Comparatively thick pipes of 6061 aluminum alloy and S25C carbon steel were friction welded under a preferable welding condition and the strength distribution on the weld interface was investigated. The results obtained are as follows; (1) According to a decrease of the thickness ratio 0.30, 0.16, 0.15, 0.14, 0.13 and 0.12, the joint efficiency decreased 73.9%, 68.1%, 63.8%, 55.8%, 39.9% and 21.6%, respectively. (2) Friction welding of thin pipe having less thickness ratio <i>t/D</i><sub>0</sub> than 0.11 was difficult to produce a sound weld (<i>D</i><sub>0</sub>: outer diameter, <i>t</i>: thickness of pipe). (3) The tensile strength of each 11.1% area from inner and outer edges of the weld interface was low, and the joint efficiencies were 30∼50%. (4) The joint efficiency of the joint removed inner and outer areas of the weld interface was about 95%.
