New Approach for Assembling Dissimilar Materials: Laser Technology

The research of new assembly technologies for dissimilar materials is growing up continuously mainly for avoiding the adding of chemical adhesive, assembly elements or additional materials, and gives the possibility to join complex geometries structures while maintaining their integrity. The present study proposes a new approach for developing high resistance hybrid joining between metal and polymer. This complete non-contact laser process allows to strongly join up to the breaking of the polymer part without affecting the joining area. The research has been focused on substrates having complex properties such as high reflectivity, thin thickness or transparent. Different laser sources with various pulse durations have been studied in order to evaluate their efficiency for a hybrid joining.
