PURPOSE: An agglomerated flux for submerged arc welding is provided to have weldability without consuming excess flux over various welding methods. CONSTITUTION: The agglomerated flux for submerged arc welding is characterized by constituting SiO2 11-33wt.%, Al2O3 12-42wt.%, TiO2 15-45wt.%, CaO 0.5-7wt.%, CaF2 0.5-5wt.%, MgO 1-10wt.%, 0.05-5wt.% of one or more constituents selected from Na2O, K2O and Li2O, Fe 1-10wt.% and 2-10wt.% of CO2, which is calculated in terms of carbonates.
