In this study, the following conclusions were obtained after friction stir welding of Al 6061-T651. 1) The organization of the welding unit is largely divided into four parts, the Stir zone, themal-mechanical affected zone, heat affected zone, it was confirmed that it is clearly separated into the material portion. 2) As a result of observing the hardness test results of the welding unit, the minimum hardness value was about 45Hv, which was significantly lower than the hardness of the base material about 72Hv. 3) The tensile strength of the welding part was about 2/3 compared to the tensile strength of the base material.
