Complete Your NDT Testing Using Specialized Equipments
The noninvasive techniques help in determining the integrity of material, component or structure; or quantitatively measure some characteristics of an object. In other words, it helps in checking or measuring without doing harm. There are six common NDT methods that you can perform using special NDT testing equipments-
- Visual
- Liquid penetrant
- Ultrasonic
- Magnetic
- X-ray
- Eddy current
Visual inspection is most practiced and fruitful method. For this method, you will require tools – fiberscopes, borescopes, mirrors, and magnifying glasses.
Liquid penetrant inspection is also a great thing to know about the defects. A liquid is used to the part surface and allowed time to seep into surface breaking defects. The excess liquid is wiped off from the surface. Then a powder is applied to make the defect visible on the surface. Visual inspection can be the final step. The liquid penetrant used in the process is often loaded with a fluorescent dye and you can make checks with UV light.
Magnetic particle inspection
The part is magnetized and finely milled dye pigment coated iron particles are applied to the sample. These iron particles are attracted to magnetic flux leakage fields and will develop a cluster. You can detect it visually under good lighting conditions.
You need to make a test report for such experiments by following the report preparation standards. The report must have abstracts, introduction, results, experimental process, discussions, results, and references. The benefits and limitations of every NDT technique need to be stated precisely in your reports. Proper NDT testing equipments should be employed in the testing process for precise results. You should also answer the queries asked by people at the end of the experiment installing the components of your report. It is always good to return the report on time.
