In all professional fields, certification is a written testimony that proves that an individual is qualified to do certain work. NDT (Nondestructive testing), a technique of paramount importance, too requires a personnel to meet certain qualification standards, which are established by the industry. In most cases, it is the responsibility of the employer to provide NDT certification to his employees.

These certifications are crucial as personnel working in the field often need to make critical judgments that can have safety or significant financial consequences. Another critical fact to be kept in mind here is that many of the NDT methods do not produce a record of the inspection results. This essentially means that one has to completely rely on the skills of the NDT personnel on the job. In such a situation, it is only natural for a person to place his/her trust in someone with a proper NDT certification. Certification presents objective evidence of the knowledge and skill level of the individual performing an inspection.

One of the common courses that come under the ambit of NDT certifications is the dye penetrant testing course. Its objective is to provide the personnel with full theoretical and practical knowledge of PT (penetrant testing) process and related standards in accordance with established procedures.

Advantages Of Using Non-Destructive Testing Methods

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.
