Abstract

Perfeccionamientos en los moldes para soldadura, y más particularmente un molde en varias partes destinado a la soldadura metalotérmica de dos pieza metálicas, que deja alrededor de los extremos de las piezas a soldar una cavidad de colada destinada a recibir una cierta cantidad de fluido de soldadura caliente, caracterizados porque una por lo menos de las superficies del molde, destinada a entrar en contacto con una pieza a soldar o eventualmente con otra parte del molde, comprende un resalte que presenta un flanco inclinado hacia el exterior con respecto a la cavidad de colada, estando dicho resalte revestido con una junta de estanquidad constituida por una cinta de un material compresible de baja pérdida al fuego una de cuyas caras está pegada sobre dicho resalte.
