Introducing Young People to NDT

An article by Phillip W. Trach, published in Materials Evaluation and entitled “Introducing Young People to NDT,” is featured in a special section on NDT Education and Training. It provides an overview of how to prepare, practice, and present an introductory lesson in nondestructive testing (NDT) suitable for a school classroom.

With an aging population of nondestructive testing practitioners and limited opportunities for school students to become exposed to a career in NDT, it becomes necessary to actively recruit and train young people to fill open positions as the current workers retire. 

Phil’s article first explores the process of constructing a lesson plan, which not only explains what will be taught but also why it is worthwhile for students to learn about nondestructive testing. He also offers suggestions for presenting the lesson to students of various ages from his own experiences.

While preparing the lesson, Phil keeps the question, “Why is it important,” as his theme throughout. Examples of possible lesson approaches include:

• Telling stories
• Demonstrations
• First principles
• Coordination with the existing curriculum

As stated by Phil, “Demonstrations can be very effective, especially when students can try the equipment for themselves.” He also notes that you should have your lesson organized and be able to expand on your lesson with specific details.

Nondestructive testing is used to inspect material and component parts for flaws and inconsistencies without causing damage. Ultrasonic testing, magnetic particle inspection, liquid penetrant testing, X-ray inspection, and hydrostatic pressure testing are performed at LTI. These test methods are available for inspecting tubing, pipes, bars, plates, castings, fasteners, and other metal products, as well as some ceramics and plastics.
