摘　　要：采用超声波水浸探伤方法对7A04铝合金榴弹壳体进行无损检测,通过试验找出最佳探伤参数。实弹演习证明该检测方法可行而且可靠。为榴弹壳体内部质量控制提供了科学依据。The method of the ultrasonic flaw detection in water was used to do the non-destruction inspection with the high explosive shell. The optimum parameters have been acquired through the test. The result of the inspection has been proven by the practical exercise of the real shell. The feasibility and reliability of the inspection method have been proven, too. So it has provided the scientific foundation to control the internal quality of the shell.
