Ultrasonic welding electrode, welding assembly including the sonotrode and method of welding with the aid of the said sonotrode

摘要

- Ultrasonic welding. - The invention relates to an ultrasonic welding sonotrode for materials in the form of sheets which are woven or non-woven, characterised in that it includes a working body (2) in the form of a tulip (bellmouth) flared out from its longitudinal axis (x-x') of revolution, the said body being, on the one hand, hollowed in its flared-out central part around the longitudinal axis (x-x') in order to define a crucible (7), and a peripheral working rim (border) (5) generating radial welding and, on the other hand, having an axial length (L) which is a function of the wavelength of the ultrasonic vibrations. - Application to a welding sonotrode for materials in the form of sheets which are woven or non-woven.
