WELDING ELEMENT FOR WELDING A CONTACT ELEMENT TO A CONNECTING ELEMENT
The invention relates to a welding element (100) for a sonotrode for welding a connecting element (400) to a contact element (401), comprising a body (105) having a welding surface (110). The welding surface is designed to cause a bonded connection by means of ultrasonic welding between the connecting element and the contact element. The body is characterized in that the body is tapered in the direction of the welding surface in a transition area (120) adjacent to the welding surface.
