Non-destructive testing (NDT)
Testing of materials is important, primarily in a field of increasing quality and reliability of products. NDT finds application especially in the machine industry. Non-destructive methods occupy a special position because they ensure that the material and its mechanical properties are not damaged. The existing non-destructive methods are based on the principle of detection of changes caused by inhomogeneities inside the material (fissures, ruptures, shrinkage cavities, holes, inclusions, etc), either in magnetic fields, eddy currents, optical changes or, last but not least, acoustic waves.
