Non-Destructive Tester
(Non-Destructive Testing Specialist)
What Non-Destructive Testers Do
Non-destructive testing specialists test the safety of structures, vehicles, or vessels using x-ray, ultrasound, fiber optic, or related equipment without damaging the materials being tested. They interpret the results of all methods of non-destructive testing (NDT), such as acoustic emission, electromagnetic, leak, liquid penetrant, magnetic particle, neutron radiographic, radiographic, thermal or infrared, ultrasonic, vibration analysis, and visual testing. NDT specialists examine structures or vehicles such as aircraft, trains, nuclear reactors, bridges, dams, and pipelines using non-destructive testing techniques. They identify defects in solid materials using ultrasonic testing techniques and make radiographic images to detect flaws in objects while leaving objects intact. They prepare reports on non-destructive testing results and select, calibrate, or operate equipment used in the testing process. NDT specialists also visually examine materials, structures, or components for signs of corrosion, metal fatigue, cracks, or other flaws using tools such as endoscopes, closed-circuit television systems, and fiber optics.
Education Required
Most employers prefer to hire non-destructive testing specialists with an associate's degree or a degree from a vocational school, although for some entry-level jobs a high school diploma or equivalent may suffice. Many specialists have a background in engineering, aerospace, or other related industries. Training programs in non-destructive testing are available at community colleges, vocational-technical schools, and through specialized NDT training institutes. The curriculum typically covers inspection practices, codes and practices, technical math, blueprint reading, radiographic testing, radiation safety, ultrasonic testing, and technical writing. Certification is essential and follows a three-level system: NDT Level I (entry-level technician), NDT Level II (independent technician), and NDT Level III (management level). Certification requires documented training hours, work experience, and passing written and practical examinations. Vision tests are required annually, and certifications must be renewed every 5 years.
