An experimental technique based on stacked structures was developed to observe the material flow behavior ofthe friction stir welding (FSW)process.Analysis ofsection views along different directions revealed important new details ofthe material flow in FSW process.In this work,a general flow model ofFSW was constructed based on the analysis ofdifferent static section views ofstacked structure weld.The formation ofonion rings was found to be a geometric effect due to layered deposition and the extrusion occurred at the interface between flow arm (FA)and stirring zone (SZ).
