การเชื่อมด้วยการเสียดทานแบบกวนรอยต่ออลูมิเนียม 6063 และเหล็กกล้าไร้สนิม 304

Abstract

his paper presents the experimental results of the Friction Stir Welding (FSW) of AA6063 aluminum alloy and AISI304 stainless steel butt joint by varying the welding parameters such as the rotating speed and the welding speed. The main results are as follows; The variation of welding parameters produced various characteristic interfaces and had conspicuous influences on the joint properties. Increasing the rotating speed and the welding speed decreased the joint tensile strength because it produced the defect on the joint interface. The optimum welding parameter that could produce the sound joint was a rotating speed of 750 rpm and the welding speed of 102 mm/min with the tensile strength of 71 MPa.
