Abstract

L'invention concerne le soudage. La machine à souder faisant l'objet de l'invention est du type comprenant une mâchoire mobile et une mâchoire fixe pour le serrage des pièces à souder, avec des actionneurs hydrauliques et des distributeurs pour la commande individuelle de ces actionneurs, et est caractérisée notamment en ce qu'elle comporte une centrale hydraulique autonome à accumulateur supplémentaire comportant une soupape de sûreté 19 et un clapet de non-retour 20 et reliée hydrauliquement au vérin hydraulique 11 du mécanisme de déplacement de la mâchoire mobile. L'invention s'applique notamment au soudage de pièces de grande section.
