Claims20
A stamped part comprising:
- a first blank;
- a second blank;
- and
- a weld joining the first blank to the second blank, the weld including opposing ends,
- wherein the weld is machined to remove a weld portion at at least one of the opposing ends of the weld along an entire thickness of at least one of the first and second blanks to form a cutout extending along the entire thickness of the at least one of the first and second blanks and between adjacent edges of the first and second blanks before the first blank and the second blank joined by the weld is stamped to form the stamped part.

A stamped part comprising:
- a first blank;
- a second blank;
- and
- a weld joining the first blank to the second blank, the weld including opposing ends,
- wherein the stamped part is formed by:
- welding the first blank to the second blank to form a tailor welded blank;
- removing a weld portion at at least one of the opposing ends of the weld from the tailor welded blank to form a cutout at the at least one of the opposing ends and extending along a thickness of the tailor welded blank and between adjacent edges of the first and second blanks to form a finished tailor welded blank;
- and
- stamping the finished tailor welded blank into the stamped part in a direction perpendicular to the first and second blanks.
