  • the at least one spherical or kugeiä Anlagen shaped element of the functional head is rotationally symmetrical with respect to a normal direction of the foot area.
  • the terms "spherical” or “ball-like” generally include “round” or "curved”, in particular "convex curved geometries”.
  • the foot region of such a fixing element is intended to be welded to a component or welded onto a component, so that the fixing element protrudes from the component as a "male fixing element”.
  • the fixing element can be produced in one piece, ie the foot region and the functional head can be produced in one and the same manufacturing process, eg by cold extrusion, electromagnetic forming, etc.
  • the foot region and the functional head can also be manufactured in separate processes and subsequently joined together to form the fixing element be, for example Capacitor discharge welding, lift-arc welding, resistance welding, etc.
