Available in PDF, EPUB and Kindle. Book excerpt: Present industry-wide standards covering ultrasonic inspections of forgings such as ASTM Recommended Practice for Ultrasonic Examination of Heavy Steel Forgings (A 388-80) specify the contact method of inspection. Sensitivity settings vary as to inspection technique--longitudinal or shear wave (straight or angle beam). Normally, the sensitivity is established using a back reflection or test sample technique in order to resolve equivalent flat-bottom hole (EFBH) sizes of 3.175 mm (0.125 in.) at the centerline or bore surface of the forging. The assumption is made that most indications will be oriented parallel to the direction of the longitudinal axis of cylindrical forgings and in a circumferential plane of ring forgings.
