Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA VERIFICACION POR ULTRASONIDOS DE PASADORES CON UN SALTO EN EL ESPESOR DE PARED CON RESPECTO A GRIETAS QUE PARTAN DEL MISMO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, EL EMISOR Y EL RECEPTOR PARA ONDAS DE ULTRASONIDOS, SE APLICAN SOBRE EL LADO MAS GRUESO DEL PASADOR, SOBRE SU PERIFERIA, DE TAL FORMA QUE EL SALTO DE ESPESOR DE PARED SE ENCUENTRE EN LA ZONA DEL CAMPO PROXIMO; SEGUNDA, SE IRRADIAN CON EL EMISOR ONDAS DE ULTRASONIDOS HACIA EL SALTO DE ESPESOR DE PARED; Y POR ULTIMO, LA INTENSIDAD DE LAS ONDAS REFLEJADAS SE COMPARAN CON UNA CURVA CARACTERISTICA DE ECO QUE SE HA OBTENIDO CON UNA PROBETA CORRESPONDIENTE AL PASADOR A VERIFICAR, CON ACANALADURAS QUE SIMULAN GRIETAS DE PROFUNDIDAD VARIABLE.
