Abstract
Friction stir welding is an innovative welding process for similar and dissimilar joining of the materials effectively. FSW simply modified the grain structure and also improved the strength of the joints for any type of alloying elements. This experimental study planned to carry out the joining process for dissimilar materials such as aluminium alloys 5083 and 7068. Three different types of tools are involved to find the ultimate tensile strength and Vickers hardness. The tool types are straight cylindrical tool, taper cylindrical tool, and triangular tool. The process factors for this investigation are a rotational speed of 800, 1000, 1200, and 1400 rpm, welding speed of 30, 40, 50, and 60 mm/min, axial force of 3, 4, 5, and 6 kN, and plate thickness of 5, 6, 7, and 8 mm. The hardness value and the ultimate tensile strength were increased in the welding zone, which proves the effects of tool profiles are efficiently utilized.

Summary
The aluminium alloy is one of the effective materials used worldwide in all field applications, and due to the excellent strength of the aluminium alloy, it is used for all structural work in the construction field [1]. The friction stir welding method is used to weld a minimum-thickness plate without damaging the specimen, and the FSW process eliminates the bending of the work part after welding [2,3,4]. The tool rotational speed and welding speed are directly influenced in the welding strength of the components, and it reflects on the mechanical test. All sheets and plates are welded effectively; nowadays, the circular specimen is welded through the FSW process in the pipe joint and solid round bar joint successfully [6]. The lot of researchers used the FSW process effectively, and this investigation planned to conduct the dissimilar weld joint using the material of AA5083 and AA7068 successfully. The different parameters influenced are rotational speed, welding speed, axial force, and plate thickness [10]
