摘要： 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.

摘要： A method for the electrodeposition coating of workpieces conveyed in an electrodeposition bath, wherein voltage application means is provided in a plurality of stages in the conveying direction of the workpieces. In the method, the type of workpiece being conveyed is detected, and the length of time to apply voltage to the workpiece in the bath according to the type of workpiece by changing the number of stages to be electrically coupled among the plurality of stages of the voltage application means. By this method, it becomes possible to provide each workpiece with most suitable electrodeposition film thickness even in a line where workpieces having different required film thicknesses are present.
