  Recently friction stir welding for manufacturing of welded tubes has been developed. Friction stir welding is a continuous solid state welding process in which a non-consumable rotating tool using severe plastic deformation Can join materials can be join materials. Commonly, a portion of a specially shaped rotating tool is plunged between metalsjoint cross section and adjacent faces of the joint. After entering the rotating tool on the weld, a relative movement between the rotating tool and the friction heating surface creates a plastic deformation zone around the submerged sections of the tool. The work piece will be heated during the friction stir welding, but the work piece temperature will not reach to the melting point. One of the major problems for manufacturing the thin cylindrical tube is related to low mechanical strength while the melting method such as laser is applied. In this research, it is reveals that the friction stir welding method can be a reasonabletechnique for manufacture of thin cylindrical parts. In this paper, an attempt was made to show thepossibility of frictional stir welding for manufacturing of thin cylindrical AA 6063aluminum parts. Various ranges of welding parameters include of rotation speed and welding speed are implemented to the thin thickness bent sheet i.e. 1.5 mm.By considering on obtained cylindrical tubes, it is found that the sound seem thin tube is achieved in rotational speed of 2500 rpm and welding speed of 4 mm/min respectively. پرونده مقاله
