Abstract: PURPOSE:To prevent the deterioration of a wire quality by filling a bend-formed metallic tube with flux, etc. as well as truing up the butt-joined parts of the tubes to the outside of a reel. CONSTITUTION:A metallic tube 2 is formed by bending a long-sized metallic strip in its width direction, and its inside is filled with powder 3 consisting of flux and metallic powder, to form a flux-cored welding wire 1. The wire 1 is reeled and shipped, but when reeling; the wire 1 is properly twisted so that the butt-joined parts 4 of wires 1 are trued up to the outside. The direction of the joined part 4 is regulated preferably to the degree of the range of + or -45 deg. with respect to the diametral direction of reel 6. In this way, the adsorption of moisture, etc. of the wire 1 during its storage, is remarkably reduced. Accordingly, the deterioration of wire 1 quality is prevented.
