description: Aluminum alloys of the 7th series are used in the aerospace and transport industries, as well as for the manufacture of military equipment and nuclear energy equipment. A major problem with this alloy is that it is difficult to join it by conventional fusion welding techniques. Since this welding method leads to decrease strength and ductility in the heat-affected zone in alloys of the 7th series, and this, in turn, leads to brittle fracture, hot cracks, porosity, and defects. In several studies it could be found that better compounds can be achieved when FSW is adopted. Using a solid state joining process the occurrence of defects that result from fusion welding could be prevented. Three types of FSW were realised in the work: standard FSW, impulse FSW and high-speed FSW for the purpose of research the influence of the parameter and geometry of the tool on the quality of the friction stir welded B95 aluminium plates. The research performed metallographical studies, tensile tests, and the microhardness of the welds was measured. On the basis of the work accomplished a need optimize tool geometry and welding parameters, in order to achieve a higher quality and improved mechanical properties of the weld seam of aluminum B95 alloy.
