Application of Ultrasonic Testing by Image Technoques to Electronic Parts and Weldment Structures

摘要

Ultrasonic testing (UT) by image techniques was developed, by which the flaws can be displayed in B or/and C-scope in two dimension and 3D-scope in three dimension. By utilizing the image techniques, the size, shape, location and distribution of the flaws can tbe identified as images with high accuracy. In this paper, outlines of newly developed image systems are described and applications to electronic parts and so on are shown as well.
