Abstract

Procedimiento para soldar elementos de armadura de una reja de conjunto de combustible de reactor nuclear en el cual se ensamblan unas tiras provistas de concavidades y de muelles para formar la reja, se disponen unos elementos de armadura periféricamente alrededor de dicha reja de modo que las extremidades de los elementos adyacentes se superpongan mutuamente, y se sitúan con dicha reja en una plantilla dotada de zonas de esquina abiertas.
