Abstract

Un aparato de ensayo por ultrasonido 100 que comprende una sonda ultrasónica 1 que incluye un número (n > 2) de transductores dispuestos a lo largo de una dirección predeterminada, que se disponen de manera de enfrentar un objeto de ensayo P, y un dispositivo de control de transmisión/recepción 2 para seleccionar un número m (n > m > 1) de transductores de entre el número n de transductores, para transmitir ondas ultrasónicas desde el seleccionado número m de transductores hacia el objeto de ensayo recibir las ondas ultrasónicas provenientes del mismo, y cambiar el número m de transductores a ser seleccionados sucesivamente. Si el ángulo formado entre la dirección de disposición de los transductores y la superficie del objeto de ensayo en el cual entran las ondas ultrasónicas es 0, y el ancho efectivo del haz de cada seleccionado número m de transductores con respecto a un defecto objetivo es W1, el dispositivo de control de transmisión/recepción cambia el número m de transductores que son seleccionados sucesivamente en una longitud de paso de cambio P que satisface la fórmula. P < W1.cos0.
