Abstract
The British Steel Corporation has developed an experimental ndt system for the ultrasonic inspection of steel blooms and billets at elevated temperatures to detect piping and segregation using a momentary-impact pressure coupling technique. The apparatus comprises a steel head assembly mounted for reciprocating movement. Two ultrasonic transducers, one for transmission and the other for reception, are mounted on a split head separated by an acoustic attenuator. The head is reciprocated in such a manner as to cause impact upon the sample with an impulsive blow of short dwell time (< 400 μs), once during each reciprocation of the head. An application has been made for a patent.
