Zusammenfassung:	The invention is directed to increasing the quality of the processing and preparation of end faces for welding. A device for preparing end faces of preferably flexible thin-walled semi-finished casings for welding comprises a body in the form of a circular horizontal support plate with an annular separator arranged thereon, which support plate is equipped with deforming elements, wherein, alternately, sectors with a group of deforming elements with a longitudinal axis which is directed along the radius of the support plate and sectors with a group of deforming elements with a longitudinal axis which is directed at an angle of a° with respect to the radius of the support plate are formed in the separator along the annular zone, wherein the ratio of the quantity of elements in the first group to the quantity of elements in the second group is (3-6):1, and the angle a° is accordingly in the range of 35-50°. La présente invention vise à améliorer la qualité du traitement et de la préparation à la soudure d'extrémités et concerne en particulier un dispositif de préparation à la soudure d'extrémités de tubes semi-finis à parois minces de préférence flexibles, lequel dispositif comprend un corps se présentant sous la forme d'une plaque d'appui horizontale circulaire sur laquelle est disposé un séparateur annulaire et comportant des éléments de déformation. Des zones comprenant tantôt un groupe d'éléments de déformation dont l'axe longitudinal est orienté le long du rayon de la plaque d'appui, tantôt un groupe d'éléments de déformation dont l'axe longitudinal est orienté selon un angle de a° par rapport au rayon de la plaque d'appui sont successivement formées dans le séparateur le long de la zone annulaire, le rapport quantité d'éléments contenus dans le premier groupe sur quantité d'éléments contenus dans le second groupe étant de (3-6):1, l'angle a° étant, selon les cas, compris entre 35 et 50°.
