Flux cored wire are formed on the substrate. One aspect of the present invention, in flux in flux cored wire which is filled with the metal shell, said fluxing hydrofoil % by weight with respect to a presence or absence to wire, BaF2 : 5. 0 - 14. 0%, rare earth oxide rare earth element in terms of amount : 0. 4 - 1. 5%, Mg based reducing agent and at least one selected from the group consisting Al based reducing agent and 1 : 2. 0 - 3. 8%, alkali metal fluoride : 0. 5 - 2. 4%, alkali metal carbonate : 0. 1 - 0. 35%, iron oxide : 2. 0 - 4. 0%, Mn : 1. 0 - 1. 2%, Ni + Zr : 0. 8 - 2. Comprising 2% flux cored wire is fixed to the body.
