The disclosure relates to a process for producing girders in the shape of flanged sections, in particular T- or I-beams, in which at least one edge of the web is welded to the broad surface of at least one flange, wherein the improvement resides in that at least one flange is bent up on both sides of the predetermined welding seam line against the contraction angle to be expected during welding, by an angle which is greater than this contraction angle, and the flanges of the formed beam are bent back after welding into the desired position. This process has the advantage that one is independent from deformations in the welding machine, and that contraction stresses are eliminated. |
