  • SHIELDING AND COOLING A CONTINUOUS WELD BETWEEN STEEL SHEETS/PLATES USING A NON-OXIDIZING ATMOSPHERE TO REDUCE THE FORMATION OF OXIDE ON A SURFACE OF THE CONTINUOUS WELD
    Publication number: 20200316726
    Abstract: An apparatus for use in a continuous welding system including a welding head configured to remain stationary relative to translating steel sheets or plates. The apparatus includes a hollow elongate body and a port. The body extends between two closed ends. The port is coupled to a non-oxidizing gas source and in communication with the body. The body defines a plurality of openings. The openings are configured to direct non-oxidizing gas towards the steel sheets or plates to simultaneously shield a weld formed by the welding head from atmosphere and cool the weld.
