Abstract
The exhaust systems are usually subjected to vibration or shock at high temperatures. The high temperature fatigue tests of the exhaust systems are rarely performed in domestic industries due to limited number of test facility and high test costs. In this paper, the high temperature fatigue test of some part of the exhaust system, not the whole system, is carried out. The resonator located at the central range is heated in the cylindrical electric furnace and the alternating load is applied on the end of the pipe welded to the resonator. The high temperature fatigue strength of the welded joint is obtained. The location of the fatigue crack is different to that in room temperature.
