[0018] Example 1
[0019] A stranded welding wire for high-strength steel comprises a flux core and an outer skin covered on the outside of the flux core, and the weight ratio of the flux core to the skin is 2.5:10; the flux core comprises by weight percentage: graphite powder 4%, nano-titanium dioxide 0.2% , rutile 20%, calcium oxide 2%, tungsten powder 3%, metal chromium 0.8%, sodium fluoride 4.2%, lithium fluoride 0.12%, yttrium trioxide 0.4%, metal manganese 1%, potassium titanate 2%, Nickel powder is 4%, Ti-Nb-V-Fe alloy is 2%, and the balance is iron powder.
[0020] Among them, in the Ti-Nb-V-Fe alloy, titanium element accounts for 2% by mass, niobium element accounts for 18% by mass, and vanadium element accounts for 8% by mass.
[0021] The above-mentioned preparation process of stranded welding wire for high-strength steel includes rolling the outer skin into a U-shaped groove, placing the flux core in the U-shaped groove, and extruding and rolling into an O-shaped ...
