Friction stir welding (FSW) has a wide scope. Friction stir welding (FSW) process is a solid state joining process in which the material that is being welded does not melt and recast. An investigation has been carried out on the friction stir welding of Al Alloy (AA6061) grade aluminum alloy plates. Four different tool pin profiles (Square, Straight cylindrical, Threaded and Triangular) be used to fabricate joints in a single and sequential double sided. In this investigation, tool rotation and traverse speeds be kept constant i.e. 3080 rpm and 30mm/min. The joints fabricated by single pass have shown lower tensile strength and also percentage of elongation compared to the joints fabricated by double pass and this trend is common for all the tool profiles. The results of our work were shown by histogram graph.
