Joining Aluminium Alloys Dissimilar in Thickness by Friction Stir Welding and Fusion Processes

The industrial application field of the Friction Stir Welding process is growing and the initial high potential of this technique is being confirmed. Research centres worldwide along with some major industrial production companies are making progresses in developing this technique up to a know-how level where the transfer to the industrial environment is technologically reliable and economically successful. The present work starts with a comparison of relevant welding features for industrial application when resulting from the FSW and fusion welding processes typically applied to aluminium alloys. FSW has the potential to improve the construction of tailor blanks. The results of welding plates of AA1050; AA2024-T3 and AA5083-H111 with different thickness is presented in terms of surface finishing, residual deformation, metallurgical analysis and static strength efficiency of the joints performed by FSW, GMAW and GTAW.
