Appl. No.:

7/925955

Abstract:

A system for negating remnant magnetic fields in a weld joint between two workpieces includes a controller and an electromagnet with two feet that form the pole pieces. The electromagnet feet are formed with surfaces that provide a substantial area for magnetic flux coupling with each workpiece on either side of the weld joint. Inside and outside surface pairs on the electromagnet feet permit effective placement of the electromagnet on the outside or inside of right angle corners formed by two workpieces to be welded. The electromagnet feet may be rotatively connected to the core to accommodate various workpiece configurations. The controller includes an autotransformer and two separate manually operable current controls.
