ABSTRACT:
A method of ultrasonically inspecting an article comprises the following steps: transmitting a succession of ultrasonic pulses into the article; for each transmitted pulse, detecting and registering electrically the reflected pulse from the front surface of the article; detecting and registering electrically, with a predetermined gain, any reflected pulses indicative of faults or discontinuities within the article; detecting and registering electrically, again with a predetermined gain, at least the first reflected pulse from the rear surface of the article; monitoring the amplitudes of the registered reflected pulse from the front surface and at least the first reflected pulse from the rear surface of the article; and continuously controlling gains for succeeding pulses in dependence on the amplitude of the reflected pulse from the front surface of the article.
