Friction Stir Welding (FSW) and Friction Stir Spot Welding (FSSW) are new techniques of welding. Since the process of friction stir welding (FSW) differs from friction stir spot welding (FSSW), the appearance and characteristics of the microstructure would be probably different. Therefore, the differences need to be characterized and documented. The main objective of the project is to characterize the microstructure of friction stir spot welding (FSSW) aluminum alloy and friction spot welding (FSW) aluminum alloy using Optical Microscopy (OM), Scanning Electron Microscopy (SEM) and Field Emission Scanning Electron Microscopy (FESEM). This work focused on the weldment area of the welded plates. Both FSW and FSSW sampleswere prepared using the optimum parameters prior to undergoing metallography process. Both thefriction stir welding (FSW) and friction stir spot welding (FSSW) are found to produce microstructural variations across the weld, due to the thermomechanical treatment involved in the process.Eventually, both samples are undergone Energy Dispersive X-ray Spectroscopy (EDS) to identify elemental composition of both sample.
