PROBLEM TO BE SOLVED: To provide a fillet welding method that enables a superior bead to be obtained even at an increased welding speed. SOLUTION: In a horizontal fillet welding method with two electrodes, a preceding electrode 2 and a succeeding electrode 3, using a flux cored wire 1, the welding current of the succeeding electrode 3 is designed to be in the range of 0.8-0.9 times as much as that of the preceding electrode; the distance L between the two electrodes 2, 3 is made within the range of 10-100mm; the push angleθ1 of the preceding electrode 2 and the dray angleθ2 of the succeeding electrode 3 are each made within the range of 5 deg.-100 deg.; with this method, a stable molten pool is formed without molten outflow, enabling a defect-free bead to be obtained.
