Apparatus and processes for protecting an ultrasonic welding horn using a thin-film separator

摘要

An apparatus and processes for protecting an ultrasonic welding horn (504) during welding of polymeric composites use a thin separator or thin membrane (502) configured to transmit high frequency sound vibrations while the horn (504) is kept isolated from molten workpiece material. Systems and methods of welding together polymeric composites use a conductive mechanical interface to reduce cycle time, compensate for any asperities, and increase weld accuracy and joint strength.
