Nondestructive Testing and Evaluation of Steel Bridges
نویسنده
چکیده
Nondestructive evaluation (NDE) is a means of evaluating structural components without damaging them. It can be used to evaluate structural systems, as well as specific structural components. Nondestructive testing is particularly useful for evaluating inservice bridges, since the bridges can remain in tact and open to traffic during the inspection and evaluation period. The NDE methods discussed in this paper include visual inspection, eddy current method, radiographic testing, and manual and automated ultrasonic testing. The Federal Highway Administration’s NDE Validation Center performs extensive research on a number of these NDE methods.

متن کاملDesign of Nondestructive System for Hardness of Carbonitrided Steel Parts Using Eddy Current Testing Method: Case study on the Tappet Parts
In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...
