FIELD: machine engineering.
SUBSTANCE: automatic ultrasonic tester contains a moving unit, acoustic unit, electronic unit, power unit and contact liquid tanks. The moving unit includes drive and driven magnetized wheel pairs, a moving drive, moving drive control unit, distometer, rigidly fixed to the driven wheel pair. The acoustic unit comprises of acoustic transducers with phased arrays, and the electronic unit consists of a central control unit, pulse generator, amplifier unit and analog-to-digital signal conversion unit, defect recording unit and signal processing unit. An induction track sensor is rigidly fixed to the drive wheel pair.
EFFECT: improved evaluation precision of metal and weld joint actual state.
