Abstract
A system electroplates the interior or exterior cylindrical surfaces of an elongated workpiece, such as a pipe or shaft. The workpiece is continuously electroplated with metallic solutions via a traveling anode that gradually plates along the axial length of the workpiece instead of plating the entire part or large portions of the part at one time.
