Abstract: An ultrasonic horn reduces the likelihood of damaging a plurality of stacked sheets of metal foil when the stacked sheets and a metal member are ultrasonically bonded by applying ultrasonic vibration to the stacked sheets. An ultrasonic horn is used for ultrasonically bonding a plurality of stacked sheets of negative electrode foil and a negative electrode collector plate by applying ultrasonic vibration to the stacked sheets of negative electrode foil. The horn includes a horn body, a first protrusion having a first surface that is a curved surface and protruding from an opposing surface of the horn body facing the anvil toward the anvil, and a second protrusion provided at a center of the first surface of the first protrusion and protruding toward the anvil. The second protrusion includes an end surface that is a planar surface and a second surface connecting the end surface and the first surface.

Abstract: A tank including at least first and second portions connected by a connection ring and weld seams obtained by means of a friction welding method. The connection ring includes at least a first cylindrical portion fitted in the end of the first portion, at least a first shoulder protruding toward the outer zone of the tank relative to the first cylindrical portion and at least a first transverse web positioned approximately in the same transverse plane as the first shoulder. According to this configuration, the first cylindrical portion and the transverse web ensure that the forces generated by a friction welding head during the production of the weld seam which enables the tank to be closed are absorbed.

Abstract: An ultrasonic welding device includes a sonotrode with a sonotrode surface, a lateral slide with a lateral slide surface, a touching element with a touching surface and an insertion chamber for inserting joining parts. The insertion chamber is defined in a first axial direction (y) on a first side by the sonotrode surface and in a second axial direction (x) on a second side by the lateral slide surface and on a third side opposing the second side by the touching surface. Furthermore, the ultrasonic welding device includes a first receiving element with a first stop edge and a second receiving element with a second stop edge. The first receiving element and the second receiving element are arranged to be movable in relation to each other between a starting position and an end position.
