摘要：The described embodiments relate generally to ultrasonic welding and more particularly to performing an ultrasonic welding operation while rotating one part relative to a mating part. A non-uniform energy director can be disposed along a mating surface of a first part. The energy director can maintain a constant cross-sectional area while having a smaller height near a pivot point for the rotation and a larger height away from the pivot point. The varying height of the energy director can allow the tip of the energy director to come in contact with a second part rotating relative to the first part at approximately the same time during the ultrasonic welding process.

主权项：1. A method for ultrasonically welding a first part to a second part, comprising: forming an energy director on a surface of the first part configured to mate with the second part, wherein the energy director has a non-uniform cross-section; and applying a vibrational energy to the energy director while rotating the second part relative to the first part; wherein a height of the non-uniform cross-section increases proportional to a distance from an axis of rotation for the second part, the increase in height being configured to allow an entirety of the energy director to contact a mating surface on the second part while applying the vibrational energy.
