1. A cable welding wire, comprising: a central welding wire and n peripheral welding wires spirally winding around the central welding wire, with each of the peripheral welding wires having a diameter of dperipheral, and adjacent peripheral welding wires being arranged to be tangential to each other, wherein, the peripheral welding wire has a lay length T, which satisfies the equation of T=m×(dperipheral+dcentral)/2, where m is a multiple of the lay length, dperipheral is a diameter of the peripheral welding wire, dcentral is a diameter of the central welding wire, and 3.2≤m<20,
an included angle between a rotation direction of the peripheral welding wire and a direction perpendicular to a length of the central welding wire or between a normal plane of the peripheral welding wire and a plane where the central welding wire is located is a helix angle α, wherein, 26.99°≤α<72.56°,
wherein,
when a thickness of a surfacing layer is required to be less than 3 mm, m≤9, α≤55.08°, so that the penetration depth during surfacing welding of the cable welding wire can be controlled to be no more than 1 mm;
when the thickness of a surfacing layer is required to be 3 mm to 6 mm, m≤14, α≤65.83°, so that the penetration depth during surfacing welding of the cable welding wire can be controlled to be no more than 2 mm; and
when the thickness of a surfacing laver is required to be more than 6 mm, m<20, α<72.56°, so that the penetration depth during surfacing welding of the cable welding wire can be controlled to be no more than 3 mm.
