【 摘 要 】

Present work investigates the effect of tool pin design and process parameters in Friction stir welded 6061 Al alloy. The three pin designs selected were the square, circular and triangular type. It was seen that the triangular pin tool was generating a defective joint area containing flash and pores. SEM and microhardness analysis showed that square tip tool produced a good quality weld with high strength and elasticity comparing with circular and triangular pin tools. High tool rotation and low travel speed were generating a uniform weldment. Finally, tensile testing results showed a maximum value of 107.2 MPa ultimate tensile strength.
