Abstract

UN PROCESO ESENCIALMENTE SOLDADOR SIN FUNDENTE PERMITE QUE UN REVESTIMIENTO SOLDADOR SE PUEDA APLICAR A LA SUPERFICIE BAJO CONDICIONES CONTROLADAS DE PRESION, PERMITIENDO QUE EL VOLUMEN Y FORMA DEL SOLDADOR SEA CONTROLADO A VOLUNTAD. LOS REVESTIMIENTOS PRODUCIDOS POR PROCESOS SIN FUNDENTE PERMITE QUE LOS PROCESOS DE UNION SE PUEDAN EFECTUAR DE UNA MANERA ESENCIALMENTE SIN FUNDENTE CON GRAN FLEXIBILIDAD DE PROCESADO.
