<p>A method and device for modifying the energy-applying surface (14) of an ultrasonic welding horn (10) to join two complex thermoplastic parts (22, 24) by applying a thin film (16) to the surface (14) of the horn (10) is disclosed. The thin film (16) is applied to ensure that a proper weld occurs along a complex and intricate pattern of energy directors (32) located between the parts (22, 24).</p> |
