Abstract
The present disclosure relates to methods by which a warped workpiece is reconfigured in a pre-determined manner to reduce a separation between the warped workpiece and a joining workpiece. The warped workpiece is reformed/reshaped, prior to joining, by softening material of the warped workpiece through application of a predetermined amount of energy at or near warping and using a directional force applied to a first surface of the warped workpiece, thus reducing a separation space at a joining interface of the warped workpiece and joining workpiece.
