摘　　要：制造了炉胆与管板连接为角焊缝结构的锅炉,对锅炉角焊缝区域进行了实际工况应力测试与温度测试。制造了角焊缝区域尺寸为1:1的近实际结构实验模型,对模型进行了局部应力场相似的液压低周疲劳试验,循环次数高达24万次,从而证明了角焊缝结构可以在锅炉结构设计中应用。After building a boiler with fillet weld connecting furnace tube and tubeplate, the practical stress and temperature measurements have been carryed out near the weld on the boiler. Mean while, a testing model with the same fillet weld in size as practical one has been built. On the testing model, existing similar stress field, on experiment of low cycle fatigue up to 240.000 was done. From this, we can evertually deduce this kind of constructure of fillet weld on boiler is successful in application.
