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.

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

A tailor-welded blank is made of two steels, one steel of Alloy A and one steel of Alloy B. Alloy A comprises 0.10-0.50 wt % C, 0.1-0.5 wt % Si, 2.0-8.0 wt % Mn, 0.0-6.0 wt % Cr, 0.0-2.0 wt % Mo, 0.0-0.15 wt % Ti, and 0.0-0.005 wt % B and wherein Alloy B comprises 0.06-0.12 wt % C, 0.1-0.25 wt % Si, 1.65-2.42 wt % Mn, 0.0-0.70 wt % Cr, 0.08-0.40 wt % Mo, 0.0-0.05 wt % V, and 0.01-0.05 wt % Ti.
