Abstract

A blank for a vehicle door includes components arranged in the form of a blank for a front door or a rear door, each component including an edge that is adjacent to an edge of another one of the components, and welds produced by a laser, connecting the components along weld lines at the adjacent edges, each weld line of the blank for a front door being collinear with a corresponding weld line of the blank for a rear door.

Claims (25)

1. Vehicle door blanks, comprising:

first components arranged in the form of a first blank having a periphery for a front door, each component including an edge that abuts an edge of another one of the first components;

second components arranged in the form of a second blank having a periphery for a rear door, said periphery being different from the periphery for the front door, each second component including an edge that abuts an edge of another one of the second components; and

welds interconnecting the first components along weld lines at the respective abutting edges and interconnecting the second components along weld lines at the respective abutting edges, each weld line of the first blank being collinear with a corresponding weld line of the second blank.

2. The blanks of claim 1 wherein the components are of sheet metal.

3. The blanks of claim 1 wherein the each welded blank is in one-piece.

4. The blanks of claim 1 wherein the welds are substantially continuous along each weld line and extend through a thickness of the components.

5. The blanks of claim 1 wherein the weld lines are straight lines and curved lines.

6. Vehicle door blanks, comprising:

first components arranged in the form of a first blank for a front door, each component including an edge that is adjacent an edge of another one of the first components;

second components arranged in the form of a second blank having a periphery for a rear door, said periphery being different from the periphery for the front door, each second component including an edge that is adjacent an edge of another one of the second components; and

welds produced by a laser, connecting the first components along weld lines at the adjacent edges and connecting the second components along weld lines at the adjacent edges, each weld line of the first blank being collinear with a corresponding weld line of the second blank.

7. The blanks of claim 6 wherein the components are of sheet metal.

8. The blanks of claim 6 wherein each welded blank is in one-piece.

9. The blanks of claim 6 wherein the welds are substantially continuous along each weld line and extend through a thickness of the components.

10. The blanks of claim 6 wherein the weld lines are straight lines and curved lines.

11. A method for producing a blanks for vehicle doors comprising the steps of:

(a) forming first and second components for front doors blanks and rear doors blanks, respectively, of sheet stock having edges, a periphery of the front door blank being different from a periphery of the rear door blank;

(b) arranging the edge of each first component adjacent to a corresponding edge to form a front door blank;

(c) arranging the edge of each second component adjacent to a corresponding edge to form a rear door blank, such that the adjacent edges of the second components are collinear with corresponding adjacent edges of the front door blank; and

(d) interconnecting the first components to form a front door blank, and interconnecting the second components to form a rear door blank by welding the adjacent edges together.

12. The method of claim 11 further comprising the step of stamping the blanks to form a door panel.

13. The method of claim 11 further comprising the step of stamping the blanks to form a periphery and a window opening of an inside panel for a door panel.

14. The method of claim 11 wherein step (d) further includes forming the blank by laser welding the adjacent edges.

15. The method of claim 11 wherein steps (a) and (b) further includes forming the component having edges that are straight lines and curved lines.
