Non-destructive testing - Advanced

Non-destructive testing - Advanced

When the response to needs for inspection of materials, equipment and structures does not fall in the so-called conventional non-destructive testing techniques (NDT), ISQ uses a range of Advanced NDT. Supported by its R&D department, ISQ has its own ability to develop applications of NDT techniques according to the customer needs. These advanced NDT solutions enable you to store and share data, thereby rendering the dissemination and consultation of results fully accessible to all areas involved, e.g. quality, production and maintenance. The increased sensitivity of this kind of tests and the spatial resolution make inspections more feasible and less dependent on the operator, significantly improving the probability to detect discontinuities.
