摘要:
A method for controlling welding forces of a weld tip to a work piece during a vibration-welding process includes positioning an Active Material (AM) element adjacently to a welding interface, and varying a property of the AM element to regulate the welding force. The AM element may be disposed between the weld tip and a weld face thereof, or between the work piece and an anvil. The property may be varied as a function of heat generated by the welding process. A property of each of a plurality of AM elements may be independently and selectively varied via an energy source, or passively. A vibration welding system includes a weld tip and an AM element connected adjacently to a welding interface. The system regulates a welding force applied by the weld tip to a work piece during the welding process by varying a property of the AM element.
