초록
Friction stir welding (FSW) process is used in this research work to optimize the welding process parameters of welding ofAA1100 aluminium alloy. Taguchi grey relational analysis is used for optimization of the process parameters. The weldingprocess parameters considered in this research work are tool rotational speed, feed and axial load against the responseshardness, tensile strength at room and elevated temperature and % elongation at room and elevated temperature. L27orthogonal array is used to conduct the experiments and the impact of the process parameters on the responses are analyzedand presented. The characterization of the weld is analyzed and it is seen that the fine dimples projects ductile fracture andthe cracks present on flat surface exhibits brittle fracture.
