Abstract
A three-piece tailor welded blank vehicle door structure includes a periphery defined by a bottom portion, a pair of opposing side portions, a top portion, and an inclined portion. A first thickness gage sheet material portion is disposed generally along the door hinge side of the door structure. A second thicker gage sheet material portion is disposed generally along the door latch side of the door structure. A thinner gage sheet material portion is disposed between the first and second thickness gage sheet material portions, whereby the overall weight of the vehicle door is reduced.
