Method for fabricating a laminated coil conductor for a high current coil which includes wrapping a layer of insulation around a rotatable shaped mandrel and then winding a plurality of copper sheets over the insulation as the mandrel is rotated. Solder is interposed between the copper sheets and between coolant tubes positioned on each end of each coil conductor. The assemblage is then removed from the mandrel and raised to a temperature to bond the copper sheets and coolant tubes together. The assemblage is then placed in a structural box and a plastic is injected into the box to fill any voids between the coil conductor and the box. An assembly of a plurality of coil conductors arranged in a high current coil according to the method is illustrated.
