Title (EN) FORGE WELDING METHOD
(FR) PROCEDE DE SOUDAGE PAR FORGEAGE
Abstract: front page image
(EN)A method for forge welding tubulars such that formation of upsets in the welding zone is minimized comprises shaping the tubular ends that are to be welded together into an inwardly sloping configuration such that when the tubular ends are heated during the forge welding process the heated tubular ends deform as a result of thermal expansion into a substantially longitudinally oriented cylindrical shape.
(FR)L'invention concerne un procédé de soudage par forgeage de matériaux tubulaires, qui permet de réduire au minimum la formation de refoulements dans la zone de soudure. Le procédé consiste à former les extrémités tubulaires devant être soudées ensembles en une configuration inclinée vers l'intérieur, de sorte que lorsque les extrémités tubulairessont chauffées pendant l'opération de soudage à la forge, elles se déforment du fait de la dilatation thermique et prennent une forme cylindrique sensiblement longitudinale.
