ABSTRACT:
A device for induction welding apparatus fashioned partly from a metal plate is disclosed. The metal plate is constructed so as to form an inductive loop for generating eddy currents in electrically conductive material placed adjacent thereto. The metal plate contains a groove for carrying a cooling medium; a second, similarly configured non-conductive plate is attached to the metal plate over said groove to allow passage of said cooling medium in said groove.
