Lid box joining structure and joining method

摘要

In a joining structure of a lid box according to an embodiment of the invention, a joining area where a joining surface of a joining portion of a side outer panel faces a joining surface of a joining portion of the lid box includes a first area where the joining surfaces come into contact with each other and are supposed to be subjected to spot-welding and a second area where the joining surfaces are separated from each other by a predetermined gap and are supposed to be subjected to laser-welding, and the spot-welding is performed on the first area or the laser-welding is performed on the second area. For that reason, since the joining states respectively suitable for the spot-welding and the laser-welding are realized, sufficient welding quality is ensured in both the spot-welding and the laser-welding.

主权项

1. A lid box joining structure that joins a lid box to a side outer panel of a vehicle body,
wherein a joining area where a joining surface of the side outer panel faces a joining surface of the lid box includes a first area where the joining surface of the side outer panel and the joining surface of the lid box come into contact with each other and are supposed to be subjected to spot-welding and a second area where the joining surface of the side outer panel and the joining surface of the lid box are separated from each other by a predetermined gap and are supposed to be subjected to laser-welding, and wherein the spot-welding is performed in the first area or the laser-welding is performed in the second area.
