Non-destructive testing is a group of surface and volumetric diagnostic tests, which provide information about the functional properties of the tested object. They allow the determination the condition of micro- and macrostructures without causing any interference to their structures .

This basic feature results in the main purpose of non-destructive testing to be the detection of material defects and the evaluation of tested objects for discontinuity and lack of uniformity. Thanks to NDT, it is possible to detect corrosion and erosion defects or cracks.

Non-destructive testing can be carried out at various stages of production, operation, or repair. They are used to perform the quality control of production and to determine the technical condition of the object.

Due to all this, non-destructive testing finds a wide range of applications in various branches of industry. The purpose of this Topic is to present both the development of various non-destructive testing methods, as well as the examples of applications of this group of tests in various branches of industry.
