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. For example, NDT may be used to test aircraft skins, underground 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 technicians may be certified in any or all of the following types of tests:

  • eddy current - This is a portable method of testing relatively small or vast areas of 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.
  • liquid penetrant - A coloured petroleum or water-based liquid is applied to a nonporous surface, then removed and replaced by a white developer that acts as a blotter and draws out penetrant trapped in voids (flaws).
  • magnetic particle - An internal magnetic field is generated in a metal part and iron particles dusted on the surface reveal flaws located on or near the surface.
  • radiography - Penetrating radiation is absorbed at different rates depending on material density and thickness and is used to reveal internal, non-linear flaws. Flaws absorb less radiation and are indicated on 2-dimensional radiographic film by areas of lighter or darker exposure.
  • ultrasonic - Complex electronic equipment converts electrical pulses into mechanical vibrations that travel across tested materials. Reflected pulses are converted back to electric energy to create a 3-dimensional image of the test specimen.

Duties vary depending on the type of test but, 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 (for example, radiographs, 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 testing methods
  • 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, 2017

Working conditions vary considerably 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 and overtime often is 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 and may be away from home for extended periods. International travel also maybe required.

Occupational hazards also vary. There is some risk of injury involved in working on construction sites and in manufacturing plants. Accidental exposure to radiation is a hazard for NDT technicians who conduct radiographic tests.

  • Strength Required Lift up to 5 kg
Skills & Abilities

Certification Requirements
Updated Mar 31, 2017

In Canada, non-destructive testing (NDT) technicians must be certified to conduct eddy current, liquid penetrant, magnetic particle, radiography or ultrasonic tests.

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.

NDT technicians who conduct tests involving radioactive isotopes must be certified by the Canadian Nuclear Safety Commission. 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
  • Natural Resources Canada EDO exam
  • 320-hour apprenticeship at a licensed gamma radiography facility under the direct visual supervision of an authorized CEDO
  • practical exam.

The Canadian Welding Bureau (CWB) offers 3 levels of certification for Welding Inspectors, progressing from Level 1 to Level 3. Candidates must have job-related experience or have completed recognized welding courses, and pass closed-book, open-book and practical exams. Educational courses are not mandatory for certification. However, candidates who successfully complete CWB Learning Centre study courses receive credits for exams.

The CWB also offers 3 levels of Metal Products Inspector certification for those involved in verifying, qualifying, quantifying and other aspects of products such as buildings, bridges, pipelines, pressure vessels and machinery. Candidates must have related education and practical experience in each product endorsement for which they wish to be certified.

The American Petroleum Institute (API) offers a number of individual certification programs (for example, pressure vessel, piping and above-ground storage-tank inspector certifications). Applicants must successfully complete an exam for each type of certificate.
