Continuous Drive Friction Welding (CDFW) is a process of connecting metal solid cylinders without melting which is carried out in a solid state below the melting point. In the CDFW method heat is generated by friction on the object to be connected. During the connecting process there are several important parameters that affect to the strength of the connection. One parameter that greatly affects the weld quality is the time friction parameter. This study aims to determine the effects of friction time variation on temperature distribution, microstructure and hardness of solid metal joint Stainless Steel 304 with Aluminum 6061 T6. In this study the materials used are stainless steel 304 and aluminum 6061 T6 cylinders. The friction time variation in this parameters are 2 second, 4 second and 6 second. While the other parameters are constant at 25 Mpa pressure, 50 Mpa upset pressure, 2 seconds upset time and 1000 Rpm engine speed. This test was conducted to determine the effect of friction time variation on temperature distribution, micro structure and vickers hardness using the ASTM E 384 standard. The results of the distribution of temperature seen from the graph can be explained that the longer the friction time given, the heat generated from this friction welding method is higher. The microstructure testing of this study on 2, 4 and 6 seconds of friction time explained in 6061 T6 aluminum joints experienced the most obvious changes where Mg2Si sticks together and converges very tightly. The best level of hardness is in the variation of friction time 6 seconds and then 4 seconds and the lowest is 2 seconds and it can be concluded that the longer the friction time given, the better the hardness value produced.
