Abstract

FIELD: devices and methods for flaw detection. SUBSTANCE: device has transducer 1 having two piezoelectric elements which are high-frequency and low-frequency ones and are connected to channels. Ultrasound echoing signals which are received by piezoelectric elements enters oscillograph indicator 11 through high-frequency and low-frequency channels. Frequency of echoing signals is the same as frequency of synchronization signals. Oscillograph indicator displays whole picture having full information about flaws in tested section of product. EFFECT: increased efficiency and increased reliability of test due to increased size of zone tested during one pass. 2 dwg
