Innovative Friction Stir Welds of Aluminium Alloys Characterizations

Friction stir welding (FSW) is a fast-evolving joining technology with superior advantage over other welding technologies. The viability of FS welds is dependent upon mechanical properties and production turnovers, which are dependent on welding parameters and tool design. This book does not only contain a comprehensive FSW process-structure-property review, but also original research reporting of the multi-objective characterization of Friction Stir Welded industrial and aeronautical aluminium alloys (AA5083-H111, AA6056-T4, AA6082-T6) using the Standard FSW tools, Scrolled Shoulder Triflat tool, and the Bobbin Tool respectively. This thoroughly done review and research feature the first SEM demonstration of material flow patterns, as well as mechanical behaviour, residual stress analyses, failure mechanisms and damage tolerance. Analyses of microstructures and macrostructures clearly reveal the solutions for improved mechanical integrity.
