Abstract

An apparatus and processes for protecting an ultrasonic welding horn (504) during welding of polymeric composites, use a thin separator, or membrane (502) configured to transfer high-frequency acoustic vibrations while keeping the horn (504) isolated from molten workpiece material. Systems and methods for welding polymeric composites, use a conductive mechanical intermediary, reducing cycle time, compensating for any surface unevenness, and improving weld accuracy and connection strength.

Description

technical field [0001] The present disclosure relates generally to ultrasonic welding, and more particularly to apparatus and processes for protecting ultrasonic welding corners during welding of polymer composites using thin separators or membranes configured to transmit high frequency acoustic vibrations while Keep corners isolated from molten workpiece material. [0002] The present disclosure also relates to systems and methods for welding polymer composites together using conductive mechanical intermediates to reduce cycle time, compensate for any surface unevenness, and improve weld accuracy and joint strength. Background technique [0003] In automotive manufacturing, polymer composites are increasingly used due to their excellent properties, including light weight, high conformability or formability, robustness and durability. Some composites are also tintable and can be finished to have most any desired texture. [0004] Increased use in automobiles includes, for ...
