Abstract:
1. A method for welding a sensor holding element to a component, in particular for a motor vehicle, using the torsional ultrasonic welding process, having a sonotrode for transmitting the vibrations generated by the welding process to the sensor holding element to be welded, wherein the sensor holding element is provided with a coupling surface for coupling the vibrations of the sonotrode, and the sensor holding element being provided, on the ring-shaped weld region facing the weld surface on the component, with coupling elements for coupling the vibrations induced by the sonotrode, so that the coupling elements melt during the welding process and thus weld the sensor holding element to the component, wherein protrusions which extend essentially perpendicularly to the ring-shaped weld region and which are situated in such a way that the melt substantially remains on the weld surface are used as coupling elements and wherein the protrusions are two coaxially situated rings which delimit the ring-shaped weld region.
