A correction factor for the amplitude adjustment for the pulse echo ultrasonic inspection of components with curved surfaces

Abstract

On the basis of analyzed factors that lead to the amplitude variation of an echo signal from identical reflectors in a quality-control sample and a test sample with curved surfaces, the correction factor for the amplitude adjustment is represented as the product of several factors. Calculation methods are proposed for the components of the correction factor for the case of a curved entry surface of an arbitrary shape and a position relative to the transducer.
