Structure for and the method of supporting an initial plurality of longitudinally extending large diameter reinforcing rods in transversely aligned spaced apart relation, separately feeding individual, transversely extending reinforcing rods onto the longitudinally extending reinforcing rods at a welding position, simultaneously welding the transversely extending reinforcing rod to each of the longitudinally extending reinforcing rods at the welding position, subsequently indexing the welded transversely extending reinforcing rod and longitudinally extending reinforcing rods a predetermined distance longitudinally of the longitudinally extending reinforcing rods, repeating the feeding, welding and indexing until transversely extending reinforcing rods are welded in predetermined parallel spaced apart relation over the length of the longitudinally extending reinforcing rods, and during the repetitive feeding, welding and indexing placing additional longitudinally spaced apart large diameter reinforcing rods on the initial longitudinally extending reinforcing rods axially displaced from the welding position, and moving the additional reinforcing rods into welding position after all required transverse reinforcing rods are welded to the initial longitudinally extending reinforcing rods, and repeating the method to continuously and automatically weld airport concrete mesh sections.
