Abstract

UN METODO PARA SOLDAR SIN LA NECESIDAD DE AGENTES DE FUSION, DE ALTA TEMPERATURA, DE HIDROGENO, DE EXCITACION LASER O TECNICAS DE CHISPORROTEO. EL METODO UTILIZA EXCITACION DE PLASMA PARA ELIMINAR LOS OXIDOS SUPERFICIALES DE LAS SUPERFICIES DE SOLDADURA, CON LO QUE SE ELIMINA LA NECESIDAD DE LA LIMPIEZA POSTSOLDADURA DE UNA MANERA EFICAZ Y PRECISA, CONSIGUIENDO UNA MAYOR CALIDAD Y UNA FIABILIDAD DURADERA DE LA SOLDADURA. ADEMAS, SE EVITAN LOS SERIOS PROBLEMAS AMBIENTALES QUE CAUSAN LOS DISOLVENTES DE LIMPIEZA.
