Non-Destructive Testing Specialists in Engineering
Overview
Non-Destructive Testing (NDT) Specialists in Engineering check the safety and quality of things like airplanes, bridges, trains, pipelines, and nuclear power parts without cutting them open or breaking them. They use advanced tools such as industrial x-ray machines, ultrasound probes, infrared cameras, magnetic particle testers, and fiber-optic scopes to find hidden cracks, corrosion, or other defects inside metal, concrete, and other materials. They also interpret test data, write detailed reports that must follow strict engineering codes and safety standards, and often lead teams or train new technicians on proper testing methods.

Key Responsibilities
- Select, calibrate, or operate equipment used in the non-destructive testing of products or materials.
- Supervise or direct the work of non-destructive testing trainees or staff.
- Identify defects in solid materials, using ultrasonic testing techniques.
- Develop or use new non-destructive testing methods, such as acoustic emission testing, leak testing, and thermal or infrared testing.
- Document non-destructive testing methods, processes, or results.
- Identify defects in concrete or other building materials, using thermal or infrared testing.
- Produce images of objects on film, using radiographic techniques.
- Map the presence of imperfections within objects, using sonic measurements.
- Prepare reports on non-destructive testing results.
- 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.
- Examine structures or vehicles such as aircraft, trains, nuclear reactors, bridges, dams, and pipelines, using non-destructive testing techniques.
- Evaluate material properties, using radio astronomy, voltage and amperage measurement, or rheometric flow measurement.
- Make radiographic images to detect flaws in objects while leaving objects intact.
- Interpret or evaluate test results in accordance with applicable codes, standards, specifications, or procedures.
- Conduct liquid penetrant tests to locate surface cracks by coating objects with fluorescent dyes, cleaning excess penetrant, and applying developer.
- Visually examine materials, structures, or components for signs of corrosion, metal fatigue, cracks, or other flaws, using tools and equipment such as endoscopes, closed-circuit television systems, and fiber optics.
