introduction to NDT Certification

‘Certification’ in NDT is a written document indicating that an inspector has required skills to perform nondestructive testing in the method. He should have capability to carry the tests as per approved procedures. It also gives confidence to the customers that he/she has met requisite educational qualifications, and experience. Based on the level certified, inspectors should have competency to perform inspections and interpret examination results.

Why an NDT Inspector should be certified?

Unlike destructive testing, in NDT, interpretation of results are not easy. For example in destructive tests, such as tensile or hardness testing the results are directly readable from gauge or screen. Where as in NDT, results are not directly readable, thus demands additional competence in evaluation. Therefore, standards and codes mandates that the inspector should meet education, experience and training. In almost all cases, the inspectors should have either Level I or II or III certification in the test method.

Unless the inspector has met the qualification criteria he/she shall not be engaged in any NDT activities. Because, there is no assurance that the candidate has adequate skills to interpret the results, it is risky to accept results.


Trainee in NDT

A candidate before certification is considered as ‘NDT trainee’. He/she has to work under the supervision of either Level I or Level II. Shall not perform the testing independently.

As per SNT TC 1A, ‘A trainee is a individual being trained and yet to be qualified and certified’. He should work with a certified Level 2 or 3 person. Also, states that he shall not conduct, interpret, evaluate and report the examination results without the supervision.

NDT Level I and Level II Inspector

Level I certification gives assurance that the inspector has ability to do equipment calibrations. He/she should able to perform testing as per approved NDT procedures.
In contrast, Level II inspectors, should have skills for interpretation and evaluation of indication. He/she shall have knowledge about NDT codes and standards. Prepare written instructions for Level I in the method certified. He is responsible for maintenance of equipment and accessories.

Reviews, Feedback on NDT Certification

Mr Pradeep Kumar from Patna(Bihar) says, “I am previledged to pursue my NDT level II certification. Special thanks to Mr.Ravi sir, Mr.Shiva sir and all training coordinators for support. I really enjoyed each and every moments here and learned many things. I would recommend my friends and colleagues to Trinity NDT for level II and welder certification.”

We profusely thank individual from Patna, Bihar for choosing our NDT training. He traveled all the way to the institute, successfully undergone the certification. He is presently working as NDT Level II inspector near Patna. Since earlier days of establishing the training center, we trained and certified at least hundreds of engineers from Patna, Siwan in Bihar. Institute also has instructors with Hindi speaking. This helped non English speaking engineers from Northern states of India such as Bihar and Jharkhand.

Organizing special practical training for non-English speaking personnel. We believe language should not be a barrier for learning NDT. Our courses helped engineers from Patna and Siwan for NDT Level II certifications.

Prof. Ravi Shankar K, faculty at IIT Madras(Chennai) expressed that “Perhaps, this is the best NDT and Welding training center in South
India. Their training in welding and NDT are unique and provide a rich experience to practicing engineers. Also, due to their extensive
in-house NDT testing infrastructure, they are the best in south India.”

We thank the professor for his views about the training center. Though institutes in Chennai offers NDT Level II courses, quite a few offers training on modern equipment under expert ASNT Level III trainers. Chennai is hub for core mechanical jobs, we seamlessly connect with them with right employers in Hosur, Coimbatore in Tamilnadu.

A candidate Mr Rajesh from Mangalore writes that “I have joined this institute to take NDT training & knowledge purpose. My experience is excellent. Specially good NDT laboratory.”
