Non-destructive testing (NDT) is an engineering practice that covers a diverse group of analysis techniques. These techniques, under the umbrella term of NDT, are used to inspect, test and evaluate properties of a material, component, or system for discontinuities and differences in characteristics, such as breaks or cracks, without causing damage or preventing the part or system from functioning properly. This therefore makes NDT economically valuable for a wide range of companies, including the automotive industry, mining, and offshore drilling.
NDT methods include magnetic particle testing, ultrasonic testing, eddy current testing, and ACFM testing. Depending on which method is performed, materials that can be tested on include metals, concrete, ceramics, wood and plastics. In addition, NDT can also be used for in-service inspections to ensure product integrity, safety and reliability, including product compliance for castings, forgings, welds, and other wrought products.
The flexibility of NDT allows it to be the preferred analysis testing by industries in science, manufacturing, mining, and fabrication. Aside from the economical component, NDT also provide companies and industry with reliable and accurate testing. It is important to make mention here at all NDT methods can only be conducted by a fully qualified and certified professional according to international guidelines.
