The invention relates to a welding material, in particular to an improved welding material which improves surfacing electrodes or flux-cored wires and resists the corrosion of liquid zinc and aluminium-zinc-based alloy. According to the portions by weight, the electrode coating or flux-cored wire of the welding material comprises the components as follows: 0.1-8 portions of graphite, 1-8 portionsof rutile, 8-25 portions of marble, 9-30 portions of fluorite, 5-16 portions of feldspar, 1-5 portions of mica, 0.1-25 portions of chrome powders, 10-40 portions of ferrosilicon, 10-15 portions of ferromanganese, 10-20 portions of molybdenum powder, 0.1-15 portions of aluminium powder, 0.1-25 portions of nickel powder, 1-10 portions of titanium dioxide, 5-20 portions of ferrotitanium, 0.1-5 portions of rare earth, 0.1-15 portions of ferrotungsten, and 1-10 portions of ferroboron. By adopting the proposal of the invention, the usage temperature of the welding material is ranged from 480 to 550DEG C; furthermore, the welding material of the invention effectively improves the anti-corrosion of zinc and the improved anti-corrosion of liquid zinc and aluminium-zinc-based alloy.
