Zusammenfassung:	Method for screwing a threaded joint for steel pipes, intended particularly to the oil industry, of the type comprising a male element (1) with an outer threading (3) and a female element (2) with an inner threading (4), as well as at least one pair of stops (5, 6) for limiting the screwing and provided inside the female element (2). Before proceding to the screwing of the joint, a strain gauge is applied to the outer surface of the female element (2) at a certain distance from the plane of the screwing limitation stop and on the side of said plane opposite to the threadings (3, 4), which strain gauge enables to follow instantaneously the longitudinal deformation of the outer surface according to a generatrix of the female element (2), and the screwing of the joint is effected until the indication provided by the strain gauge corresponds to an extension of the predetermined value of the surface of the female element (2) according to said generatrix at the level of the gauge. Procédé pour réaliser le vissage d'un joint fileté pour tubes d'acier, destiné en particulier à l'industrie du pétrole, du type comportant un élément mâle (1) à filetage externe (3) et un élément femelle (2) à filetage interne (4), ainsi qu'au moins un couple de butées (5, 6) de limitation de vissage situées à l'intérieur de l'élément femelle (2). Avant de procéder au vissage du joint, on applique sur la surface externe de l'élément femelle (2) à une certaine distance du plan de la butée de limitation de vissage et du côté dudit plant qui est opposé aux filetages (3, 4), une jauge de contraintes qui permet de suivre instantanément les déformations longitudinales de la surface externe selon une génératrice de l'élément femelle (2), et on effectue le vissage du joint jusqu'à ce que l'indication fournie par la jauge de contraintes corresponde à une extension d'une valeur prédéterminée de la surface de l'élément femelle (2) selon ladite génératrice au niveau de la jauge.
