Ultrasonic nondestructive evaluation is a well-established technique for characterizing defects in engineering components and structures. A high frequency pulse is sent into the engineering structure, and the returned echo signals are examined to derive the maximum amount of information possible about the location, size, and type of any detected flaws. This data can then be used in numerical models to estimate the hazard level posed by the abnormalities, and to monitor any change that has occurred since the previous inspection. Safety is improved and engineering structures can be designed more efficiently.

超声无损检测是一种成熟的表征工程部件和结构缺陷的技术。将高频脉冲发送到工程结构中，并检查返回的回波信号以获得关于任何检测到的缺陷的位置、大小和类型的可能的最大信息量。然后，这些数据可以用在数值模型中，以估计异常造成的危险程度，并监测自上次检查以来发生的任何变化。安全性得到了提高，工程结构的设计也可以更有效率。
