Abstract

A beam article for a vehicle includes a plurality of separate elongated metal sheets attached together to form generally planar walls of an elongated tubular structure. At least one of the plurality of separate elongated metal sheets has a shear wall that is disposed along a hollow interior of the elongated tubular structure and is attached at opposing walls of the elongated tubular structure. At least one of the plurality of separate elongated metal sheets comprises an edge that abuts a side surface of an adjacent one of the plurality of separate elongated metal sheets to define a non-radiused perpendicular weld corner along the elongated tubular structure.

First claim

The invention claimed is:

1. A beam article for a vehicle, said beam article comprising:
a plurality of separate elongated metal sheets attached together to form generally planar walls of an elongated tubular structure;
wherein at least one of the plurality of separate elongated metal sheets comprises a shear wall that is disposed along a hollow interior of the elongated tubular structure and is attached at opposing walls of the elongated tubular structure; and
wherein at least one of the plurality of separate elongated metal sheets comprises an edge that abuts a side surface of an adjacent one of the plurality of separate elongated metal sheets to define a non-radiused perpendicular weld corner along the elongated tubular structure.

2. The beam article of claim 1 , wherein at least one of the plurality of separate elongated metal sheets comprises a generally vertical wall of the tubular structure.

3. The beam article of claim 1 , wherein at least one of the plurality of separate elongated metal sheets comprises a generally horizontal wall of the tubular structure.

4. The beam article of claim 1 , wherein the elongated tubular structure comprises a non-linear shape in a generally horizontal plane along a length of the tubular structure.

5. The beam article of claim 1 , wherein at least two of the plurality of separate elongated metal sheets are arranged horizontally and comprise a non-linear edge that attaches along a side surface of a generally vertical wall of the tubular structure to provide a non-constant width between vertical walls of the tubular structure.

6. The beam article of claim 5 , wherein the shear wall is disposed in a generally horizontal orientation.

7. The beam article of claim 1 , wherein the shear wall attaches at generally vertical walls of the tubular structure formed by two of the plurality of separate elongated metal sheets.

8. The beam article of claim 7 , wherein an upper sheet of the plurality of separate elongated metal sheets comprises an upper horizontal wall of the tubular structure that is recessed below an upper edge of the vertical walls to provide a channel at an upper surface the tubular structure.

9. The beam article of claim 1 , wherein the tubular structure has a non-consistent cross section along the length of the tubular structure.

10. A beam article for a vehicle, said beam article comprising:
a plurality of separate metal sheets each having a planar shape and attached together to form an elongated tubular structure enclosing a hollow interior area; and
wherein at least two of the plurality of separate metal sheets are arranged horizontally and comprise a non-linear edge that attaches along a side surface of a generally vertical wall of the elongated tubular structure to define a non-radiused corner of a cross section taken transversely to a length of the elongated tubular structure and to provide a non-constant width along the elongated tubular structure.

11. The beam article of claim 10 , wherein at least one of the plurality of separate metal sheets comprises a shear wall that is disposed along the hollow interior area of the elongated tubular structure and is attached at inside surfaces of opposing vertical walls of the elongated tubular structure.

12. The beam article of claim 11 , wherein the shear wall is disposed in a generally horizontal orientation.

13. The beam article of claim 10 , wherein the elongated tubular structure comprises a non-linear shape in a generally horizontal plane along a length of the tubular structure.

14. The beam article of claim 10 , wherein an upper sheet of the plurality of separate metal sheets comprises an upper horizontal wall of the elongated tubular structure that is recessed below an upper edge of opposing vertical walls of the elongated tubular structure to provide a channel at an upper surface the elongated tubular structure.

15. The beam article of claim 10 , wherein the tubular structure has a non-consistent cross section along the length of the tubular structure.

16. The beam article of claim 10 , wherein the plurality of separate metal sheets are attached together via welding with a weld material that is annealed in a localized region of the elongated tubular structure.

17. The beam article of claim 10 , wherein at least one of the plurality of separate metal sheets does not extend a length of the elongated tubular structure.

18. A beam article for a vehicle, said beam article comprising:
a plurality of separate pre-formed sheets attached together to form generally planar walls of an elongated tubular structure;
wherein at least two of the plurality of pre-formed sheets comprise vertical walls;
wherein at least three of the plurality of pre-formed sheets comprise horizontal walls; and
wherein the horizontal walls each comprise opposing edges edge that attach at inside surfaces of the vertical walls to each define a non-radiused perpendicular weld corner.

19. The beam article of claim 18 , wherein the elongated tubular structure comprises a non-linear shape in a generally horizontal plane along a length of the elongated tubular structure.

20. The beam article of claim 19 , wherein the horizontal walls each comprise a non-linear edge that attaches along a side surface of one of the vertical walls to provide a non-constant width between the vertical walls of the tubular structure.
