Friction Stir Welding is a newer replacement of conventional fusion welding for joining low melting point materials. The solid-state nature of this unique process makes it almost defect –free welding process for critical joints. The FSW set up for the experimentation was completed by developing necessary tool and fixture and joints were made on Universal Milling machine. The present research work investigates the effect of some desired input parameters for Friction Stir Welding on the electrical conductivity of AA1350 aluminium butt joints. Rotational speed of tool, Tool Traverse speed (welding speed), and tool tilt angle were opted as input parameters. Objective of the whole experimentation is to find the best combination of input parameters for maximum conductivity at nugget area of FSW joint. After experimentation with selected parameters, investigation by ANN is done. Back propagation (BP) algorithm is utilised for developing the network. After ANN modelling, optimization of FSW parameters by full factorial method is also investigated. The ANN result outcome and the experiment data was found to be in good agreement. The optimum value of electrical conductivity of welded joints obtained was 52.7 IACS.
