SYSTEMS AND METHODS FOR LOW-MANGANESE WELDING ALLOYS

摘要

The present disclosure relates generally to welding alloys and, more specifically, to welding consumables (e.g., welding wires and rods) for welding, such as Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW), and Flux Core Arc Welding (FCAW). In an embodiment, a welding alloy includes less than approximately 1 wt % manganese as well as one or more strengthening agents selected from the group: nickel, cobalt, copper, carbon, molybdenum, chromium, vanadium, silicon, and boron. Additionally, the welding alloy has a carbon equivalence (CE) value that is less than approximately 0.23, according to the Ito and Bessyo carbon equivalence equation. The welding alloy also includes one or more grain control agents selected from the group: niobium, tantalum, titanium, zirconium, and boron, wherein the welding alloy includes less than approximately 0.6 wt % grain control agents.
