Description
Akustiko-emissionny control allows to reveal superficial and internal defects. The method has rather difficult technology, demands expensive equipment and very high qualification of personnel.

The characteristics defining opportunities, parameters and a scope of an akustiko-issue method is the following: detection and registration only of the developing defects is provided that allows to classify defects not by the sizes, and by degree of their danger; under production conditions the method allows to reveal a crack increment on the tenth shares of millimeter; extreme sensitivity of the akustikoemissionny equipment by settlement estimates makes about 10-6 mm that corresponds to identification of jump of a crack 1 micron long at a size of 1 micron that indicates very high sensitivity to the growing defects; property of an integralnost of a method provides control of all object with use of one or several converters which are not movably installed on a surface of object of control; situation and orientation of defects do not influence their detectability; the method has less restrictions connected with properties and structure of constructional materials than other methods of nondestructive control; the feature of a method limiting its application is in certain cases difficulty of allocation of akustiko-issue signals from hindrances. It is connected with the fact that akustiko-issue signals are noise-type as acoustic issue is casual pulse process. Thereof when signals are small on amplitude, allocation of a useful signal from hindrances represents a complex challenge. At defect development when its sizes approach critical value, amplitude of signals and rate of their generation sharply increase that leads to considerable increase of probability of detection of such source of acoustic issue.

Akustiko-emissionny control is carried out only during creation in a controlled design of the tension initiating work of sources of acoustic issue in object material. For this purpose the design is exposed to loading.
