Abstract
PURPOSE: To make it possible to concentrate the ultrasonic beams to a prescribed position and set it to position of a flaw accurately, by detecting gas between a multiprobe and surface of a work to be detected during scanning of the probe, and controlling delay time of transmitting and receiving ultrasonic waves.
CONSTITUTION: Ultrasonic waves emitted from oscillators 11 through 17 and ultrasonic echoes from a flaw on a work being detected are received by the oscillators 11 through 17 and are put into a surface condition detecting circuit 9 and an adder 8 after being passed through preamplifiers 61W67 and delay elements 71W77. The surface condition detecting circuit 9 detects gaps immediately under respective oscillators of the multiprobe and sends these informations to a delay time control circuit 10 and a flaw position setting circuit 31. The delay time control circuit 10 controls the time of transmitting pulses to the oscillators 11W17 and also the time of receiving ultrasonic echoes from the oscillators 11W17 and concentrates the ultrasonic beams to a prescribed position.
