The present invention relates to a welding material to regenerate an excavator, a crusher, and a roller used in a mining industry, a steel manufacturing industry, and other industries by overlay welding and, more specifically, relates to a flux-cored wire for gas-shield overlay welding having excellent weldability and abrasion resistance. The flux-cored wire for gas-shield overlay welding comprises: 0.3-0.7 wt% of carbon (C), 0.3-1.0 wt% of silicon (Si), 1.0-2.0 wt% of manganese (Mn), 4.0-8.0 wt% of chrome (Cr), 0.3-1.0 wt% of molybdenum (Mo), 1.0-2.0 wt% of LiF + Na_2CO_3, and the remainder consisting of iron (Fe) and other inevitable impurities. |
