Filed:

Oct 31, 1997

Appl. No.:

8/962550

Inventors:

Dawn Roberta White - Ann Arbor MI
Richard Lawrence Allor - Livonia MI
Jerald Edward Jones - Golden CO

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

B23K 3504
B23K 1130

US Classification:

219 912

Abstract:

A method for spot-welding aluminum workpieces with copper electrodes that comprises the steps of: (a) dissolving copper and one or more alloying elements X to yield an alloy that increases the liquidus of Al when dissolved in molten Al, super heating the alloy of copper and one or more elements X that normally have little or nor solubility in copper at room temperature, such super heating being a temperature at which X is soluble in copper, X being selected from the group of Mo, Ta, V, and W, elements that form monotectic or peritectic phases with copper and aluminum devoid of an eutectic, X being present in an amount of 4-15% by weight of the copper; (b) rapidly cooling the alloy to room temperature to retain such elements in solid solution; (c) either concurrently or subsequent to step (b), forming the alloy as an electrode shape; and (d) passing current through the electrode shape to effect spot-welding of the aluminum workpieces when pressed thereagainst while extending the welding life of the electrode. Super heating and rapid cooling may be carried out by atomizing a melt of Cu and X with a pressurized gas that directs the spray onto a target for further cooling and eventual working or shaping.

International Classification:

H01R 900
B23K 2012

US Classification:

228 563

Abstract:

An aluminum clip useful for being bonded to glass and serving as a terminal for an electrical lead circuit in or on such glass, comprising: an aluminum-based body having a cup shape. The cup shape having a substantially flat surface; an ultra thin pad of noble metal adhered to the substantially flat surface, the pad presenting a surface roughness in the range of 1-5 microns.

International Classification:

H01R 1373
H01R 1111

US Classification:

428630

Abstract:

An automotive body glass product, comprising: (a) a laminated glass having its perimeter painted to obscure the presence of applied adhesives; (b) conductive leads on or in the glass and having one or more conductive lead terminals; (c) an ultra thin pad of noble metal deposited onto a small zone of the glass in connection with at least one terminal; and (d) a conductive metal clip connected to the end of each lead path, said clip having a dimple thereof bonded to the pad by inertial welding of the dimple and noble metal pad material.

International Classification:

B23K 2012

US Classification:

2281145

Abstract:

A method of inertial bonding of a conductive metallic member to a fragile non-conductive member, comprising: (a) depositing a thin adherent conductive pad onto the fragile member to present a first friction creating surface: (b) forming the conductive metallic member with a second friction mating surface conforming essentially to the first friction creating surface; (c) bringing the first and second friction surfaces together with high relative movement transverse to the surfaces and with a gradually increasing forging force along an axis perpendicular to the surfaces to generate sufficient frictional heat therebetween to effect at least a galling or smearing of melted particles of said surfaces; and (d) abruptly ceasing the relative rotation and increasing forging force upon the attainment of such melted particles at the engaging interface between the surfaces.
