Abstract

Método para unir conjuntamente por soldadura fuerte las pletinas de reja de una reja de un conjunto de combustible nuclear estando dicha reja ensamblada de tal manera que una multiplicidad de dichas pletinas se intersectan para definir unas líneas de intersección, caracterizado porque unos moldes dotados de cavidades se sitúan sobre dichas pletinas cerca de su intersección y en posición de alineación vertical con dicha línea de intersección, se coloca una cantidad predeterminada de material de soldadura fuerte en dichas cavidades de dichos moldes, se calientan conjuntamente dicha reja y dichos moldes hasta que dicho material de soldadura fuerte se funda y fluya hacia abajo por gravedad a lo largo de dichas líneas de intersección, poniendo así en contacto las pletinas adyacentes y llenando los espacios entre dichas pletinas, y se enfrían dicha reja y dichos moldes solidificando así dicho material de soldadura fuerte y estableciendo de este modo una unión soldada permanente a lo largo de dicha línea de intersección para unir permanentemente dichas pletinas.
