Abstract
There is disclosed a high power induction heating coil for use in thermoplastic welding where a metallic susceptor is imbedded in a composite assembly and is heated by eddy currents generated by the coil. The coil is comprised of several windings of Litz wire composed of multiple individually insulated strands of copper wire. The coil is wound on a circular E core having a coolant conduit through the center of the core. Coolant is introduced through the central core and returned by circulating through the loosely wound coil to the coolant source.
