Title:
HOLLOW SHAPE MATERIAL
Document Type and Number:
Japanese Patent JP3224091
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain a satisfactory welding in performing friction welding.
SOLUTION: In the butted part of the hollow shape 31 and 32, projecting parts 37a and 38a projecting outside the shape, are provided. By inserting a rotary body into these projecting parts 37a and 38a, the frictional welding is performed. Even if there is a gap in the butted part, it is buried by the metals of the projecting parts, and the satisfactory welding can be performed. After welding, by cutting the projecting parts 37a and 38a, the outside surfaces of the shape 31 and 32, can be made smooth. By positioning the rotary body on a prolonged line in the range of the plate thickness of a plate 36, the plate 36 becomes a supporting member, and the shape 31 and 32 can be prevented from being deformed.
