INVESTIGATION OF THE FRONTAL RESOLUTION OF AN ECHO-TYPE FLAW DETECTOR

An analysis is made of the resolution for an echo-type flaw detector when inspecting with straight, combination probes. A formula is derived for the variation of the echo-signal amplitudes from two flaws located at the same depth which have different reflection areas. A program was written for the MIR digital computer, and the variation of the echo signal was calculated and confirmed experimentally for a wide range of dimensionless parameters both along a line connecting the two flaws and at an angle to it.
