Nondestructive testing (NDT) is the most important industry you’ve never heard of. That’s how I typically start a STEM (science, technology, engineering, and math) demonstration.

Nowhere is the need for material integrity more obvious than in medical devices that are implanted into human beings. A failed device inside an aircraft or power plant may, under some circumstances, cause a problem.

An important element in ensuring the quality of finished parts is nondestructive testing (NDT). NDT is the inspection of material or parts without impairing their future usefulness.
