Abstract: The bumper stay includes a cylindrical shaft member fit in to a hole of a bumper reinforce, a cylindrical reinforcing member fit in to the outer periphery of the shaft member in the rear side of the bumper reinforce, and a mounting flange member fit in to the outer periphery of the shaft member in its rear end. The shaft member is enlarged by electromagnetic forming and is tightly adhered to the inner peripheral surface of the hole formed in the bumper reinforce, the inner peripheral surface of the reinforcing member, and the inner peripheral surface of the hole flange formed in the mounting flange member, thereby these are joined with each other. Thin aluminum alloy extruded material can be used for the shaft member. With such configuration, when a bumper stay is fit in to the holes formed in the front and rear walls of the bumper reinforce and the bumper stay is enlarged by electromagnetic forming to join with the bumper reinforce, joining of the both can be firmly performed and sufficient strength and energy absorption quantity can be secured.

Abstract: A lightweight car body energy absorber made of Al alloy which provides a high energy absorption performance. The car body energy absorber comprises a hollow shape with a rectangular sectional profile and a reinforcing shape attached to the front face of the collision plane of the hollow shape, where the hollow shape and the reinforcing shape are aluminum alloy extruded shapes. The reinforcing shape has a hat-shaped open sectional profile, which is composed of a collision wall almost parallel to the collision plane of the hollow shape, plural mutually parallel horizontal ribs which support the collision wall, and vertical flanges provided at the tips of these ribs. The reinforcing shape is joined to the collision plane of the hollow shape through the vertical flanges.

Abstract: Sections 1 and 2 each in the form of a welded pipe (square pipe) are provided. The sections 1 and 2 are brought into abutment with each other so that the respective end faces 3a and 3b abut each other at a predetermined angle .beta. between each section and its axial direction. The sections 1 and 2 are arranged symmetrically with respect to each other. Acute end portions of the abutted portion are chamfered to from a plane part. Corners of the sections 1 and 2 are rounded. In such a combined state of both sections, the abutted portion is welded in the circumferential direction to form a weld bead. As a result, penetration of weld metal to the section 1 and that to the section 2 become equal to each other. Thus, it becomes possible to fabricate a welded structure having a uniform weld bead and having improved strength and reliability of welded portions.
