    Research output: Book/ReportReport


    The aim of this project "The Assembly of Mass-Produced Components" was to develop the laser welding of plastics by studying the weldability of the materials and the effect of welding parameters. The effect of different material properties like pigments and additives were also studied. The weldability of different plastics was trying to improve by using different laser absorbers and laser transmisssive additives and dyes. These studies were oriented to resolve the problems in mass-production and to carry out the real-time quality monitoring system. Welding of 3D geometries in mass production was also clear up in theory and also with some tests.
