Abstract
Método perfeccionado para la detección de grietas y fisuras superficiales en una pieza de trabajo metálica, caracterizado porque la superficie de la pieza es calentada por medio de una corriente de alta frecuencia, de modo que las posibles grietas y fisuras superficiales mostrarán un diseño de franjas que indica el perfil de temperaturas a través de la pieza y que, de nuevo, es registrado por medio de un equipo de registro de infrarrojos.
