INSULATED ELECTRODE FIXTURE FOR RESISTANCE WELDING AND METHOD OF WELDING USING SAME

Insulated electrode fixture has an electrically conductive body with a receiving channel configured to receive a workpiece and an insert that is electrically isolated from the electrically conductive body is located on the first side and circumferential to the receiving channel. During welding processes, portions of the surface of the electrode fixture are electrically insulated from contact by a weld upset by the electrically isolated insert. Variations include an electrically isolated insert located on or inset into the surface of the electrode fixture, an insert of a non-conductive material located on or inset into the surface of the electrode fixture, an insert with a coating of a non-conductive material located on or inset into the surface of the electrode fixture, a non-conductive coating on the electrode fixture (except for in areas designated for conducting the weld current during resistance welding), or combinations thereof.
