The feasibility study to join the laser powder bed fused AlSi10Mg alloy sheets using different friction stir welding parameters was investigated in the present work. Fifteen butt-welded joints using varied parametric combinations were developed based on the design of the experiment's approach. An empirical model between the process parameters and tensile strength was developed and used to understand the mechanical behavior of the welded joints w.r.t. the FSW parameters, followed by the attainment of optimized welding conditions using response surface methodology. The results inferred that the weldability was most significantly influenced by the tool rotational speed, followed by the tool tilt angle and tool traverse speed. The microstructure and mechanical properties of the optimized welded joint were compared with the as-built alloy and the welded joint yielding minimum tensile strength. The electron back scattered diffraction analysis revealed the reduction of average grain size of the stir zone of the joints by 21% for the optimized weld, as compared to the as-built alloy. The welded zones of the joints showed a reduction in hardness by 40-50% and formed the stir zone as the weakest link. The parametric combinations of the optimized weld improved the joint efficiency by ≈ 20% compared to the other weld, followed by an improvement in ductility, which was further characterized using scanning electron microscopy.
