Abstract

La présente invention concerne un moule en plusieurs parties destine à la soudure métallothermique de deux pièces métalliques en ménageant autour des abouts à souder une cavité de coulée destinée à recevoir une certaine quantité de fluide de soudure chaud. Ce moule est caractérisé par le fait que les parties de moule comportent dans leurs portions en contact entre elles au-dessus de la cavité de coulée des surfaces emboîtables assurant le positionnement et l'étanchéité de ces portions entre elles, ainsi que la création d'un évent pour l'évacuation de l'air au moment de la coulée. Application notamment à la soudure de rails de chemin de fer.
