Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA PREPARACION DE REGIONES (20) DE COSTURA DE PIEZAS (2,3) DE TRABAJO RECUBIERTAS PARA SOLDADURA (5) DE RAYO LASER, EN PARTICULAR ACERO EN LAMINAS GALVANIZADO, DONDE LAS ESTRUCTURAS SUPERFICIALES DE TIPO MOLETEADO SON ELABORADAS EN LA REGION DE LA COSTURA (20) DE SOLDADURA QUE SUMINISTRA UN ESPACIO (A) ENTRE LAS SUPERFICIES (44,45) DE LA PIEZA DE TRABAJO ADYACENTE. PARA MEJORAR UN PROCESO CON LAS ETAPAS ANTES DESCRITAS DE TAL MODO QUE SE EVITA EL REINTEGRO DEBIDO AL PROCESO MECANICO, EN DONDE EL PROCESO DEBE SER UTILIZADO ESPECIALMENTE TAMBIEN PARA LAS SUPERFICIES DE PIEZAS DE TRABAJO ADYACENTES TRIDIMENSIONALES, LAS ESTRUCTURAS (51,51'') DE SUPERFICIES MOLETEADAS SON ELABORADAS MEDIANTE RADIACION DE ALTA ENERGIA PULSADA.
