out with a 9 Watt CW fiber laser. The wavelength of 1100 nanometers is similar to Nd:YAG radiation, which is established in material processing.

Weld depth control in fiber laser welding of thin metal sheets
ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008Laser beam welding of electrical connections or sealing of casings are typical applications in the field of precision engineering. Controlling the shape of the welded connections is an important issue in this context. A common requirement is for example to achieve a specific welding depth in order not to damage functional layers or contaminate the ...

The microstructures, tensile properties, strain hardening, and fatigue strength of fiber-laser-welded (FLW) and diode-laser-welded (DLW) AZ31B-H24 magnesium alloys were studied. Columnar dendrites near the fusion zone (FZ) boundary and equiaxed dendrites at the center of FZ, with divorced eutectic β-Mg17Al12 particles, were observed. The FLW joints had

Hybrid Welding of AA5754-H111 Alloy Using a Fiber Laser
Advanced Materials Research, 2012The new generation of high power fiber lasers presents several benefits for industrial application. Nevertheless, due to the small spot size of the laser, the fiber laser has difficulties in some welding applications. These shortcomings can be overcome by laser-arc hybrid welding technique such as laser-gas metal arc welding or laser-gas tungsten arc ...
