Abstract
SE DESCRIBE UN NUEVO METODO PAR UNIR ALUMINIO A SUPERFICIES DE METAL MEDIANTE SOLDADURA. EL METODO COMPRENDE A) LA APLICACION COMO REVESTIMIENTO A AL MENOS UNA DE LAS SUPERFICIES DE METAL A UNIR DE UNA MEZCLA DE UN METAL (POR EJEMPLO SI, CU O GE) Y UN FLUJO DE SOLDADURA. EL METAL DE LA MEZCLA ESTA ADAPTADO PARA FORMAR UN MATERIAL EUTETICO SOLDABLE CON UNA O CON AMBAS SUPERFICIES DE METAL, B) EL CALENTAMIENTO DE LAS SUPERFICIES Y DEL REVESTIMIENTO EN UNA RELACION YUXTAPUESTA HASTA UNA TEMPERATURA POR ENCIMA DEL PUNTO DE FUSION DE LA ALEACION DE SOLDADURA PARA DE ESTA FORMA DISOLVER UNA PELICULA DE OXIDO SOBRE LAS SUPERFICIES A UNIR, PROVOCAR QUE EL METAL DEL REVESTIMIENTO SE DISUELVA EN EL INTERIOR DE LA SUPERFICIE DE ALUMINIO LIBRE DE OXIDO Y FORME CON LA MISMA UNA CAPA DE ALEACION DE SOLDADURA Y C) EL ENFRIAMIENTO DE LA SOLDADURA PARA FORMAR UNA UNION SOLIDIFICADA ENTRE LAS SUPERFICIES. TODO ESTO TIENE LA VENTAJA DE SUMINISTRAR LA UNION DE SUPERFICIES DE METAL, TALES COMO ALUMINIO CON ALUMINIO, COBRE, LATON O ACERO, MEDIANTE SOLDADURA SIN LA ANTERIOR FORMACION DE UN MANGUITO DE ALEACION DE SOLDADURA SOBRE LAS SUPERFICIES A SOLDAR.
