    Magnesium casting alloys are very appealing materials for automotive applications due to their excellent specific strength (weight reduction), sound damping capability, castability, electromagnetic interference shielding ability and etc. Laser welding is also the desired method of joining these materials, which provides high productivity and structural integrity. However, there is a major chall...

    High reflectivity and high thermal conductivity, high vapour pressure of alloying elements as well as low liquid surface tension and low ionisation potential, make laser welding of aluminium and its alloys a demanding task. Problems that occur during welding are mainly
    process instabilities of the keyhole and the melt pool, increased plasma formation above the...

    The development of high strength steels demands for joining methods for these new materials. As welding may be difficult for some of these new steels due to a detrimental effect of weld metal and HAZ on the mechanical properties of the joint, brazing of these steels could be a better solution. Therefore, in this paper, laser brazing of high-strength steels is regarded. Besides the brazeabil...

    Presented at ICALEO 2007

    Laser net shape manufacturing (LNSM) is a laser cladding based technology which can prototype and repair three-dimensional components with complex geometries. Manufacturing macro-parts with small feature size usually requires a small laser beam and slow deposition rate, which sacrifices the manufacturing speed when one contemplates fabricating entire parts. Depositing materials adaptively according to the geometric...
