SYSTEMS AND METHODS FOR JOINING A WARPED WORKPIECE TO ANOTHER WORKPIECE

摘要

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.

1. A method, for joining a first workpiece having a deformity to a second workpiece, comprising:
positioning the first workpiece adjacent the second workpiece such that a first surface of the first workpiece having the deformity is near a tip of a weld horn and a second surface of the first workpiece is adjacent a first surface of the second workpiece; softening material of the first workpiece by applying a first predetermined amount of energy from the weld horn to the first surface of the first workpiece at or near the deformity; applying, after starting to soften the material of the first workpiece, a force to the first surface of the first workpiece at or near the deformity, causing the first workpiece softened to reform to a position generally parallel with a first surface of the second workpiece, thus reducing a separation space at a joining interface formed by the second surface of the first workpiece and the first surface of the second workpiece; and applying a second predetermined amount of energy, being greater than the first predetermined amount of energy, to the first workpiece reformed to form a welding joint at an interface between the first workpiece and the second workpiece.
