Disclosed is a flux cored wire for gas shielded arc welding, which is capable of offering excellent workability and providing a weld metal with an improved impact value at low temperature. The flux cored wire for gas shielded arc welding is characterized in that a titania-based flux composition is filled into a sheath for mild steels of low-carbon steels, and the flux composition contains 4.0 to 8.0% TiO , 1.0 to 3.0% Mn, 0.1 to 1.0% Si, 0.002 to 0.02% B, 0.2 to 0.45% Mg and 0.15 to 0.3% Al, by weight relative to the total weight of the wire.
