Zusammenfassung:	A device for producing a spring wire includes a wire production apparatus which is designed such that a spring wire can be produced from a raw material, in particular by drawing; a checking unit which is designed such that the spring wire can be checked for flaws, in particular material flaws and surface flaws; and a laser marking unit which is designed such that defective regions of the spring wire, in particular regions of the spring wire having material and surface flaws, can be marked with a laser marking such that part of the surface of the spring wire can be removed or part of the surface of the spring wire can be tempered in such a manner that the color of the surface of the spring wire is changed in this part. The wire production apparatus is designed such that the spring wire can be guided past the checking unit and past the laser marking unit.
