Abstract
A flux-contained welding wire is provided wherein a conductive core wire can be disposed without any complicate manufacturing steps performed on a metal outer layer. Flux is filled inside of the metal outer layer. The conductive core wire is disposed nearly in the center of the flux without being supported by the metal outer layer. The flux contains 20-80 weight % of metal powder. A weight % of the weight of the flux to the weight of the welding wire per unit length is set in a range of 6.5-30 weight %. The weight % of the weight of the conductive core wire to the weight of the welding wire per unit length is set in a range of 1.5-15 weight %.
