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.

Device for welding rod-shaped electrical conductors and sonotrode for such a device

The invention relates to a device and to a method for producing a tested weld joint between two contact elements (), which are joined together in a welding plane S, comprising a compressing space for accommodating the contact elements (), said compressing space being delimited by a work surface of a sonotrode, which transmits ultrasonic oscillations, and a counter-surface () of a counter-electrode () in a first axial direction at two opposing sides and by delimiting surfaces of opposing delimiting elements in a second axial direction at two opposing sides, said device comprising a test head () next to the compressing space, and said test head being able to be transferred from a position outside of the compressing space to a position within the compressing space in such a manner that the test head () is disposed within the open compressing space in a test mode of the device for subjecting a contact element () of the previously produced weld joint to a shear force essentially oriented parallel to the welding plane S, and said test head () being disposed outside of the compressing space in a welding mode of the device for producing the weld joint.
