Title:
METHOD AND DEVICE FOR NONNDESTRUCTIVE ULTRASONIC EXAMINATION
Document Type and Number:
Japanese Patent JPS568546
Kind Code:
A
Abstract:
A method for ultrasonic fault localization, in which the fault is determined from the travel time of the ultrasound pulses and the echo pulses, in which an echo pulse reflected in the workpiece at a fault is received at three different points on the surface, the electronic echo pulses are electronically added in phase with a delay dependent on the different propagation times, and fed to an electronic time window such that during the open time of the time window, only echo pulses from the fault are picked up. The fault is displayed graphically as to size, position and shape.
