Updated Mar 31, 2022

Non-destructive testing (NDT) is used to inspect or measure the integrity of a material, component, or structure without damaging it. The purpose of testing may be to ensure safety and quality, increase production or extend the life of equipment and system components. Many tests are required by codes or regulations. For example, NDT may be used to test aircraft skins, pipelines, pipes in industrial plants, reinforcing steel in concrete structures, pressure vessels, wire ropes in suspension bridges, steel wheels on trains, or finished machine parts.

Non-destructive testing (NDT) technicians use many different techniques to examine components and parts. Some common types include:

  • Magnetic particle inspection (MPI) - An internal magnetic field is generated in a metal part. Iron particles dusted on the surface reveal flaws located on or near the surface.
  • Liquid penetrant inspection (LPI) - A coloured petroleum or water-based liquid is applied to a nonporous surface. It is then removed and replaced by a white developer. This acts as a blotter and draws out penetrant trapped in voids. The void areas are the flaws.
  • Radiography testing (RT) - Penetrating radiation is absorbed at different rates depending on material density and thickness. It then reveals internal, non-linear flaws, which absorb less radiation. These flaws show up as lighter or darker areas on 2-dimensional radiographic film.
  • Ultrasonic testing (UT) - Complex electronic equipment converts electrical pulses into mechanical vibrations that travel across tested materials. When the reflected pulses are converted back to electrical energy, they create a 3D image of the test specimen.
  • Eddy current testing (ET) - This is a portable method of testing electrically conductive materials. An energized electric coil induces a fluctuating magnetic field that generates an electric eddy current. Changes in resistance to the flow of eddy currents may indicate a flaw in the material. This test can be used on areas ranging from relatively small to vast.

Other techniques can include advanced computer systems, drone, and robotic systems to capture and analyze data in difficult areas, and many more. Opportunities exist for the NDT Inspector to expand their capabilities through continuous learning.

Duties vary depending on the type of test. In general, NDT technicians:

  • Set up and calibrate testing equipment
  • Conduct tests to ensure quality or detect discontinuities (defects)
  • Devise ways to examine objects, ensuring strict adherence to safety regulations
  • Interpret test results using, for example, radiographs and digital readouts
  • Evaluate results according to specifications and standards
  • Organize and report test results

They also may:

  • Perform specialized inspections using acoustic emission, vibration analysis, infrared thermography, or laser shearography
  • Instruct and supervise trainees

Welding inspectors:

  • Review welding inspection procedures against related standards, codes, and drawings
  • Monitor and examine work performed by tackers, welding operators, or welders
  • Verify that the specified base metal and welding materials are used properly and maintained in good condition
  • Verify that joint preparation and fit-up meet requirements
  • Examine and evaluate welds
  • Record inspection results and prepare reports
Working Conditions
Updated Mar 31, 2022
  • Strength Required Lift up to 5 kg

Working conditions vary a lot from one industry and organization to another. Non-destructive testing (NDT) technicians may work primarily indoors in manufacturing or processing plants, or outdoors on construction sites in all weather conditions. They may work shifts. Overtime is often required to complete testing as quickly as possible during plant shutdowns.

Those employed by inspection service companies travel to locations throughout Alberta and across provinces. They may be away from home for extended periods. Their jobs may require international travel .

Occupational hazards also vary. There is some risk of injury involved in working on construction sites and in manufacturing plants. Work at heights, in confined spaces, and in hazardous atmospheres may be required, with proper training. Accidental exposure to radiation is a hazard for NDT technicians who conduct radiographic tests.

Obtaining certification to conduct eddy current, liquid penetrant, magnetic particle, radiography, or ultrasonic tests is an asset for employment.

There are 3 levels of Canadian General Standards Board (CGSB) certification for non-destructive testing that are administered by the Natural Resources Canada (NRCan) National NDT Certification Body (NDTCB):

  • Level 1 personnel perform calibrations and specific techniques according to written instructions and carry out examinations under the supervision and instruction of Level 2 and 3 technicians.
  • Level 2 personnel carry out examinations and interpret results in accordance with established specifications. They are responsible for the method or technique used.
  • Level 3 personnel may assume full responsibility for test procedures and staff supervision. They are qualified to write special procedures, inhouse training programs, and written practices (WP).

To become CGSB NDT certified, applicants must complete training, obtain work experience hours, and pass written and practical examinations.

NDT technicians who conduct tests involving radioactive isotopes must be certified by the Canadian Nuclear Safety Commission (CNSC). To become a Certified Exposure Device Operator (CEDO), applicants must complete or have qualifications equivalent to successful completion of the following:

  • 40-hour Exposure Device Operator (EDO) training program
