Patent number: 7126076Abstract: A method for repairing defects in a metallic substrate including the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; bringing a first electrode and a second electrode in contact with the consumable slug and applying a pressure to the consumable slug; and transmitting electrical current between the electrodes for a period, thereby resistively heating the consumable slug and the metallic substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under the pressure of the electrodes. The electrodes are then removed from contact with the consumable slug and excess material may be removed. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers to add additional defect filling material, retain the pool, and seal the pool from atmosphere.Type: GrantFiled: February 5, 2004Date of Patent: October 24, 2006Assignee: Edison Welding Institute, Inc.Inventors: David P. Workman, James L. Reynolds, Jr., Timothy J. Trapp, Jerry E. Gould

Patent number: 6545244Abstract: A welding arrangement comprises first and second parts to be welded with an edge portion of the first part and an edge portion of the second part juxtaposed to form a weld zone. An electrically-conductive sheet(s) with a higher melting temperature than a melting temperature of the first and second parts are placed over the weld zone and a force application device is used to apply a lateral compressive force to the weld zone. First and second electrodes are placed in contact with the electrically conductive sheet(s) which are resistively heated and in turn conductively heat the weld zone.Type: GrantFiled: August 27, 2001Date of Patent: April 8, 2003Assignee: Edison Welding InstituteInventors: Jerry E. Gould, Lawrence R. Lehman, David P. Workman

Patent number: 5633093Abstract: An apparatus for balancing an aluminum drive shaft uses a transition material to attach steel counterweights to the aluminum drive shaft. The transition material is disposed between an outer surface of the aluminum drive shaft and an inner surface of the steel counterweights. A resistance welding process is then applied to the aluminum drive shaft, the steel counterweights, and the transition material to resistance weld the inner surface of the steel counterweights to the outer surface of the aluminum drive shaft. The transition material has a first surface adjacent to the aluminum drive shaft and a second surface adjacent to the steel counterweights, with the first surface being aluminum and the second surface being steel. In a method of balancing an aluminum drive shaft, a resistance welding process is applied to the aluminum drive shaft, the steel counterweights, and the transition material to resistance weld the inner surface of the steel counterweights to the outer surface of the aluminum drive shaft.Type: GrantFiled: August 19, 1994Date of Patent: May 27, 1997Assignee: Dana CorporationInventors: Donald A.
