By means of laser beam welding it is possible to join plastics parts in micro system technology. Based on existing macroscopic process variants, an appropriate process technology for laser beam welding in order to join plastics micro parts has been developed at IKV. For welding of plastics parts, the influence of material and process parameters on the quality of the weld lines has been investigated. Apart from these studies, a strong effect on the welding process is expected when using different filling materials like, e.g., carbon black. Investigations of microscopic melt zones produced by the focused laser beam are presented.
