An experimental analysis and optimization of process parameter on friction stir welding of AA 6061-T6 aluminum alloy using RSM

Friction stir welding (FSW) process is an emerging solid state joining method in which the material that is being welded does not melt and recast. The welding parameters such as tool rotational speed, welding speed and axial force plays a major role inn deciding the joint characteristics. In has investigation central composite design technique and mathematical model was developed by response surface methodology with three parameters, three levels and 20 runs, was used to develop the relationship between the FSW parameters (rotational speed, traverse speed, axial force,) and the responses (tensile strength, Yield strength (YS) and %Elongation (%E) were established.
