Title:
DIFFERENT MATERIAL PANEL STRUCTURE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2013184198
Kind Code:
A
Abstract:
To provide a practical method capable of suppressing the generation of the hem gap and warpage in the outer panel made of an aluminum alloy on coating/baking of an automobile body in the hemming parts of the corner parts in a different material panel structure.
In the corner parts of a panel structure obtained by integrating an outer panel 1 made of an aluminum alloy and an inner panel 2 made of steel by hemming parts 21, the hemming parts 21 only in the corner parts having long length and on which loads on outer panel thermal expansion are acted are welded and joined to a spotlike manner and are bound to suppress the generation of the hem gap and warpage in the outer panel 1.
