abstract The results of vibration welding of glass fibre reinforced nylon 66 (TECAMID 66 GF30) are presented in this paper. The aim of the investigation was to determine the influence of the welding parameters on the quality of joints, which was conducted on the basis of light and scanning electron microscopic examinations as well as tensile tests. The results showed the influence of the vibration welding process on the way of creating the joint, on the material continuity, the orientation of the glass fibres in the welding area and on the joint strength. The joint is created as a result of joining the matrices of two welded materials. The glass fibres in the welding area are oriented in the direction of the vibrations and into the flash. A high tensile strength of joints is possible to achieve in a wide range of welding parameters.
