How to Become a Non-Destructive Testing Technician

Non-Destructive Testing Technician

Non-destructive testing is the use of scientific and industrial analysis techniques to evaluate the properties of materials, systems or components without damaging them. Non-destructive testing technicians are responsible for implementing these techniques. They mainly focus on examining finished products to establish flows and imperfections that may affect their efficiency and reliability. If you have a background in engineering or science and possess great problem-solving skills, this job could be for you.

The Work

NDT technicians can be found in industries such as power generation, construction and transport where they employ a range of analysis methods, including;

      • Eddy current testing- using the flow of electricity in testing
      • Visual inspection- using lenses and cameras
      • Thermal imaging - used in screening concrete and other building materials
      • Magnetic particle testing-this is used in magnetic components
      • Radiographic testing- using X-rays and radiations
      • Ultrasonic testing-using high frequency sounds in testing and analyzing their echo

Although the specific duties of NDT technicians vary by industry, they generally;

      • Apply any of the methods described above to conduct tests
      • Interpret the methods being used to other personnel
      • Ensure experiment safety
      • Analyze test results
      • Present their findings to senior engineers or managers

Work Environment

NDT technician are normally based in factory production areas, laboratories and workshops where they work from 9am to 5pm, Monday through Friday. Work shifts are available in busy factories.

While at work, these technicians wear protective clothing, such as hard hats and eye shields to avoid injury.
