There is provided a ring of sizing rollers the axes of which likewise lie at least approximately in the common plane. A guide roller is disposed adjacent another side of the rounded body blank diametrically opposite the one side engaged by the electrode rollers and offset forwardly in the direction of body blank movement with respect to the electrode rollers to guide the blank during welding of a longitudinal seam.
