Abstract: This paper highlights the main aspects involved in the process of friction stir welding (FSW) realised by means of a robotic manufacturing workstation, showing the outcomes of theoretical and experimental analyses. The cell is equipped with a hybrid industrial robot, whose static performance is successfully exploited for the realisation of welding products with high mechanical properties. The robot flexibility of use is addressed. Several tests allow to gain a deeper understanding of the effect of technological parameters on FSW processes. Such information can be used for the development of model-based controllers, which are assumed to effectively improve accuracy and process stability also in the welding of complex geometries.
