Torsion and impact strength tests were conducted by using the specimens from round aluminum A6061 CDFW specimens that have chamfer angles of 15°, 30°, 45°, 60, 75° and no chamfer angle in both side of friction contact area. The testing results were discussed using results of macrostructure, microstructure and micro-hardness testing. It was found that chamfer angle influenced torsion and impact strength of the weld joint. Specimens with chamfer angle of 30° had maximum torsion strength due to minimum porosity and maximum area of fully plasticized Zone 1 (Zpl1) at the center of weld joint that had the highest hardness. Maximum impact strength found on the specimens that had chamfer angle of 15° due to minimum porosity and broader area of fully plasticized Zone 2 (Zpl2) that has lower hardness, more coarse grains and higher ductility than that of Zpl1.
