ULTRASONIC TEST PROCEDURE FOR RATING INTERNAL CLEANLINESS OF SEMI-FINISHED MATERIAL.
Abstract
An investigation was conducted to evaluate and standarize upon various ultrasonic instrument and operational parameters which may alter inspectional response in the detection of nonmetallic inclusions and cleanliness rating of semi-finished material. In order to obtain an acceptable degree of uniformity of test results between various laboratories, recommendations are presented with regard to specimen preparation, instrumentation requirements, search unit specifications, system calibration, inspection procedure and data processing.
