BIW (Body in white) refers to the stage in automobile manufacturing in which a car body's sheet metal components have been welded together. Body in White suggests the term derives from the appearance of a car body after it is dipped into a white bath of primer. In car design, the Body in White phase refers to the phase in which the final contours of the car body are worked out, in preparation for ordering of the expensive production stamping die. Extensive computer simulations of crash worthiness, manufacturability, and automotive aerodynamics are required before a clay model from the design studio can be converted into a Body in White ready for production. Welding requires specialized fixtures to accurately hold the work piece geometrically during the welding operation.
