In this study, aluminium AA6063 plate of 6mm thickness plate were welded by friction stir butt joint using different tool probe of Square and pentagon with constant parameter of rotational speed transverse speed and axial force of 1500 rpm, 35 mm/min and 5kN.The effect of welding parameter was evaluated in different mechanical properties of hardness distribution and tensile properties for axial weld zone. The significant optimal transverse feed is achieved with high weld quality and excellent joint properties when compared to square tool. In this square tool gives the excellent result was obtained both tensile strength as well as hardness in order to improve productivity. © (2015) Trans Tech Publications, Switzerland.
