Weld penetration and phenomena in 10 kW fiber laser welding

ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007
A high-power fiber laser can produce an ultra-high peak power density of MW/mm2 level corresponding to a focused electron beam, and is promising as one of the desirable heat sources for high-speed and deep-penetration welding. This research was undertaken with the objective of obtaining a fundamental knowledge of 10 kW high-power fiber laser welding on

Laser welding of fiber array units

Applied Optics
We report the results of fabricating fiber array unit (FAU) connectors using a near IR laser welding process, locking fibers in proper position on planar glass substrates and forming strong glass-to-glass bonds, followed by final assembly using lower coefficient of thermal expansion (CTE) epoxies.

Fundamentals of fiber laser remote welding and deep penetration welding

CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009
Remote/scanner welding and deep penetration welding with a fiber laser of high power and high beam quality is receiving a great attention since the laser can achieve high-speed welding and deep penetraion welding for mass production. However, welding phenomena are not fully understood.

New application possibilities for fiber laser welding

ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007
Due 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 hybrid welding of stainless steels

ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008
Laser 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.

Effect of fiber laser welding on solute segregation and proprieties of CoCrCuFeNi high entropy alloy

, 2020
The effect of fiber laser welding on solute segregation and proprieties of CoCrCuFeNi high entropy alloy was investigated. The microstructure and mechanical properties of the parent metal and the fusion zone were comparably studied.

Fiber laser – Compact source for micro-welding

ICALEO '98: Proceedings of the Laser Materials Processing Conference, 1998
Fiber 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.

Fiber Laser Welding of Noncombustible Magnesium Alloy

Materials Science Forum, 2008
Noncombustible 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.

Laser transmission welding of long glass fiber reinforced thermoplastics

SPIE Proceedings, 2015
Joining fiber reinforced polymers is an important topic for lightweight construction. Since classical laser transmission welding techniques for polymers have been studied and established in industry for many years joint-strengths within the range of the base material can be achieved.
