Abstract

The paper is focused on the research in welding of plastic materials PP, PA 6.6 a ABS. This study deals with the optimization of individual parameters of the transmission laser welding process. The welds’ quality evaluation was based on the testing of thermal and mechanical properties. The plastic materials were modified using the colouring pigments, nucleation agents and glass fibres.
