ADVANCEMENT OF ULTRASONIC TECHNIQUES USING RERADIATED SOUND ENERGIES FOR NONDESTRUCTIVE EVALUATION OF WELDMENTS.
Abstract
Progress is reported on a feasibility study to determine the physics of reradiated ultrasonic energy and the practicality of using such energies for the inspection of weldments. The use of reradiated energies as used with the Delta Configuration technique has shown promise for weld inspection. The technique is the basis for this study. A literature survey and review was conducted to obtain data with reference to the physics of ultrasonic wave behavior as may be related to the Delta Configuration technique. Also, articles dealing with ways of providing visible ultrasonic waves were reviewed and the data will be used to supplement the analysis of sound waves. An analytical analysis of the sound energy partition has been conducted. The results define the regions where maximum energy is available for use by the Delta Configuration inspection technique. The region of 22 degree to 26 degree angle of incidence, water to steel, is where maximum mode conversion should take place. (Author)
