Abstract
A method and a device for modifying the energy-applying surface of an ultrasonic welding horn to join two complex thermoplastic parts by applying a thin film to the surface of the horn is disclosed. The thin film is applied to insure that a proper weld occurs along a complex and intricate pattern of energy directors located between the parts.
