| Abstract: | In this paper, a specification of multiple stresses accelerated life test for friction welded joints in boiler serpentine pipe was worked out.Based on the specification, high-temperature internal pressure burst duration test was done for a large number fiction welded joints of 15CrMo and 12CrlMoV steel. Through calculation and analysis of the test results,the concordance of the failure mechanism on the different combined stress levels were verified and the reliability mathematical model for friction welded joints was set up. |
