BONDING METHODS AND A BONDING CLAMP FOR ULTRASONIC MEASUREMENTS.

摘要

The results of an investigation conducted to improve bonding techniques between the transducer and specimen in ultrasonic measurements are presented. Two major coupling agents,glycerin and phenyl salicylate,were subjected to tests. As a result of these tests a bonding clamp was developed which greatly increased the reproducibility and accuracy of measurements. A new bonding method using glycerin and oil is reported.
