Patent ID: 11165211

Abstract:
The invention relates to a device and to a method for producing a tested weld joint between two contact elements (11, 12), which are joined together in a welding plane S, comprising a compressing space for accommodating the contact elements (11, 12), said compressing space being delimited by a work surface of a sonotrode, which transmits ultrasonic oscillations, and a counter-surface (15) of a counter-electrode (16) 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 (27) 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 (27) is disposed within the open compressing space in a test mode of the device for subjecting a contact element (12) of the previously produced weld joint to a shear force essentially oriented parallel to the welding plane S, and said test head (27) being disposed outside of the compressing space in a welding mode of the device for producing the weld joint.
