Abstract: An ultrasonic welding device includes a sonotrode, an anvil, a touching element, a lateral slide, a stop element and a receiving chamber in which joining partners are received and which is defined by bordering components of the ultrasonic welding device. The receiving chamber is defined on a first side by the sonotrode and on a second side by the anvil. The receiving chamber is further defined on a third side by the touching element and on a fourth side by the lateral slide. The receiving chamber is further defined on a fifth side, extending transverse to the first to fourth sides, by the stop element. The first stop element is electrically conductive on its surface directed toward the receiving chamber in order to form a first electrode.

Abstract: The present invention includes: an ultrasonic horn (14) to which two ultrasonic vibrations can be input to excite a capillary (15) mounted to a front end with different frequencies in a Y-direction and an X-direction; and a control unit (50) which adjusts the respective magnitude of the two ultrasonic vibrations. The Y-direction is a direction in which the ultrasonic horn (14) extends. The control unit (50) adjusts the respective magnitude of the two ultrasonic vibrations to adjust a ratio (ΔY/ΔX) of amplitude of the capillary (15) in the Y-direction and the X-direction. Thus, degradation in the quality of the joining between wires and leads is suppressed.

Abstract: A method utilizing cold welding to prepare grain boundaries having different included angles includes using a device including a support member. Two bent members are arranged opposite to each other in the support member. One ends of the two bent members are both fixedly connected to the support member, one end, away from the support member, of any bent member is fixedly connected to a first sample, one end, away from the support member, of the other bent member is fixedly connected to a second sample, and the first sample and the second sample are arranged corresponding to each other. The bent member includes a first metal sheet and a second metal sheet having different thermal expansion coefficients. An angle between the first sample and the second sample during butt welding can be controlled by changing an included angle of a bimetallic sheet.
