Patent ID: 8614409

Claim:
An inductor assembly for treatment of a workpiece, which comprises: a body for positioning adjacent to the workpiece and movable relative to the workpiece, the body comprising a primary conductive portion for connection to a power source and capable of being positioned sufficiently close to the workpiece to effect induction heating of the workpiece when the workpiece is being treated, the primary portion conducting electric current from the power source to generate a magnetic field that inductively heats a portion of the workpiece; and a secondary conductive portion capable of being positioned adjacent to the workpiece when the workpiece is being treated, the secondary portion electrically insulated from the primary portion, the secondary portion being separate from the workpiece, the secondary portion receiving an induced electric current from the primary portion and being sufficiently close to the primary portion to shape the magnetic field generated by the primary portion that inductively heats a portion of the workpiece.
