Defined in this specification are practical tolerances and requirements needed to achieve satisfactory weld quality when dealing with the production volumes associated with automotive structural parts made of aluminum. Gaps in the weld joints have a significant effect on structural performance and weld quality. Automatic and robotic arc welding requires specified part fit-up in the weld joints for consistent weld quality. Therefore, metal stampings and press-formed parts must be made to produce weld joint fits within the ranges allowed by this specification.
