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.
