Aluminium alloys are of much use in several vital areas including aerospace, marine, defence and railways, which becomes obligatory to have a welded joint of high strength. The input considerations of the friction stir welding process of double-sided type play an imperative part in identifying the performance and characteristics of the joints. This research is a novel approach to investigate the influence of weld input parameters on the output responses of aluminium 6082-T6 alloy using tapered square and tapered pentagonal tool pin profiles. The double-sided friction stir welding (FSW) was chosen for the research work, as it gives better strength joint than single-sided ones. Response surface methodology (RSM) was used to establish the interactions through mathematical relationships, considering the FSW process parameters and output responses. The influence of tapered square (TSP) and tapered pentagonal pin (TPP) profiles on the welding characteristics was analysed. Also, an extended investigation was carried out in achieving the welding parameters in optimum level, so as to maximize the output responses.
