Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA IDENTIFICAR INSUFICIENCIAS EN PIEZAS DE TRABAJO LARGAS, ESPECIALMENTE EN TUBOS Y VARAS, MEDIANTE ULTRASONIDO. LA PIEZA A COMPROBAR (2) SE HACE PASAR, EN DIRECCION AXIAL Y SIN GIRARSE, JUNTO A UN TRANSDUCTOR ELECTRODINAMICO (1). ESTE GENERA EN LA PIEZA IMPULSOS ONDULADOS (A,B) QUE SE EXTIENDEN TANGENCIALMENTE Y EN AMBAS DIRECCIONES PERIFERICAS POR EL PERIMETRO DE LA PIEZA. ESTOS IMPULSOS SON SELECCIONADOS DE MANERA QUE INTERFIERAN DESTRUCTIVAMENTE EN EL SITIO (3,4) DEL RECEPTOR. POR CONSIGUIENTE, UNA PIEZA (2) SIN DEFECTOS NO PRODUCIRA NINGUNA SEÑAL EN EL RECEPTOR. SEGUN EL INVENTO, LA SEÑAL DE RECEPCION Y LA SEÑAL DESTRUCTIVA CUYO PERIODO ES AJUSTADO COMO INFERIOR A UNA CUARTA PARTE DEL TIEMPO DE UN RECORRIDO PERIFERICO DEL IMPULSO ONDULADO POR LA PIEZA, Y CUYA DURACION CORRESPONDE AL TIEMPO DE ATENUACION DE LOS IMPULSOS ONDULADOS SIN INTERFERENCIAS DE UNA PIEZA SIN DEFECTOS, SE TRANSMITEN A UN DETECTOR DE PICO; LA SEÑAL DE SALIDA SE DIGITALIZA Y SE TRANSMITE A UN ORDENADOR.
