Ul.trasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse waves with centre frequencies ranging from 0.1-15MHz and occasionally up to 50MHz, are transmitted into materials to detect internal ...

无损检测(Non-destructive testing 简称NDT)，一般包括以下几种: 1、射线检测（Radiography Testing，简称RT） 2、超声波检测（Ultrasonic Testing，简称UT） 3、磁粉检测（Magnetic Testing，简称MT） 4、渗透检测（Penetrant Testing，简称PT） 5、涡流检测（Eddy current Testing，简称ET）

UT（Ultrasonic Testing）工业上无损检测的方法之一。 超声波进入物体遇到缺陷时，一部分声波会产生反射，发射和接收器可对反射波进行分析，就能异常精确地测出缺陷来，并且能显示内部缺陷的位置和大小，测定材料厚度等。

Ultrasonic testing (UT) comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material to characterise the material or for flaw detecting.

Ultrasonic testing is an NDT method that uses high-frequency sound waves to detect and measure discontinuities in industrial components.

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves.

超声波检测（简称ut），是一系列基于超声波在被测物体或材料中传播的非破坏性测试技术。一个常见的例子是超声波厚度测量，它测试对象的厚度，例如，监测管道腐蚀。
