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无损检查(NDE)reports provide?
As a CWI, you’re likely well-versed in visual testing (VT) but understanding methods like radiographic testing (RT), magnetic particle testing (MT) or ultrasonic testing (UT) and how they fit into the scope of a your day-to-day work will add critical value to your inspections. Familiarity with these methods and the report an NDE consultant will generate when examining your project is important for you to provide proper project oversight and confirm proper testing procedures were followed.
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
射线照相图像是最容易验证的。这就像看照片。焊缝是否在图像中水平居中?位置标记和图像质量指标是否存在?图像是否非常轻微或黑暗?是客户端,焊接和其他所需的识别信息在图像上清晰清晰清晰吗?虽然这是要记得检查的很多,但它是一个质量检查,您不需要专门的培训,它真正有助于确认您的NDE工作的基础已完成已正确完成。
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还没有必要了解能够对所提供的NDE质量进行公平判断的程序的有限技术细微差别。如果您不确定您应该寻找什么,我将在即将到来的Braun Intertec网络研讨会中查看CWIS的一些共同NDE检查点的例子。雷竞技好Newbee赞助商
3. Know how to review and interpret the results of an NDE report
报告是NDE非常关键的部分。除了详细的调查结果外,NDE报告还必须包含正确的日期,作业标识,部分或焊接识别和其他代码所需的数据。我还将在我的网络研讨会中查看实际NDE报告的详细信息。
