The paper presents welding conditions and the process of creating a FSW weld during welding elements made of wrought aluminium alloys and cast aluminium alloy. Investigations were conducted at Institute of Welding, Gliwice (Instytut Spawalnictwa), on the FSW stands equipped with vertical milling machine adapted for friction stir welding process. Influence of the tool’s dimension and shapes on the plasticization process of welded material and formation of a weld behind the tool, at different welding set of parameters were studied. During the investigations it was noticed, that forces and torque occuring during FSW and stiffness of the clamping system influence the temperature of the welding area, the plasticity of the material, the particles fragmentation and the quality of the joints. On the basis of research correct welding conditions were selected and process of welding was conduct using specially designed instrumentation. The views of exemplary friction stir welded elements and macrosections from the welding areas are shown. 14 Ref., 4 Tables, 16 Figures.
Keywords: Friction stir welding, wrought and cast aluminium alloys, copper tool dimension
