AB  - This study presents the using of chamfer angle could increase torsion and impact strength of the
CDFW joint. 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.
