5052 aluminum alloy plate with 5 mm in thickness was friction stir welded using a universal milling machine. Effect of push angle on mechanical properties of FSW joint was investigated. The burr was observed on the retreating side without push angle, but it disappeared with push angle. Both the vertical and feed force in which welding process showed higher value in case of with push angle, but the horizontal force with push angle was smaller than to that of without push angle. The tensile strength of FSW joint with push angle increases with increasing of the push angle. Regardless of the rotational speed and feed, the tensile strength of FSW joint with push angle was obtained about 120% to that of the joint without push angle. The elongation of FSW joint showed a similar tendency of the tensile strength.
