Title:
HOLLOW STRUCTURAL ANGLE FOR FRICTION STIR JUNCTION
Document Type and Number:
Japanese Patent JP3459206
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To join hollow structural angles suitably from one side regardless of measurement accuracy of the hollow materials or the like.
SOLUTION: Projecting pieces 12b and 22b of face plates of hollow structural angles 10 and 20 are joined by friction stir from upside. Then, a connection material 30 is put on seats for friction stir junction from upside. The seats are placed on an intersection of the face plate 21 and a rib joining the two face plates 21 and 22. The junction between the connection material 30 and the seats are lap junction and not butt junction. This facilitates the junction, even if the hollow structural angles 10 and 20 have errors of manufacture and arrangement.
