Abstract: A method for welding a welded part to a component is carried out as arc ignition welding by use of direct current, having a bias current phase in which an arc is formed between the negatively polarized welded part and the component, and a subsequent main current phase for melting material to the joint. The welded part: a) is a galvanized sphere made of C10C having a roundness G500, wherein the size of any zinc inclusions under the surface of the sphere equals 10 micrometers at maximum, orb) is formed by welding a galvanized sphere made of C10C having a roundness G500, wherein the size of any zinc inclusions under the surface of the sphere equals 10 micrometers at maximum, to a connection element.

Abstract: An arrangement is provided for fastening a structural element, which has a retaining device that interacts with a T-stud, wherein the T-stud has a stud shaft and a stud head with an underhead having a contact surface for contacting at least one counter-surface formed on the retaining device. The stud shaft can be welded to a component. The at least one counter-surface of the retaining device is designed on a contact shoulder for the underhead of the stud head which encompasses the stud at least in part. A plurality of recesses are designed in the contact shoulder of the retaining apparatus, interrupting the counter-surface, wherein the contact surface of the underhead contacts the contact shoulder of the retaining apparatus in the plane of the countersurface.
