PROBLEM TO BE SOLVED: To provide a lap fillet arc-welding joint excellent in fatigue strength when two plates are lap fillet-welded by an arc-welding.SOLUTION: A lap fillet arc-welding joint 1 is prepared by overlapping two plates and by welding the end part of one plate (a vertical wall part 9a of an upper side part 9) and the surface of the other plate (a vertical wall part 3a of a lower side part 3) along the end part of said one plate. The lap fillet arc-welding joint is characterized in that a protruding bead-shaped bent salient 5 protrudes to the surface side of the vertical wall part 3a, and in that a weld stopping end 1a is positioned at the peak portion of the protruding bead-shaped bent salient 5.SELECTED DRAWING: Figure 1 |
