摘要： 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.

摘要： This disclosure relates generally to welding and, more specifically, to electrodes for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW) of zinc-coated workpieces. In an embodiment, a welding consumable for welding a zinc-coated steel workpiece includes a zinc (Zn) content between approximately 0.01 wt % and approximately 4 wt %, based on the weight of the welding consumable. It is presently recognized that intentionally including Zn in welding wires for welding galvanized workpieces unexpectedly and counterintuitively alleviates spatter and porosity problems that are caused by the Zn coating of the galvanized workpieces.
