An improvement to a cathode used in an electrorefining or electrowinning of copper. The cathode has a solid copper head bar with a horizontal groove on its undersurface. The upper edge of a stainless steel flat sheet has several holes along its width and is vertically inserted into the groove. The stainless steel sheet is then mechanically attached to the copper head bar by pressing the copper head bar against the stainless steel at the perforated points along the head bar. To increase the joint strength, the stainless steel sheet may be welded to the copper head bar at its upper edges at the underside of the head bar.
