Samples were performed using CNC milling machine. Range of tool eccentricity was 0-0.3 mm, rotational speed and feed rate were variable. The influence of applied welding parameters on microstructure and mechanical properties of joints was assessed on the basis of metallographic inspections and tensile tests. Microstructural observations have shown that the change of FSW tool eccentricity affects the weld geometry: the mixing zone depth, the weld width, or the shape of the contact line.
