NDT stands for Nondestructive Testing and depending on the industry can sometimes be referred to as NDE (Nondestructive Evaluation) or NDI (Nondestructive Inspection). NDT offers the ability to verify the integrity of a part without damaging or destroying it.

NDT is a critical component of many industries, from aerospace and oil and gas to automotive and electric utilities. Since the early 1900’s, NDT has become one of the leading technologies for a wide variety of areas, ranging from quality control of products to preventive maintenance of in-service parts.

NDT Candidates can expect high earning potential and TXNDT graduates can always attend additional classes to obtain further qualifications and increase their earnings substantially. Certified NDT Technicians should anticipate compensation packages to include full insurance benefits and substantially high wages, depending on their course of study and industry employed in.

To become certified in a NDT method, you must complete training hours, on the job training (minimum experience requirements), and pass physical, general, specific and practical exams.

Absolutely! The Non-Destructive Testing and Inspection industry has been (for the last century) and will be a growth industry for decades to come. As the infrastructure of America ages, the need for evaluation and advanced examination techniques increases. NDT and inspection are not job avenues. They are careers.

Great question! That depends on an employer’s requirements for qualification which can be found in their written practice. Most companies written practice include a combination of training hours and examinations to qualify personnel. If written per SNT-TC-1A recommended guidelines, the following table lists those guidelines.

Method Level I Level II Total Training Hours
Magnetic Particle 12 8 20
Liquid Penetrant 4 8 12
Ultrasonic Testing 40 40 80
Visual Testing 8 16 24
Furthermore, SNT-TC-1A recommends the following examinations:
  • General Exam – Covers the basic principles of the applicable method.
  • Specific Exam – Covers the procedures, equipment and techniques required to perform in method.
  • Practical Exam – This Hands On exam shows an employee’s ability to operate equipment, to perform calibrations and to identify flaws in a test specimen.
  • Visual Exam – Performed annually, proves near vision acuity and color differentiation.

Training Hours and Exams are the first two parts. On the job time in method under the supervision of a certified individual is the third and final piece to the puzzle. All the time spent calibrating, testing, reporting and observing count towards time in method. Check out TXNDT Labs for some options to work on accruing your time in method today.

The following is the SNT-TC-1A Recommended Time in Method

Method Level I Level II Total Time in Method
Magnetic Particle 70 210 280
Liquid Penetrant 70 140 210
Ultrasonic Testing 210 630 840
Visual Testing 70 140 210

Once all qualifications are met, then it becomes the responsibility of the employer to certify an employee.
