1. A method of fastening a fastening element consisting of a first material to a substrate consisting of a substrate material, the method comprising:
creating a blind hole defining a depth direction with a blind hole diameter in the substrate,
providing a fastening element which has a shaft defining a fastening direction having an end face pointing in the fastening direction and having a circumferential surface adjoining directly to the end face, wherein the end face has outer dimensions,
driving the shaft into the blind hole to anchor the fastening element in the blind hole, wherein the outer dimensions of the end face exceed the blind hole diameter, so that when driven into the blind hole the shaft displaces a part of the substrate material in the depth direction and is welded on the substrate at the circumferential surface,, wherein the circumferential surface is slanted relative to the fastening direction, and wherein an angle of inclination of the circumferential surface relative to the fastening direction is between 1° and 6°.
