IPC: B61D17/00
Filed: 2002-07-12
Abstract: <P>PROBLEM TO BE SOLVED: To obtain the smoothing in friction stir welding and plane welded faces with flat surfaces when double skin panels used for producing a wide panel body are subjected to friction stir welding to each other by using a bobbin tool.  <P>SOLUTION: The free ends of panels are composed so that ribs are not present insides. As for the double skin panels 30A and 30B to be welded, in the thickness of face plates 31 and 32 on the sides of the free ends, compared with the thickness of the face plates in hollow parts located on the sides inner than the free ends 33A and 33B via the ribs of the panels, the thickness of the face plates in the other free ends is set so as to be made higher; and the height between the face plates in the double skin panels is set so that the face plates on the sides of the free ends are welded to each other. In the butt or engagement parts, friction stir welding is performed by a bobbin tool 10 with which friction heat is inputted from shoulder faces to both the surface and back faces so that the pressing force against the back face side is higher than that against the surface side.  <P>COPYRIGHT: (C)2004,JPO
