Abstract
A transformer, choke or the like includes a magnetic core assembled from two lamination packets formed of laminations layered in a given direction. The lamination packets have outer contacting surfaces defining a partition line therebetween. A weld seam transverse to the given direction fastens the contacting surfaces to one another and overlaps the partition line. A fastening element fastens the transformer, choke or the like to a floor or a wall. Upright tabs formed on the fastening element have free edges alongside the partition line being partially welded with the weld seam.
