无损检验的分类应用及效益分析

Classification,Application and Benefit Analysis of Nondestructive Testing

无损检验在检测材料内部机械结构强度的同时,对设备的外观及结构强度无影响,不会损伤材料内部的金相形式,且能够检测材料内部损伤的形状、尺寸、位置和分布等。鉴于此,重点从无损检测类别说开去,详细介绍UT检测、MT检测、PT检测、直探伤UT检测的内容和特点,以及不同检测报告适用的推荐场合,并分析无损检验为企业带来的效益。

Non-destructive testing has no impact on the appearance and structural strength of the equipment while detecting the strength of the internal mechanical structure of the material.It will not damage the metallographic form of the internal material,and can detect the shape,size,location and distribution of the internal damage of the material.In view of this,this paper focuses on the NDT category,introduces in detail the contents and characteristics of UT testing,MT testing,PT testing,and direct flaw detection UT testing,as well as the recommended occasions for different test reports,and analyzes the benefits of NDT for enterprises.
