ABSTRACT:
The invention relates to electrophoretic immersion lacquering of objects, e.g. the bodies of automotive vehicles, wherein the object which is to be lacquered is immersed into lacquer immersion basin containing a lacquer fluid. An electric field is produced by the object in its capacity as an electrode with at least one counter electrode. In order to determine the thickness of the lacquer layer applied in said manner, the electric charge flowing through the object during the immersion lacquering process and the surface of the object exposed to the lacquer fluid are determined in order to determine the thickness of the lacquer layer therefrom. The thickness of the lacquer coating can thus be determined during the immersion lacquering process, resulting in fewer rejects.
