METHOD OF ULTRASONIC PRODUCT INSPECTION Russian patent published in 2017 - IPC G01N29/04 

FIELD: measurement equipment.

SUBSTANCE: adding of emitting ultrasound transducer in the product code of the product ensounding ultrasound pulses and receiving the last set of articles of ultrasonic vibrations in the air channel device with the product receiving transducer. Carry out a preliminary ultrasound inspection of the product by a known method to determine the areas where fixed ultrasound passing through the body of the article. Then on one of these sections mounted fixedly emitting ultrasonic transducer selected acoustically opaque product portion to define thereon continuity bonding the polymeric material to the adjacent surface of the housing, as well as articles portion symmetrical to it with respect to the emitting transducer and the forming surface of the article through the place of contact with the emitting transducer surface of the product. Device is oriented by rotating the receiving transducer and movable relative to the longitudinal axis of the article on the surface of the channel portion radially opposite to the selected portion of acoustically opaque. Install the signal level within the screen no upper limit, and still prescribed by emitting ultrasound scan converter receiving transducer portions channel surface of the product, radially opposite the selected acoustically opaque portion and symmetric his site. And sequentially comparing signals on the data portions, identifying the areas where there is a relative decrease in the signal level. After that, the same way others check acoustically opaque areas.

EFFECT: provision of opportunities, quality, reliability and completeness of the ultrasonic control products.
