Effect of FSW Process Parameters on Dry Sliding Wear Behavior of Friction Stir Welded Dissimilar Aluminum Alloy AA6061 T6 and AA5083 O

摘要

Joining of dissimilar aluminum alloy using fusion welding has been a challenging task.Friction stir welding (FSW) is arelatively new solid state welding which overcomes all the setbacks of fusion welding.An attempt has been done to FSW dissimilar aluminum alloys and analyse the effect of the process parameters such as tool pin profile, tool rotational speed, traverse speed and axial force on the wear rate and wear resistance of the joints. A central composite design with four factors and five levels were run to reduce experiments.
