Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO (1) PARA LA ELABORACION DE UNIONES DE CHAPA MEDIANTE SOLDADURA DE COSTURA A TRAVES DE RAYO (78) LASER, DONDE SE COORDINA DE FORMA LIMITADA EN EL LUGAR DE SOLDADURA INMEDIATO DEL RAYO (78) LASER UN ELEMENTO (9) DE PRESIONADO QUE ACTUA SOBRE UNA (79) DE LAS CHAPAS (79,83). PARA OBTENER EN LA SOLDADURA DE RAYO LASER UN RESULTADO DE TRABAJO OPTIMO, ES NECESARIO, QUE POR EJEMPLO EL ESPACIO ENTRE DOS CHAPAS (79,83) A SER UNIDA UNA CON OTRA EN EL LUGAR DE SOLAPE ALCANCE SOLAMENTE UNA PARTE (HASTA APROXIMADAMENTE 0,25) DEL ESPESOR DE LA CHAPA. PARA CONSEGUIR ESTO Y ESPECIALMENTE TAMBIEN ALREDEDOR DE LOS CORDONES DE SOLDADURA CON EL FIN DE PODER ELABORAR LUGARES QUE OFRECEN ESPACIO LIBRE REDUCIDO, NO ACCESIBLE, EL ELEMENTO DE PRESIONADO SE CONFIGURA COMO UNA PARTE (9) DE PRESIONADO EN FORMA DE PASADOR. ESTO PUEDE SER APOYADO ANTES O DESPUES EN LA DIRECCION DE LA COSTURA DE SOLDADURA A SER ELABORADA DEL RAYO (78) LASER.
