DETERMINATION OF DEFECT GEOMETRY BY ULTRASONIC PULSE ANALYSIS TESTING
Abstract
Test specimens containing artificial defects of various configurations were consecutively subjected to a conventional ultrasonic pulse echo test and a novel pulse reflection method employing polychromatic ultrasonic energy. Results are compared from the viewpoint of the effectiveness of these two methods to differentiate among various flaw geometries. It was found that the polychromatic pulse method permits a more conclusive geometry inspection for defects which are smaller than the ultrasonic search beam diameter. (Author)
