Ultrasonic Inspection of Aircraft Forgings
SourceUltrasonic inspection, one of the newest methods of nondestructive testing, has grown in a relatively short time from a laboratory phenomenon to one of our most valuable means of detecting subsurface discontinuities. Ultrasonic flaw detection, basically speaking, employs a high-frequency sound wave which, when transmitted into a piece of material, follows a linear path and is reflected back when it reaches the end face of the material or an internal discontinuity. In plate, bar, and extrusion, the subsurface defects lie parallel to the surface, almost without exception, and these materials readily adapt themselves to high-speed scanning and the use of automation and automatic scanning equipment.
