A method is used for a pair of bonding composite materials that are each provided with a melting material and a heat-resistant material. Each heat-resistant material includes a heat-resistant member and a binder member. The ceramic separators have ceramic layers that face each other and that are bonded. An ultrasonic wave is applied to the composite materials while applying a pressure thereto with a processing member. Also heat is applied to the binder members with a heating member. Here, the heater heats the binder members to a temperature that is greater than or equal to the glass transition temperature of the binder members and less than the melting point of the binder members.

The invention relates to a strapping device for strapping packaged goods with a strapping band, said strapping device being provided with a connecting device (5) designed as an ultrasonic welding device (9) in order to form a closure. The ultrasonic welding device (9) is provided with a sonotrode device (13) to which ultrasound generated by an ultrasound converter (10) can be transmitted, and the sonotrode device (13) has a contact surface (21, 24) in a provided region which contacts the strapping band. The contact surface is designed to contact a surface of the strapping band, and the sonotrode device (13) is designed to produce ultrasonic vibrations by means of the contact surface. The aim of the invention is to allow a more compact design for such strapping devices. This is achieved in that the contact surface (21, 24) of the sonotrode (11) is aligned at an angle which deviates from a right angle relative to the provided vibration direction of the sonotrode (11).
