Abstract
A CAE NASTRAN based analysis along with GM internal software provides the capability to morph math surfaces that represent the clamped state of components in a weld station. These surfaces can clearly show the interference and gaps between mating flanges. Section plots are the method of detecting and dimensioning the weld mismatch. The sheet metal die changes for fitting the flanges together and correcting excessive weld flange gaps or interference are determined. Another morphed CAD model of the corrected stamping shape is sent to the die plant for guiding the die changes.
