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

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

Wobbling Technique in Remote Fiber Laser Welding
2011Remote Fiber Laser Welding is becoming a common solution in many manufacturing applications, such as in Automotive and Energy Industries. However, the high beam quality of such lasers leads to narrow weld beads. Therefore, a wobbling optical equipment and technique is proposed to enlarge the weld bead in Remote Fiber Laser welding while preserving the ...
