摘要

The long range objective of the work being performed under this contract is to find a better technique for ultrasonic nondestructive evaluation of elements. The immediate objective is to provide a clearer understanding of the ultrasonic weld inspection technique known as the "Delta Configuration". This technique has been employed for several years, but the approach has been entirely empirical. Work reported in ARMLET 65-84 shows an encouraging potential for the approach. Before further advances could be made, analytical verification of the physics of the sound energy had to be established. Once the path and pattern of the sound energy can be predicted, instrumentation and featuring can be developed which will amplify the merits of this technique.
