Humping in welding with single-mode fiber lasers

ICALEO 2006: 25th International Congress on Laser Materials Processing and Laser Microfabrication, 2006
The availability of lasers with highest beam quality at laser powers of 1 kW or more (such as single-mode fibre laser, which nowadays come close to the theoretical limits) provides a unique tool to investigate a wide range of welding process phenomena with penetrations of some 10 µm to penetrations of some mm.

Analysis on Fiber Laser Welding of MS1470 Steel

Advanced Materials Research, 2011
MS1470 steel is mainly used in the automotive industry, which has high strength, light weight and low cost. However, there always appear grains coarsening, brittle increasing, lower intensity and other issues. To solve this problem, we have analyzed the welding process, the fracture morphology and microstructure etc.

Welding of dissimilar materials with 1kW fiber laser

ICALEO 2010: 29th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2010
Majority of applications in a range of industries i.e. automotive, electronics, medical devices etc requires welding of dissimilar materials. In principle, a laser can weld any material, which can be joined by conventional processes. In the welding of dissimilar metals, good solid solubility is essential for sound weld properties. The trends of welding
