Abstract

Friction stir welding technique has been used to join AA2024 and AA6061 dissimilar 6 mm thick plate. FSW gives a new trend in dissimilar metal joining process. In addition to joining of aluminium alloys, FSW is used for joining of other materials like steels, polymer etc. Tool rotational speed, welding speed and tilt angle of a tool at three different levels were considered as process parameters. Here, the Fractional factorial design was used to find out the optimum process parameter. With analysis and experimentation, it has been observed that there has been the main effect of tool rotational speed, welding speed and tilt angle on strength of the joint for Aluminium AA2024 and AA6061. In this research paper, percentage contributions from each parameter were computed through which optimal parameters were identified for Aluminum AA2024 and AA6061 plates. Optimum values of tool rotation speed, welding speed, and tilt angle were found out in order to obtain the perfect increased strength of weld joint.
