Abstract

Dispositif pour régulariser en hauteur, par martelage, le cordon de soudure de tubes soudés longitudinalement comportant à l'intérieur du tube une enclume montée à l'extrémité d'une barre traversant le tube, réglable en position longitudinale, venant au contact par sa surface extérieure contre la paroi interne du tube, une masse extérieure de martelage animée d'un mouvement vertical alternatif, et un élément d'appui monté à l'opposé de la masse de martelage. Il est caracterisé par le fait que la masse de martelage est mue de façon à présenter une cadence de frappe supérieure à 2 500 coups/minute, et que l'enclume comporte axialement de part et d'autre un embout en élastomère. Application à la fabrication de tubes métalliques, notamment en acier.
