Ultrasonic testing through a thickened cladding

This paper presents the results of studies of the effect of thickened repair anti-corrosion surfacing on pre-operational and in-service ultrasonic testing (UT) of the reactor vessel metal through anti-corrosion cladding in comparison with ultrasonic testing through standard surfacing provided for by the design documentation [1]. The paper estimates the distortion of acoustic fields of transducers of transverse and longitudinal waves and the detectability of defects during ultrasonic testing through cladding of different thicknesses and cladding with an inclined fusion zone from a thickness of 11 mm to a thickness of 18 mm
