Abstract: This study reveals the effect of surface roughness and chamfer angle on tensile strength of Continuous Drive Friction Weld (CDFW) joint of round aluminum A6061. CDFW specimens had chamfer angle of 15, 30, 45 degree and no chamfer angle. The both chamfered friction area of the specimens had surface roughness of 0.697, 0.9 and 1.067 μm. From the tensile strength test results, it was found that the lower surface roughness and the smaller chamfer angle will give higher tensile strength. The maximum tensile strength of CDFW joint was found in the specimen with surface roughness of 0.697 μm with chamfer angle of 15°. It may occur due to the minimum porosity, the maximum area of fully plasticized zone 1 (ZPl1) which has high hardness, minimum area of fully plasticized zone 2 (Zpl2) that have lower hardness in the CDFW joint. SEM fracture surfaces showed smaller dimple fracture in the specimen with maximum tensile strength compared to that of specimen with lower tensile strength.
