Abstract

Das Verfahren zum Reinigen des beim Drahtlichtbogenspritzen verwendeten Drahtes von lockeren Verunreinigungen besteht darin, daß in die den Draht umgebende stromführende Hülse seitlich ein Spülgas eingebracht wird, welches die auf der Oberfläche des Drahtes befindlichen lockeren Verunreinigungen in der Gegenrichtung der Vorschubrichtung des Drahtes entfernt.

Figure 00000001
The method of cleaning loose impurities in the wire used in wire arc spraying is to introduce a purge gas laterally into the current-carrying sleeve surrounding the wire, which removes the loose impurities on the surface of the wire in the opposite direction to the direction in which the wire is fed.
