The invention belongs to the technical field of welding materials, and particularly relates to a plunger repairing surfacing flux-cored wire suitable for sintered welding flux. The plunger repairing surfacing flux-cored wire is composed of a steel belt and powder. An SPCC cold-rolled carbon steel belt is adopted as the steel belt, and the filling rate of the powder is 35%-40%. The powder comprisescomponents including, by mass percent, 10%-15% of high carbon ferro chrome, 10%-15% of high carbon ferromanganese, 55%-60% of micro-carbon ferro chrome, 1%-3% of rare earth silicon and 0.5%-1% of aluminum oxide and 8%-15% of one or more of ferrovanadium, ferrotungsten, ferromolybdenum and nickel powder. 本发明属于焊接材料技术领域，特别涉及种适用于烧结型焊剂的柱塞修复用堆焊药芯焊丝，由钢带和药粉组成，钢带采用SPCC冷轧碳钢钢带，药粉的填充率为35-40%；所述药粉中各组分的质量百分比为：高碳铬铁10-15%，高碳锰铁10-15%，微碳铬铁55-60%，稀土硅1-3%，氧化铝0.5-1%，钒铁、钨铁、钼铁、镍粉中种或几种8-15%。
