Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA CORTE MEDIANTE RAYO LASER DE PIEZAS DE TRABAJO EN FORMA DE PLACA O DE BANDA, A ALTA VELOCIDAD, ESPECIALMENTE POR ENCIMA DE 100 M/MIN. EL RAYO LASER FUNDE LA PIEZA DE TRABAJO CON LA FORMACION DE UN CAPILAR DE VAPOR EN EL PUNTO DE CORTE Y LA PARTE FUNDIDA SE GUIA FUERA POR MEDIO DE UN CORTE DE GAS CONSISTIENDO EN UNA MEZCLA DE HIDROGENO/GAS INERTE. PARA MANTENER LA CAPILARIDAD DE VAPOR, EL COMPONENTE DE HIDROGENO DE LA MEZCLA DE GAS DE CORTE SE AJUSTA DE FORMA ALTA, Y ESTA MEZCLA DE GAS DE CORTE ES TOMADA EN LA SUPERFICIE DE LA PARTE FUNDIDA EN EL PUNTO DE CORTE A UNA PRESION TAL, Y A UNA DISTRIBUCION CON TAL PRESION, QUE LA TEMPERATURA EN LA SUPERFICIE DE LA PARTE FUNDIDA SE MANTIENE EN EL PUNTO DE EBULLICION. LA PARTE FUNDIDA ES GUIADA CONTINUAMENTE FUERA DEL RAYO DE CORTE SOBRE EL LADO ALEJADO A PARTIR DE LA DIRECCION DE CORTE DEL CAPILAR DE VAPOR.
