Abstract
A cable-type welding wire provided in the present application, includes a central welding wire and n peripheral welding wires arranged so as to be spirally wound on 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 wires have a lay length of 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. This application can obtain a smaller penetration depth when the welding parameters remain constant due to a small multiple of the lay length of the cable-type welding wire, and can further reduce welding arcing current.
