ABSTRACT:
A method for the electrodeposition coating of workpieces conveyed in an electrodeposition bath, wherein voltage applying means is provided in a plurality of stages of not less than three in the conveying direction of the workpieces. Voltage is increased at the first stage, and the multiple stages voltage applying means is initiated after the workpieces reach a submersion area where the workpieces are completely submerged in the paint contained in the electrodeposition bath. Voltage application at the final stage of the voltage applying means is terminated before the workpieces exit from the submersion area. By this method, the thickness of the electrodeposition film can be made uniform so that there is no difference in film thickness between lower and higher workpieces or in the lower and upper parts of a workpiece.
