摘　　要：某厂生产的热水器内胆,在进行水压疲劳试验时,多次发生直焊缝开裂漏水事件。通过对热水器内胆裂纹的检测与分析,结果表明,焊缝与基体夹角处存在较大应力集中是导致断裂产生的主要原因。In the Water pressure fatigue test of the water heater tank produced by a factory, the cracking and leakage of straight weld occurred many times. Through the idetection and analysis of the cracks in the tank of the water heater, the results show that the stress concentration at the angle between the weld seam and the matrix is the main cause of the fracture.

关 键 词：热水器内胆 裂纹 应力集中
