Abstract

SE PRESENTA UN APARATO DE SOLDADURA POR LASER (320) PARA SOLDAR POR REVESTIMIENTO LA SUPERFICIE INTERIOR DE UN TUBO (20). EL APARATO INCLUYE UN MANGUITO ROTATIVO (324) QUE SE PUEDE COLOCAR DENTRO DEL TUBO. DENTRO DEL MANGUITO ROTATIVO HAY UN CABLE DE FIBRA OPTICA (340) Y UN ORIFICIO DE PASO PARA UNA SUSTANCIA DE RELLENO (386). EL CABLE DE FIBRA OPTICA RECIBE LA ENERGIA LASERICA PROCEDENTE DE UN LASER (344). EL ORIFICIO DE PASO PARA LA SUSTANCIA DE RELLENO RECIBE EL MATERIAL DE RELLENO PROCEDENTE DE UN SISTEMA DE SUMINISTRO DE METALES DE APORTACION (330) QUE SE MUEVE DE FORMA SINCRONA CON EL MANGUITO ROTATIVO. AL FINAL DEL MANGUITO ROTATIVO HAY UN CABEZAL SOLDADOR (322) QUE INCLUYE UNA APERTURA EN EL CABEZAL (394) Y UN CONJUNTO DE MODIFICACION DE LA DIRECCION DE LA ENERGIA LASERICA (392). LA ENERGIA LASERICA PROCEDENTE DEL CABLE DE FIBRA OPTICA ES TRANSFERIDA A TRAVES DEL CONJUNTO DE MODIFICACION DE LA DIRECCION DE LA ENERGIA LASERICA Y A TRAVES DE LA APERTURA DEL CABEZAL HASTA UN LUGAR DE SOLDADURA SELECCIONADO EN LA SUPERFICIE INTERIOR DEL TUBO. EL METAL DE APORTACION PROCEDENTE DEL SISTEMA DE SUMINISTRO DE METALES DE APORTACION TAMBIEN ES TRANSPORTADO A TRAVES DE LA APERTURA DEL CABEZAL Y ES INTERSECTADO POR LA ENERGIA LASERICA EN EL LUGAR DE SOLDADURA SELECCIONADO. EL METAL DE APORTACION SE FUSIONA CON LA SUPERFICIE INTERIOR DEL TUBO PARA CREAR UNA SOLDADURA POR REVESTIMIENTO.
