Abstract : This paper reported the effect of upset pressure and holding time on porosity and tensile strength of aluminum alloys A6061 continuous drive friction welded (CDFW) joint. Friction weld specimens were welded using upset pressure variations of 40, 80 and 120 MPa. Variations of upset holding time were 3, 10 and 20 seconds. Porosity test was performed using Pycnometric method. Tensile strength test was conducted according to AWS standard. It was found that higher upset pressure and longer holding time in upset stage can reduced porosity of CDFW weld joint. This state also gives result of higher tensile strength of specimen with higher upset pressure and longer holding time. Fracture surface observation also shows that fracture surface of the specimen with higher upset pressure and longer holding time is more brittle than that of specimen with lower tensile strength as result of lower upset pressure and shorter holding time. Index terms - Continuous Drive Friction Welding, Upset Pressure, Holding Time, Porosity, Tensile Strength.
