PROBLEM TO BE SOLVED: To provide a prevention method of a crack caused when a welding bead approaches, in the case of welding of a stiffener.SOLUTION: A method is provided for fillet-welding a stiffener and a plate, by arranging one stiffener by crossing on the plate via a scallop of the other stiffener. In a fillet-welding method of the stiffener, an interval La between a scallop end part of the stiffener having the scallop and the stiffener arranged via the scallop is set in less than 50 mm, and among a fillet-welding part of the stiffener having the scallop, the fillet-welding part existing between the stiffener arranged via the scallop and a position separated by 50 mm or more from the stiffener arranged via the scallop, is formed as a first fillet-welding part, and a fillet-welding part except for the first fillet-welding part is formed as a second fillet-welding part, and the second fillet-welding part is fillet-welded in the first place, and the first fillet-welding part is fillet-welded thereafter.SELECTED DRAWING: Figure 5 |
