Abstract
An arrangement for the non-destructive testing of articles in which a head, carrying at least one ultrasonic testing transducer, is caused to reciprocate so as to impact upon the article to be tested with an impulsive blow of short dwell time once during each reciprocation, the transducer element carrying out a testing operation during the dwell time of each impact.
Claims15
Apparatus for the non-destructive testing of articles comprising a head mounted for reciprocating movement;
- ultrasonic testing transducer means mounted on the head;
- means for reciprocating the head such that in use the head is caused to impact upon the article to be tested with an impulsive blow of short dwell time once during each reciprocation of the head;
- and means for actuating the transducer means for testing operation by the transmission of pulses and the reception of pulse echoes through the contacting area of the head and the article to be tested during the dwell time of each impact.
A method of non-destructively testing articles comprising repeatedly impacting a head carrying ultrasonic transducer means with an impulsive blow of short dwell time upon different portions of an article to be tested, and actuating the transducer means for testing operation by transmission of pulses and the reception of pulse echoes through the contacting area of the head and the article to be tested during the dwell time of each impact.
