초록	The engine exhaustive valve became essential as the important element. The dissimilar welding method of exhaustive valve head to stem was asked for manufacturing the engine exhaustive valve, for which the electric resistance are welding has been conventionally used, resulting in poor quality of the welded joint. In this paper, not only the development of optimizing of friction welding with more reliability and more applicability but also the development of in-process real-time weld quality(such as strength and toughness) evaluation technique by acoustic emission for friction welding of the engine exhaustive valve(SUH3-SUH35 dissimilar steels) were performed. The high temperature(500, 550, 600°C) creep properties prediction of the friction welded joint of SUH3-SUH35 was investigated relating to the initial strain method(ISM) as a new approach, resulting in obtaining an experimental equation of creep life prediction.
