Surfacing welding wire for wearing plate

The invention provides a surfacing welding wire for a wearing plate. The surfacing welding wire for the wearing plate comprises a welding wire main body, an outer skin part is provided outside the welding wire main body, and the outer skin part is filled with powder; the weight of the outer skin part accounts for 40-60%, the mass percentage of each component of the powder opposite to the welding wire main body is as follows: 2.0-3.5% of high carbon ferromanganese, 1.8-3.0% of boron carbide, 2.2-3.2% of graphite, 1.1-1.4% of silicon carbide, 45-55% of high-carbon ferrochrome, 0.35-0.6% of sodium fluoroaluminate, 0.35-0.6% of aluminum powder, 0-0.5% of magnesium powder, 0-9% of ferromolybdenum, 0-3% of ferrovanadium, 0-6% of ferrotungsten, 0-9% of ferroniobium, 0-0.5% of rare earth silicon and 0.15-0.25% of arc stabilizer. Through adding high-carbon ferromanganese and other components in the powder, the surfacing welding wire for the wearing plate can be formed well and the toughness isstrong. 本发明提供了一种耐磨板堆焊焊丝，包
