摘要： The disclosed technology generally relates to consumable electrode wires and more particularly to consumable electrode wires having a core-shell structure, where the core comprises chromium. In one aspect, a welding wire comprises a sheath having a steel composition and a core surrounded by the sheath. The core comprises chromium (Cr) at a concentration between about 12 weight % and about 18 weight % on the basis of the total weight of the welding wire, manganese (Mn) at a concentration between about 12 weight % and about 18 weight % on the basis of the total weight of the welding wire, nickel (Ni) at a concentration between zero and about 5 weight % on the basis of the total weight of the welding wire, and carbon (C) at a concentration greater than zero weight %, wherein concentrations of Ni, C and Mn are such that [Ni]+30[C]+0.5[Mn] is less than about 12 weight %, wherein [Ni], [C], and [Mn] represent weight percentages of respective elements on the basis of the total weight of the welding wire. The disclosed technology also relates to welding methods and systems adapted for using the chromium-comprising electrode wires.
