Abstract
Método para soldar tubos de acero inoxidable austenítico los unos con los otros sin aumentar sustancialmente la tendencia a la formación de fisuración por tensocorrosión del conjunto de tubería resultante, caracterizado porque incluye las operaciones que consisten en situar en cada extremidad de cada tramo de tubo una pieza en forma de manguito separada que tiene una porción de extremidad libre de sección transversal radial sustancialmente más importante y una superficie generalmente seudocónica y que tiene otra porción de extremidad sujeta en la prolongación del tramo de tubo, en situar dos subconjuntos de este tipo con las porciones de extremidad libre de sus piezas en forma de manguito enfrentadas para definir una cavidad anular entre los subconjuntos, y en soldar conjuntamente los dos subconjuntos llenando sustancialmente la cavidad anular con metal de soldadura.
