Publication number: 20120280019Abstract: An ultrasonic welding apparatus and method for detaching or effecting release of an ultrasonic welding tool stuck or attached to a weldment. The method includes the step of utilizing a mechanism mounted adjacent to the ultrasonic welding tool to hold the weldment in position during welding and/or while the ultrasonic welding tool is withdrawn and, if necessary, using the mechanism to detach the weldment from the ultrasonic welding tool. The method contemplates providing a twist, rotary or axial motion to one of the ultrasonic welding tool or weldment to effect release of the ultrasonic welding tool. The apparatus may include a clamp member having a distinct clamping area or pad located adjacent to the sonotrode or anvil of the ultrasonic welding tool. The clamp mechanism provides vibration control, noise mitigation, and a more uniform boundary condition during welding and facilitates part release upon the completion of the welding process.Type: ApplicationFiled: June 21, 2012Publication date: November 8, 2012Applicants: JAGUAR CARS LIMITED, FORD GLOBAL TECHNOLOGIES, LLCInventors: Larry Van Reatherford, Jan Skogsmo, Daniel Edward Wilkosz, Elizabeth Therese Hetrick, Ray Jahn

Patent number: 6691909Abstract: An apparatus and method for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode includes a contact surface wherein a fluid is deposited on the contact surface prior to the welding process. The fluid may be applied in different ways, including providing an aperture in the contact surface of the sonotrode. In addition, the sonotrode may be cooled below the dew point of the surrounding atmosphere thus causing moisture to form on the contact surface of the sonotrode. Cooling the sonotrode to a temperature above the dew point also reduces sonotrode adhesion during the ultrasonic welding process.Type: GrantFiled: October 10, 2001Date of Patent: February 17, 2004Assignee: Ford Global Technologies, LLCInventors: Jan Birger Skogsmo, Larry Van Reatherford, Oludele Olusegun Popoola, Ray Jahn, Vijitha Senaka Kiridena

Patent number: 6651872Abstract: The present invention is a disassembly apparatus and method for disassembling a workpiece having at least two layers joined together by welding or other bonding processes at bonding points. The method includes the steps of securing the workpiece into a fixture to prevent movement of one of the layers. The apparatus includes a sonotrode and a holding device. The method further includes moving the sonotrode to contact the workpiece to apply a predetermined amount of contact pressure to the workpiece. The sonotrode in contact with the layer on a side opposite the anvil is then vibrated at a predetermined frequency until the layers become disassembled. An apparatus for performing the method is also disclosed.Type: GrantFiled: October 10, 2001Date of Patent: November 25, 2003Assignee: Ford Global Technologies, LLCInventors: Carl Frederick Johnson, Elizabeth Therese Hetrick, Oludele Olusegun Popoola, Ray Jahn

Patent number: 6464933Abstract: A method of fabricating a foamed metal structure using a powder supply of metal particles, comprising: (a) introducing the powder supply along with foaming agent particles into a propellant gas to form a gas/particle mixture stream; (b) projecting the mixture stream at a critical velocity of at least sonic velocity onto a metallic substrate to create a deposit of pressure-welded metal particles containing the admixed foaming agent; and (c) subjecting at least the coating of the substrate to a thermal excursion effective to activate expansion of the foaming agent while softening the metal particles for plastic deformation under the influence of the expanding gases.Type: GrantFiled: June 29, 2000Date of Patent: October 15, 2002Assignee: Ford Global Technologies, Inc.Inventors: Oludele Olusegun Popoola, Ray Jahn, Robert Corbly McCune
