Abstract : Friction Stir Welding a variant of Friction Welding has parameters namely tool material, tool geometry, tool pin profile, tool tilt angle, axial force, tool rotational speed and tool transverse speed. Here in the present investigation the effect of pentagon tool pin profile is been studied on joining of dissimilar aluminum alloys AA6061 and AA7075. Tool transverse feed is kept as 31.5 mm/min; tool rotational speed is kept as 765 rpm and tool tilt angle as 2 degrees forward. Mechanical properties, Microstructure, Macrostructure and Temperature profile analysis is been done. Microstructure analysis has been done with the help of Keller's Reagent. Temperature measurement is carried out by K-type thermocouple, embedded at different depths (1.5mm, 3mm and 4.5mm) and at different positions along the longitudinal axis. Aluminum alloy AA6061 is kept on advancing side and AA7075 is on retreating side. Index Terms - Friction Stir welding (FSW), pentagon tool pin profile, AA6061, AA7075
