NDT TECHNICIAN


Job Description

Non-destructive testing technicians use different scientific methods to test the properties of materials, components and systems without causing damage.

You would be working with scientific technology so you would need to have a good understanding of health and safety issues. Non-destructive testing (NDT) technicians  also need to have an eye for detail when analysing the results of tests.

There is no set route to become a non-destructive testing technician. Many new technicians get into this role through apprenticeships or by studying towards a certificate or diploma in engineering and applying for trainee positions.

Non-destructive testing (NDT) technicians examine and test the physical properties of materials and components to find possible corrosion, cracks, flaws and other imperfections, which could affect their performance and reliability. They use testing processes that do not damage the structure of the object being tested.

In manufacturing, you would work with materials at every stage of production to make sure they are safe. For example, in aircraft construction, you would test materials when they are first made, while the fuselage is being built, and at regular intervals throughout the operating life of the aircraft.

NDT methods are also used in quality control procedures in many industries, including, aerospace, road and rail transport, manufacturing and power generation.

An important part of your work would be to make sure that the testing method you use does not have any harmful effect on the materials, parts or machinery under examination.

Job Duties/Responsibilities

  • eddy current testing – passing electricity through materials and measuring the differences in the flow of current
  • resonant testing – 'listening' to the growth of cracks or flaws by monitoring the acoustic vibrations of a structure, for example a bridge support.
  • dye testing – staining surfaces with fluorescent liquid, which shows up flaws under ultraviolet lighting
  • magnetic particle testing – applying magnetic particles to magnetised materials, so they line up along cracks and defects (often combined with dye testing)
  • visual inspection – using lenses, CCTV and fibre optic cameras
  • thermal imaging - used to find defects in concrete and other building materials
  • radiographic testing – using X-rays to find internal faults
  • ultrasonic testing – firing high frequency sound pulses into materials and analysing the differences in the reflected signals
