Application of Ultrasonic Method for Non-Contact Control of External Defects of Metal Surfaces
Ch. 6. P. 349-351.
The paper considers a non-contact method of
controlling external defects of metal surfaces. The differential
method of processing information obtained by ultrasonic echomethod
from different measuring channels is used.
Mathematical modelling of offered method has demonstrated
its practical application. The structure of intelligent measuring
device was proposed, a schematic diagram was developed and
a prototype of the sensor was assembled. Tests have proved
possibility of determining of small defects of metal surfaces.
