Abstract
A flux-cored wire for laser welding or MIG welding different materials, wherein the different materials are aluminum or an aluminum alloy material and a galvanized steel material. The flux-cored wire contains a cylindrical aluminum alloy sheath containing: aluminum, 0.8-1.9 mass % Si, at most 0.1 mass % Mn, 0.1 mass % Mg, and 0.1 mass % Fe; and a flux filled in a space within the sheath and containing 20-60 mass % cesium fluoride, wherein the percentage filling of the flux is 5-20 mass % with respect to the total mass of the flux-core wire.
