What Do AWS CWIs Need to Know About Nondestructive Examination?

Certified welding inspectors’ (CWI) work is vital to confirming the safety and quality of the projects they support—but do you know how to properly leverage the insight your无损检测（NDE）reports provide?

作为一名CWI，你可能精通视觉检测（VT），但了解像射线检测（RT）、磁粉检测（MT）或超声波检测（UT）这样的方法，以及它们如何适合你的日常工作范围，将为你的检查增加关键价值。熟悉这些方法和NDE顾问在检查项目时生成的报告对于提供适当的项目监督和确认遵循了适当的测试程序非常重要。

We spoke with our NDE operations manager inLa Porte, Texas, Ken LeBlanc, to ask what every CWI should keep in mind when NDE is used to review your project. Here’s what he said:

1. Know what to expect with NDE
It is important that a CWI have appropriate expectations of the NDE methods employed. Some methods may not identify the defects that are expected due to their inherent limits. Knowing which methods will properly identify expected defects will, ultimately, save your project time and money.

2. Know how to confirm the quality of the NDE work performed
射线图像是最容易验证的。就像看照片一样。焊缝是否在图像上并水平居中？位置标记和图像质量指示器是否存在？图像是非常亮还是非常暗？客户、焊缝和其他要求的识别信息是否清晰可见？虽然这是很多要记住检查，这是一个质量检查，你不需要专门的培训，这将真正有助于确认你的无损检测工作的基本已正确完成。

Similarly, basic checks can be applied to all NDE methods employed. Asking for a copy of the NDE procedure(s) is a good place start. Especially where the record isn’t as easy to review as radiography. Confirming that the service provided is being performed to an appropriate and approved procedure begins with the procedure being documented and easy to review.

CWI没有必要了解程序的有限技术细微差别，以便能够对所提供的无损检测的质量作出公正的判断。如果您不确定您应该寻找什么，我将在即将召开的Braun Intertec网络研讨会上回顾一些常见的CWI NDE检查点示例。manbet体育滚球

3. Know how to review and interpret the results of an NDE report
报告是无损检测非常关键的一部分。除了调查结果的全部细节外，无损检测报告还必须包含正确的日期、工作标识、零件或焊缝标识以及其他代码要求的数据。我还将在我的网络研讨会上详细介绍实际的无损检测报告。
