Abstract

Dispositivo para la verificación volumétrica de las paredes de recipientes o tubos, especialmente para la verificación por ultra sonido de las costuras de soldadura y sus zonas de influencia térmica colindantes en vasijas de presión de reactores nucleares, con cabezas verificadoras de recepción emisión, combinadas (cabezas verificadoras-SE) para recorrer las trayectorias de verificación, caracterizado porque la separación entre los centros de dos cristales osciladores de recepción y emisión o bien contiguos entre si, se ha elegido menor que la separación entre las vías de verificación y esta dimensionada de manera que puede ubicarse por lo menos otros cristal oscilante en el ancho total de la cabeza verificadora, al ser esencialmente iguales entre sí las separaciones entre los centros de los cristales oscilantes contiguos o bien.
