  • Patent number: 10427250
    Abstract: 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.
