Sažetak

A comprehensive research of Friction Stir Welding of 4 mm thick sheet aluminium alloy (AlMg4.5Mn) for forming was done. A vast variety of process parameters was tested according to the plan of experiments at constant 2° tilt angle. Specially designed tensile test specimens were sectioned perpendicularly to the welding direction. The microstructure was prepared for the observation on a light microscope under the polarized light source. Vickers micro-hardness was measured. The results show the influence of FSW process parameters on the formation of the microstructure and mechanical properties.
