Abstract

Formulas for acoustic channels of ultrasonic testing of products by the tandem method have been obtained and numerically studied for strip-and flat-bottom-type flaws. The choice of optimal parameters for a root-tandem transducer for inspecting the unit of welding of a collector to a ПГВ-1000 steam generator of the ВВЭР-1000 reactor is substantiated.
