Abstract

L'invention concerne un procédé de soudure des extrémités de deux éléments tubulaires, procédé selon lequel les éléments à souder entre eux sont immobilisés lors de l'opération de soudure et l'organe de soudage est déplacé autour desdits éléments. Le procédé selon l'invention se caractérise par le fait : - qu'après mise bout à bout des éléments à assembler, on effectue une première passe de soudure sans apport de métal ; - que l'on provoque une dépression à l'intérieur des éléments ainsi réunis ; - et enfin, que l'on réalise au moins une seconde passe de soudure en maintenant cette dépression. Application : soudure bout à bout de tubes ou similaires.
