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:
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:
They also may:
Welding inspectors:
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.
