Abstract

UN MODERNO APARATO DE SOLDADURA LASER MULTIPLE QUE INCLUYE UN ESPEJO FLEXIBLE CAPAZ DE ADMITIR DEFORMACIONES Y RECIBE UN RAYO LASER EN UNA SENCILLA SUPERFICIE DE REFLEXION. LOS MEDIOS DE DEFORMACION FORMAN LA SUPERFICIE REFLEXIVA SENCILLA DEL ESPEJO FLEXIBLE PARA DOTAR UNA DIVERSIDAD DE SUBRAYOS LASER SOBRE LA PIEZA A SOLDAR, QUE GENERA MANCHAS DE LASER EN LA SUPERFICIE DE ESTOS. EL APARATO PUEDE UTILIZARSE EN UN METODO DE SOLDADURA LASER QUE PROPORCIONE UN CORDON DE SOLDADURA COMUN FORMADOS POR RAYOS LASER TRANSVERSALES A LA COSTURA SOLDADA. OTRO SISTEMA DE SOLDADURA LASER PROVEE MULTIPLES RAYOS LASER ORIENTADOS LONGITUDINALMENTE PRODUCIENDO UN CORDON DE SOLDADURA COMUN ENTRE ELLOS. Y TODAVIA OTRO METODO DE SOLDADURA LASER ESTA PROVISTO DE MULTIPLES RAYOS LASER A LO LARGO DE UNA COSTURA SOLDADA PRODUCIENDO DISTINTOS CORDONES.
