| 中文摘要: |
| 焊接是工业生产过程中机械零部件连接的一种常用方法，近些年来对焊接质量的要求日渐提高，而无损检测技术的出现使焊接件的质量得到了有效可靠的保证，该技术不会破坏焊接件的使用性能，利用该技术可以对焊接缺陷进行评定检测，从而对焊接质量进行有效控制。近年来，无损检测技术日渐多样化，对较新型的超声波衍射时差法(TOFD)、发射检测(AE)、脉冲涡流检测、超声相控阵检测(PAUT)等焊接无损检测技术做了研究和探讨，可为实践应用提供依据。 |
| 英文摘要: |
| Welding is a commonly used method for connecting machinery parts in industrial processes. In recent years, the demand for welding quality increases, while the emergence of non-destructive testing technology guarantees quality of welding parts reliably. This technique can detect and assess welding defects without affecting the using performance of welding parts, so that the welding quality can be controlled effectively. In recent years, the non-destructive testing technologies are diversified. The newer welding nondestructive testing technologies such as TOFD, AE, pulsed eddy current testing, PAUT and so on are researched and discussed in the paper, which can provide a basis for practical application. |
