Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA CORTE CON LASER DE PIEZAS DE TRABAJO METALICAS, QUE CONTIENE OXIGENO LIGADO MEDIANTE LA UTILIZACION DE LA MEZCLA DE, AL MENOS, UN GAS INERTE E HIDROGENO COMO GAS DE CORTE. LA PORCION DE HIDROGENO DEL GAS DE CORTE PREVIENE QUE EL OXIGENO SEA LIBERADO A PARTIR DEL METAL DURANTE EL PROCESO DE CORTE PARA PREVENIR OXIDACION NO DESEADA EN LA ZONA DEL PUNTO DE CORTE. SE PREVIENE TAMBIEN LA FORMACION DE REBABAS Y SURCOS.
