Abstract

L'invention concerne le soudage des métaux par résistance. La machine de soudage faisant l'objet de l'invention est caractérisée notamment en ce que le systeme de commande des thyristors 3, 4 est réalisé d'apres le principe de l'autocxcitation et qu'il comporte un sous-ensemble 8 de détection du début et de la fin des impulsions de courant primaire, la sortie de ce dispositif de détection étant connectée à une partie des entrées d'éléments 11 de multiplication logique des signaux, les autres entrées desquels sont raccordées à un régulateur 12 de la durée des intervalles de temps constituant l'impulsion de courant de soudage. L'invention s'applique notamment au soudage par résistance des alliages légers et des alliages de titane.
