Fiber laser hybrid welding of stainless steels
ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008Laser welding gives better penetration than conventional welding methods and can significantly increase the welding speed. Use of laser hybrid welding can further enhance the welding speed by improving gap bridgeability and allowing the addition of filler metal to facilitate welding of special grades.

New application possibilities for fiber laser welding
ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007Due to their unique design, fiber lasers offer new possibilities in the field of laser welding. Especially their higher focusability is known to allow narrow and deep welds which help to increase weld performance and reduce heat input. But, as such beam sources are not yet common in industrial environments, their possibilities and main application ...

Fiber Laser Welding of Noncombustible Magnesium Alloy
Materials Science Forum, 2008Noncombustible magnesium alloy AMC602 (Mg-6mass%Al-2mass%Ca) extruded sheet of 2.0mm thickness was successfully welded using a fiber laser welding process at welding speed of 10m/min at 3kW laser power. Tensile strength of the welded joint was about 82 to 88% of that of the base metal.

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.

Prediction of weld bead for fiber laser keyhole welding based on FEA
ICALEO 2015: 34th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2015Fiber laser keyhole welding as a popular metal joining process has been widely used in a variety of applications especially automotive, shipbuilding and aerospace industries. Although process parameters determination based on experiments is the frequently used in the practical welding, it is often a very costly and time consuming. Accurately predicting
