Description
Summary:The recently developed innovative joining process, Friction stir welding (FSW) is connected to make the best quality of strength and hardness of the welded joints. The lightweight nonferrous materials are focused on aircraft hydraulic systems, fuel tank and transportation ventures due to its high strength to weight ratio and corrosion resistance. The joining of aluminum alloys is extremely troublesome in the conventional fusion welding process because of its cementing shrinkage, hot breaking, scatter, fumes and residual stresses. The friction stir processing is connected to enhance the mechanical properties of the friction stir welded joints by the addition of Nanoparticles viz., SiC and AkO3. The investigation was made on the microstructural analysis of the similar and dissimilar friction stir welded and processed AA 8011-H24 and AA 6061-T6 aluminum alloy joints by Scanning Electron Microscope and the presence of alloying elements in the welded region was found by Electron Dispersive Spectroscopy.
