Abstract

CUANDO UN TRANSDUCTOR ULTRASONICO PARA DETECTAR DEFECTOS EN PLACAS DE METAL O EN LA PARED DE UN CILINDRO DE METAL SE DIRIGE A UNA SUPERFICIE A INSPECCIONAR CON UN ANGULO PARTICULAR, ALREDEDOR DEL 10% DE LA SEÑAL APARECERA COMO ONDAS DE HARRIS QUE SE PROPAGAN HACIA EL INTERIOR DE LA PLACA DE COMPROBACION CON UN ANGULO DE 90° CON RESPECTO A LA SUPERFICIE. ESTA SEÑAL QUE SE PROPAGA VERTICALMENTE ESTA POLARIZADA, CON EL RESULTADO DE QUE LA SEÑAL TIENE UNA RELACION DE SEÑAL/RUIDO GRATAMENTE MEJORADA. PARA UN MEDIO INCIDENTE DE AGUA Y EMPLEANDO UNA ONDA DE CORTE QUE SE REFRACTA EN EL MEDIO DE HIERRO FUNDIDO EL ANGULO ESPECIFICO ES APROXIMADAMENTE DE 33° A PARTIR DE LA VERTICAL PARA UN MEJOR RELACION DE SEÑAL/RUIDO. PARA EL ACERO EL ANGULO ESPECIFICO ES APROXIMADAMENTE 31° Y ES DE ALREDEDOR DE 50° PARA EL LATON. PUEDEN EMPLEARSE ONDAS DE CORTE O LONGITUDINALES PARA INFLUIR SOBRE LA DETECCION DE LOS DEFECTOS DEL SUBSTRATO CON EL ANGULO PARTICULAR CAMBIANDO DEPENDIENDO DE LA RELACION DE LA VELOCIDADDE LAS ONDAS SONORAS EN EL MEDIO DE REFRACCION CON RESPECTO A LA VELOCIDAD DE LAS ONDAS SONORAS EN EL MEDIO INCIDENTE.
