Introduction

If you have an eye for detail and a passion for ensuring safety and quality in various industries, a career with Non-destructive Testing (NDT) qualifications might be the perfect fit.

NDT inspector certification plays a critical role in ensuring that structures, equipment, and materials meet industry standards without causing damage.

For those who are not familiar with NDT Testing Certification, let us clear it up for you. So, it can be defined as a written or authorized document that indicates an NDT Technician has all the needed skills to perform NDT Methods.

He or she should be well equipped with the capability to conduct the tests according to the approved Non-destructive Testing Standards.

It also gives the consumer confidence that they have fulfilled the required educational qualifications without modification.

To be competent to conduct NDT Certification level 2 and NDT level 1 Inspections, one must have the competency to carry out inspections and interpret the results of the NDT Training and Testing Center

Why is NDT Important?

Dissimilar to destructive testing methods, in Non-destructive Testing, the interpretation of outcomes is not that simple.

For instance, when it comes to destructive tests, such as hardness testing or tensile testing, the outcomes can be read directly from the screen.

On the other hand, the outcomes cannot be read easily in NDT Services

Hence, it demands extra attention or time while doing examinations by the Best NDT Professionals.

Therefore, standards and codes grant that the inspector must complete Non-destructive Testing Courses, training, and level of experience.

In almost every case, the NDT Inspectors should hold either Level I, II, or III certification in the examination method.

Until and unless the inspector has met all the required qualification criteria, they must not be allowed to be engaged in any NDT Types of Equipment.

This is so because there is zero to little assurance that the candidate has the proper skills to interpret the outcomes, and it becomes highly risky to accept those results.

Before acquiring a certification, a candidate is known as a trainee and is expected to have the best NDT Techniques.

A trainee has to function or work under the proper guidance of either Level I or Level II while using the NDT Equipment appropriately.

How do I become NDT Certified?

It is a formal recognition of an individual's competence in conducting Non-destructive Tests, ensuring the reliability and safety of materials and structures.

There are many Non-destructive Testing Certification courses and there is a lot of scope in NDT. 

According to the ASNT instructed practice SNT TC 1A, ISO, and NAS410, there are 3 levels of NDT Certification, as mentioned below:

1. NDT Level I — A technician that performs actual tests as per Level II or III Instructions. You can also get more information about the NDT Level I Course Fee and Duration at OnestopNDT
