摘要
研究制定了旨在研究电站锅炉蛇形管焊接接头可靠性的加速寿命试验的试验规范 ,在此基础上 ,对大量的15CrMo和 12CrlMoV钢摩擦焊管接头进行了高温内压爆破持久试验。通过对试验结果的分析处理 ,证明了在各种加速试验工况下焊接接头的失效机理是一致的 ,同时也说明了试验规范是可行的。
A test specification for the accelerated-life test of utility boiler coil-tube welded joints was developed for the study of the latter's reliability. On this basis high-temperature internal-pressure explosion endurance tests were conducted with regard to a huge amount of resistance welded 15CrMo and 12Cr1MoV steel tube joints. An analytical processing of the test results has demonstrated the consistency of the failure mechanism of the welded joints under various accelerated-life test conditions, testifying at the same time to the validity of the test specification.
