Abstract

See full text

The present disclosure relates generally to welding alloys and, more specifically, to welding consumables (e.g., welding wires and rods) for arc welding operations. In an embodiment, a welding consumable 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. The welding consumable also includes one or more grain control agents selected from the group: niobium, tantalum, titanium, zirconium, and boron, wherein the welding consumable includes less than approximately 0.6 wt % grain control agents. Additionally, the welding consumable has a carbon equivalence (CE) value that is less than approximately 0.23. The welding consumable is designed to provide a manganese fume generation rate that is less than approximately 0.01 grams per minute during a welding operation.
