Abstract
EN EL PROCESO PROPUESTO PARA PRUEBA DE ULTRASONIDOS, UN CABEZAL DE PRUEBA DE TEST DE ALTA FRECUENCIA CON UN TRANSDUCTOR DE DIAMETRO IGUAL AL DIAMETRO NOMINAL DE LA SOLDADURA POR PUNTOS A SER INSPECCIONADA SE ACOPLA, A TRAVES DE UNA VIA DE ENTRADA, CON LAS PLACAS EN LA PROXIMIDAD DE LA SOLDADURA POR PUNTOS Y, UTILIZANDO EL METODO DE IMPULSO/ECO, LAS PLACAS SON RADIADAS CON ONDAS DE ULTRASONIDO Y LOS TRENES DE IMPULSO DE ECO SON RECIBIDOS Y EVALUADOS. EN CADA PASO, LA LINEA ESPECTRAL CORRESPONDIENTE AL TIEMPO DE PROPAGACION DE ESPESOR COMPLETO SE EXAMINA PARA UNA AMPLITUD MINIMA SUFICIENTE (DENSIDAD DE ENERGIA) Y PARA UNA AMPLITUD MINIMA SUFICIENTE (AMORTIGUACION).
