Filed:

Apr 10, 2006

Appl. No.:

11/401094

Inventors:

Paul P. Singh - Fremont CA, US
Ronald E. Musante - Los Altos CA, US
Brian H. Kariya - Los Gatos CA, US
Anthony P. Lee - White Lake MI, US

Assignee:

BAE Systems Land & Armaments L.P. - Arlington VA

International Classification:

F41H 5/02

US Classification:

89 3602, 89 3604, 89 3607

Abstract:

An interface includes a blast plate having plate structure, the plate structure being formed to substantially conform to a certain portion of an exterior margin of a hull of a certain vehicle and being semi-permanently mounted to the hull by mounting to certain mounting devices present on the exterior margin of the hull and having mounting structure for supportively mounting a standardized add-on device, the mounting structure being designed to facilitate the add-on device being readily mountable on and demountable from the plate structure, the plate structure having structural characteristics for acting to protect the hull from effects of a blast directed at the hull. A modular assembly and a blast plate are further included.

International Classification:

B23K 1124

US Classification:

219110

Abstract:

A method and apparatus are disclosed for analyzing the dynamic resistance of a resistance spot welding process to determine the time of an expulsion event and use that time as the weld completion time for controlling weld termination via a weld feedback signal, controlling automatic current stepping, and identifying maintenance needs. A preconditioning pulse is used to stabilize the weld process and aid in obtaining interpretable resistance information. After an initial blanking period the resistance curve is analyzed by calculating first and second derivative values and applying several algorithms that make possible the computer recognition of characteristic resistance curve shapes resulting from weld expulsion under good geometry, bad geometry and edge weld conditions.

Appl. No.:

6/883781

Inventors:

Gregory L. Nagel - Royal Oak MI
Anthony Lee - West Bloomfield MI
Warren D. Hill - Lake Orion MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B23K 1124

US Classification:

2191171

Abstract:

A method and apparatus are disclosed for resistance spot welding including applying a preconditioning pulse at the beginning of a welding process to stabilize the resistances at the interface of the sheets being welded and at the interface of the electrodes and the sheets. A current pulse is applied just after contact of electrodes and the workpiece when the electrode force is between about 10% and 75% of its final value to melt interface surfaces followed by a cooling time to permit dissipation of heat from the interfaces, and is finally followed by a conventional weld current schedule. The contact time is determined be electrically monitoring the conductivity between the electrodes as they are moved toward the workpiece. Alternatively, the applied electrode pressure is monitored to determine when sufficient electrode force is applied to the workpiece to achieve the proper resistance for the pulse application.
