Non-destructive testing, a type of testing that doesn’t cause any damage to construction or quality of a product, has been there for a long time. You may not have noticed its beginning and development, but NDT has been there long enough. However, you can say that these testing methodologies have a become a lot more robust over the years. Some of NDT methods include liquid penetrant testing, magnetic particle inspection or testing, ultrasonic testing, eddy current testing, etc. And if we look at the benefits of NDT, they have also improved over the years. While you could have only thought of a few of these benefits when these methods were launched, everyone who uses these techniques for one reason or the other has come to expect these advantages now.

One of the major reasons why non-destructive testing is employed is to test the quality/integrity of a product – to learn whether it is completely compromised or a repair could help it in keeping its standard properties. The improvement in the safety of the tested product, as well as the tester, is always one of the things that you have at the back of your mind when using NDT. You know that it is going to maximize safety. To put it in other words, all of NDT methods don’t damage the tested product in the least bit, most of them have no negative impact on humans, with the exception of radiographic testing, which has to be conducted under strict supervision. For industries that employ high-pressure or volatile machinery, NDT often comes across as a testing method that provides a safe environment for all the people involved.

The reliability of results is another advantage that makes NDT so popular for various applications. And this accuracy is often put down to the available and complementary testing alternatives that NDT brings with it. The risk of inaccuracy or oversight could be completely taken care of by subjecting the tested product to a variety of tests.

As you would agree, different applications follow a different rulebook when it comes to ensuring safety standards. Also, the machinery employed in different industrial settings has to be inspected on a regular basis. Non-destructive testing is the most cost-effective inspection method, be it any product or industry. Destructive testing techniques will always incur a significant amount more than NDT. So, in most cases, NDT comes as the most suitable option.
