Sensitivity trimming in testing austenitic welds

A method for sensitivity trimming during testing of welds by the bottom signal is recommended. A technique for sensitivity correction when changing from the separate to the transceiving operating mode is suggested. During the testing of austenitic welds, this technique allows taking into account the ultrasound attenuation in the built-up metal of a joint and checking of the testability with allowance for the weld structure.Translated from Defektoskopiya, Vol. 41, No. 1, 2005, pp. 3–9.Original Russian Text Copyright © 2005 by Ermolov, Vopilkin, Grebennikov, Samarin.
