号）2. Description of the Related Art In a railcar structure using a honeycomb panel having a pair of face plates and a core arranged between the face plates, and the face plates and the core being joined to each other, damage to the honeycomb panel is caused by pebbles jumping up during traveling. May occur. As a repair method in such a case, a hole penetrating the pair of face plates of the damaged portion is provided and a member to be repaired is inserted into the hole. Then, it is known to weld the repair member and the respective face plate. In this case, the repair member has a large diameter flange and a small diameter flange, and the small diameter flange is inserted into the hole. At this time, the large-diameter flange overlaps the face plate of the repaired honeycomb panel in the opening, while the small-diameter flange overlaps the other face plate.

There is. Therefore, in order to make the surface of the repaired portion smooth, it was necessary to weld the small-diameter flange portion by overlay welding. As a result, there is a problem in that the amount of welding in the overlay welded portion increases and the welding strain in the repaired portion increases.
