SKELETON COMPONENT FOR AUTOMOBILE AND METHOD FOR MANUFACTURING SKELETON COMPONENT FOR AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To reduce deformation caused by thermal strain and improve dimensional accuracy while securing sufficient peeling strength.SOLUTION: In a skeleton component for an automobile, when as for a welded position coordinate is represented by such a coordination system that an end of a contact position between a flange portion and another frame component or a panel component is 0, a flange outer end side of the flange portion is represented by (-) and a vertical wall side in a substantial hat shape is represented by (+), a position X represented by relationship of -4t≤X≤-2t (t: plate thickness of frame component of substantial hat shape) is welded by one-sided welding.SELECTED DRAWING: Figure 1
