    • PROBLEM TO BE SOLVED: To provide a welding electrode in which the gas tracking property in a formed welding bead is degraded and the amount of diffusible hydrogen is reduced.
      SOLUTION: A cored electrode forms a weld bead with little or no gas tracking in a gas-shielded electric arc welding method. The cored electrode includes a metal sheath and a fill composition. The fill composition contains, by weight, a metal oxide slag forming agent of 15-80%, at least one fluorine containing compound of 0.5-20%, and a metal deoxidizing agent and/or a metal alloying agent of 1-70%, the percentage of the metal oxide slag forming agent is larger than that of the fluorine containing compound, and the fluorine containing compound brings at least 0.2% fluorine based on the percentage of the fill composition.
