The Application of the Bobbin Tool in the Friction Stir Welding of Aluminium Sheets

The article presents the effect of the technological parameters of the friction stir welding of 2 mm thick aluminium sheets made of aluminium alloy EN AW 6082 performed using of the bobbin tool. The tests included static tensile tests, hardness tests and macroscopic metallographic tests. The tests revealed that properly selected welding parameters enabled the obtainment of joints characterised by material continuity, compact structure and the lack of welding imperfections in the welding area. The application of the bobbin tool made it possible to obtain joints of aluminium sheets characterised by high strength, i.e. amounting to 61% of the base material strength.
