<p>A method for the electrodeposition coating of workpieces (4a, 4b) conveyed in an electrodeposition bath (1, 22), wherein voltage application means is provided in a plurality of stages in the conveying direction of the workpieces (4a, 4b). In the method, the type of workpiece (4a, 4b) being conveyed is detected, and the length of time to apply voltage to the workpiece (4a, 4b) in the bath (1, 22) according to the type of workpiece (4a, 4b) 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 (4a, 4b) with the most suitable electrodeposition film thickness even in a line where workpieces (4a, 4b) having different required film thicknesses are present.</p> |
