摘要： A device for welding rod-shaped electrical conductors and a sonotrode for such includes a compression space for receiving two connection regions of the conductors to be connected, said connection regions extending in a first axial direction (x-axis), the compression space being defined by a working surface of a sonotrode, which transmits ultrasonic vibrations, and a counterface of an anvil at two opposite sides in a second axial direction (z-axis) and by a boundary surface of a slider element, displaceable in the second axial direction (z-axis), and a boundary surface of a boundary element on two opposite sides in a third axial direction (y-axis). In a special contact zone, which is a section of the working surface of the sonotrode and serves to subject at least one connection region to ultrasonic vibrations, the working surface has a surface configuration that differs from a contact zone formed by the remaining working surface.

摘要： A method for determining the compression level of a node by compacting and welding electrical lines inserted into a compression chamber of an ultrasonic welding system, the compression chamber having an adjustable height and width. The method includes inserting the lines into the compression chamber, compacting the lines, determining the compacting cross section of the compacted lines, determining the actual total cross section via a correlation function taking the compacting cross section into account, welding the compacted node with a welding parameter set, determining the welding dimension from the height (h2) and width (b) of the compression chamber after welding, and calculating the compression level based on the actual total cross section and the welding dimensions.

摘要： An ultrasonic welding method includes: arranging the contact element and a first conductor portion of a first conductor between an anvil and a sonotrode; welding the contact element to the first conductor portion, where the anvil and the sonotrode are moved relative to each other in opposite directions to press the first conductor portion and the contact element against each other, and the sonotrode vibrates with ultrasonic vibrations; arranging the contact element and a second conductor portion of a second conductor, which is made of a different electrically conductive material than the first conductor, between the anvil and the sonotrode so that the second conductor portion lies between the first conductor portion and the sonotrode; welding the first to the second conductor portion.

摘要： 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.
