Choosing the parameters of transducers during ultrasonic testing of welded joints by the tandem technique

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 g...

Description
Summary: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.
