摘要：

The results are presented of an acoustic emission monitoring performed during hydrotests of a thin wall steel pressure vessel. The location of acoustic source was based on longitudinal wave front detection. The careful calibration of the three sensor instrumentation system used for acoustic source location was found to be very useful, and allowed an accurate location error analysis. Acoustic emission in the hydrotests was found to be mainly due to stress release in weld seams.
