Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Influence of configuration of tool shoulder and pin working surfaces on weld formation quality was studied, and design of the tool for friction stir welding of sheet (0.8-3.0 mm) aluminium alloys was developed. Influence of the main welding process parameters, namely angle of tool inclination relative to the vertical axis and force of tool pressing to the surface of the edges being welded, speed of tool rotation and linear displacement, depth of its shoulder immersion into the metal being welded and depth of tool pin penetration into the butt, on weld formation quality was analyzed. Optimum parameters of FSW process were established, which allow producing sound welds on nanostructured quasicrystalline aluminium alloys of Al-Fe-Cr system. Optimum ranges of welding speed variation were determined, at which maximum temperature of metal heating in the zone of permanent joint formation does into exceed 450 C that provides sound formation, dispersed and dense structure of welds and allows preserving the quasicrystalline shape of metastable particles in alloys of Al-Fe-Cr system. Mechanical properties and structural features of typical joints of nanostructured quasicrystalline aluminium alloys obtained by stir friction welding were determined.
