PROBLEM TO BE SOLVED: To provide a flux cored wire for all position welding of a two-phase stainless steel by which arcs are stabilized, sputter development is suppressed and further excellent bead shapes and covering and the detachment of slag and the good welded metal characteristics are obtained in the all position weld ing of the two-phase stainless steel. SOLUTION: The flux cored wire for the all position welding of the two-phase stainless steel is filled with 18-26% flux in the outer shell of the stainless steel. The flux is composed by wt.% of 3.4-9.9% TiO2, 0.2-2.5% SiO2, 0.3-1.7% Al2O3, 0.11-0.5% metallic fluoride converted into F), 0.08-0.44% metallic Ti (converted into Ti) to the whole weight of the wire and the total amount of slag agent to the whole weight of the wire is 7.3-11.1%.
