Abstract: An apparatus for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode tip has a specific surface configuration, including a curvilinear shaped outer surface combined with a plurality of grooves and lands. Due to the curvilinear surface, the depth of the grooves gradually decreases near the outer edge or periphery of a contact surface of the sonotrode tip. Further, such a groove and land combination also provides a sharp edge or corner that reduces sliding of the tip on the workpiece and correspondingly reduces sticking. In addition, various types of coatings or inserts may also be used to reduce sticking of the sonotrode tip to the workpiece.
