This paper describes the effect of single cone geometry of friction area on torsion strength of continuous drive friction weld (CDFW) joint of round bar aluminum alloys A6061. Single cone geometry on friction area was determined with ratio of upper diameter (D1) and lower diameter (D2), D1/D2 of cone. Ratios of D1/D2 used were 0.02, 0.25, 0.65, 0.8 and 1. Friction time was 120 seconds. Torsion strength test, macro and microstructure, micro-hardness test were conducted. The results show that D1/D2 of 0.25 gives maximum torsion strength of CDFW joint. It is thought that it occurs due to the wider area of Zpl zone, smaller grain size and more Mg2Si precipitate in the Zpl and Zpd zone and nil or minimum porosity in the CDFW joint. © 2016 AIP Publishing LLC.
