Friction welded butt joints have come into wider use because of their easiness to fabricate composed shafts such as steering shaft, rear axle shaft and so forth. However, the welding condition optimum to obtain high joint efficiency in terms of fatigue strength has not yet been established because of a scarcity of fatigue strength data. Accordingly, it is indispensable to accumulate fatigue strength data on a variety of joints fabricated under different friction welding conditions. In this study, the rotating bending fatigue behavior of butt joints of aluminum alloy A6061 and austenitic stainless steel SUS304 which were friction welded at three different upset pressures are discussed. The results indicate that the butt joints friction welded at the highest upset pressure give almost the same fatigue strength as that of the aluminum alloy specimen. But the distribution of the fatigue lives of this kind of joint is larger than that of the joint of similar aluminum alloy, presumably depending on the scatter of fatigue crack initiation life.
