<p>Reinforcements elements are arranged in parallel side by side and in contact throughout their length. They withstand on their length a torsional effect and are comprised of sections (6) superposed and connected so as to transmit the forces. The connection is preferably a welding consisting at least of a welding bead. To form the welding bead two reinforcement elements spaced from each other are brought between two opposite welding electrodes with a welding wire. The wire is transformed by the welding current into a welding head (12), the reinforcement elements are pressed one against the other by the electrodes and fixed by the welding bead. </p> |
