The present invention relates to a flux cored wire having good brittle crack arrest performance, a method for manufacturing the same, and a welding joint produced by the same. According to the present invention, a flux cored wire with two or more fluxes filled in a metal strip, a method for manufacturing the same, and a welding joint produced by the same are provided. Therefore, since propagation of the crack in the welding portion is effectively suppressed, a welding structure capable of being safely protected from brittle crack is provided. |
