  • Use scientific methods to test materials and components in machines to make sure they are safe
  • There are a wide range of specialist areas, and this work is in-demand
  • You'll need great maths and science skills

As a non-destructive testing technician, you'll be involved with quality control procedures in aerospace, energy, manufacturing and transport. You'll test materials used in machinery and structures to find faults like corrosion, cracks, flaws and other imperfections.


  • Visually inspecting materials using CCTV and fibre optic cameras
  • Conducting thermal imaging to find defects in concrete and other building materials
  • Dye testing to stain surfaces with fluorescent liquid magnetic
  • Magnetic particle testing (applying magnetic particles to materials)
  • Radiographic testing by using X-rays to find internal faults
  • Ultrasonic testing using high frequency sound pulses with materials
  • Eddy current testing electricity through materials
  • Resonant testing which is 'listening' to the growth of cracks or flaws by monitoring the acoustic vibrations of a structure
