| Abstract Scope |
Friction stir welding (FSW) is an effective method for repairing cracks in 6061-T6 aluminium alloy, which is sensitive to temperature fluctuations. This study focuses on the repair of a 2 mm square groove using a novel approach that combines an aluminium filler rod with SiC nanoparticles for optimal crack filling. FSW was applied to both cracked and uncracked samples to assess the repair's efficiency. Various evaluations, including tensile strength, microhardness, and microstructural analysis, were conducted to determine repair success and identify defects. Results showed that repaired samples exhibited superior mechanical properties compared to uncracked ones, although some defects were noted during scanning electron microscopy analysis. This research underscores the potential of modified FSW techniques for enhancing crack repair in demanding applications. |
