FIELD: measurement equipment.
SUBSTANCE: application: for non-destructive check of a tested object material with the help of ultrasonic waves. The invention concept is as follows: the invention consists in the fact that the following stages are performed: subdivision of a tested object (10) with computer support into predetermined number of volume elements (30); loading of a tested object (10) with a sound field (14) during scanning of a surface or at least a section of a surface of the tested object (10); registration of sound waves reflected on volume elements during scanning of a surface or at least a section of a surface of a tested object (10); summation of sound waves, with account of phase, reflected at same volume elements (30) and registered on different measurement positions (22, 24, 26) on a surface of a tested object (10), at the same time in each measurement position (22, 24, 26) a central beam (16) is directed to a volume element (30), besides, the central beam (16) has maximum intensity of a sound field (14), and multiple edge beams (18) have, accordingly, a half of maximum intensity of the sound field (14), and moreover, when programming orientation of a feeler (12) the direction-dependent sensitivity is taken into account already at the stage of measurement due to the fact that angle-amplitude correction (AAC) is established.
EFFECT: increased extent of validity of object non-destructive check.
