Abstract
Friction stir spot welding (FSSW) has been proposed as an effective technology to spot weld the so-called “difficult to be welded†metal alloys. In the paper, a variation of the FSSW process has been considered. The method of flat friction stir spot welding (FFSSW) was used to investigate the tensile behaviour of three thin dissimilar aluminium alloys (Two sheets of AA6082-T6 and one sheet of AA6061-T6). Tool with probe and a probe less tool is used in this two-step process of joining. Experiments were conducted at various tool tilt angles (TTA), tool rotational speeds (TRS), dwell time (DT) and Tool plunge depths (TPD). The quality welds were produced at optimized process parameters (TTA 20, TRS 2125 rpm, DT 15 s and TPD 0.1 mm). Elimination of protuberance and reduction of keyhole in the joint is achieved for improving bonding length. Taguchi analysis was used to optimize the parameters of this investigation for obtaining high tensile strength. Micrographs of joints were examined using optical microscopy and scanning electron microscopy (SEM). The complete bonding with finer grains at stir zone (SZ) improved the strength of FFSSW joint. Energy-dispersive X-ray (EDX) and X-ray diffraction (XRD) analysis of specimen indicates the presence of Mg2Si precipitates in SZ. The fracture behaviour of upper and lower interfaces was examined. X-ray diffraction results in compressed residual stress are also obtained as it helps in obtaining the weld free from cracks. The mechanical properties of three-sheet FFSSW joints were compared with other similar techniques of joining. Better understanding of mechanical properties and weld behaviour of three sheets FFSSW is done with the help of fractography and SEM.
