Correlation between Arc Phenomena and Welding Parameters in Submerged-Arc Welding

Journal of the Japan Welding Society, 1981
In submerged arc welding, the direction of arc column and the position of molten metal in the crater have been examined using a X-ray image intensifier TV system in order to regulate weld bead shape by controlling welding parameters.Arcs are classified into the open and buried arcs depending on the position of electrode tip to the plate surface.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.
