    Presented at ICALEO 2009

    Joining of dissimilar materials is gaining importance especially in the automotive industry. The latest international initiatives concerning the average fleet CO2-emissions force the manufacturers to reduce the fuel consumption and the exhaust gas. This can mainly be achieved by the weight reduction of the vehicles. New methods for weight optimization are enabled by material selections adap...

    Presented at ICALEO 2009

    In this paper, the influences of the gap size on the fatigue strength of welded titanium alloy overlap-joints are studied. A finite element model (FEM) is established to evaluate the local stress concentration of overlap joint. By employing this FE model, the effects of the gap size on the local stress concentration of overlap joint...

    Presented at ICALEO 2009

    Two different high strength steel grades have been welded by a fibre laser as a fillet corner joint. The purpose of the experiments is to use thinner materials of higher strength as a weight reduction strategy. The sensitivity of the welding process to the beam inclination angle, the beam positioning and the focal plane position were studied. High-speed imaging, process emission monitoring, measurement of the weld surface topography, mechanical testing and FE-analysis have been used to ana...

    Presented at ICALEO 2009

    Compared to laser or arc welding used separately, hybrid laser-MAG arc welding show decisive advantages when higher welding speeds, thicker materials, joint fit-up allowance, better molten pool stability, increase of metallurgical joint quality are required. The understanding of the main relevant involved physical processes are therefore very necessary if one ...
