| 20090255908 | WELD ELECTRODE FOR ATTRACTIVE WELD APPEARANCE - Weld faces of electrodes for resistance spot welding are formed with a suitable area of protrusions and/or intrusions. The size, shape, and elevation or depths of the protrusions or intrusions are determined for the formation of suitable spot welds in and between metal workpieces such as aluminum or steel panels for vehicle bodies. The protrusions or intrusions are also conceived and used to form an image on at least a visible surface of the welded article to produce an attractive appearance on the surface of the welded sheet. | 10-15-2009 |
| 20090278396 | CORROSION ISOLATION OF MAGNESIUM COMPONENTS - A vehicle component, such as a wheel, is formed of a magnesium alloy for weight reduction in an automotive vehicle. It is expected that the wheel will be attached to other vehicle wheel-related componenets that are formed of metal compositions (for example, steel or cast iron components) that may lead to the corrosion of the magnesium wheel. Such attachment surfaces of the magnesium wheel are oxidized to form an integral and durable oxide layer on the magnesium wheel. When the magnesium wheel is attached to vehicle wheel supporting components of other alloys, the oxide layer-coated surfaces of the magnesium wheel are electrochemically isolated from the non-magnesium materials to prevent oxidation of the wheel or attached components. | 11-12-2009 |
| 20090302009 | ELECTRODE FOR SPOT WELDING - Spot welding electrodes with generally dome shaped welding faces are provided with surface features for welding both aluminum alloy sheet assemblies and steel sheet assemblies. A raised circular plateau is formed on the central axis of the dome and, in one embodiment, a suitable number of round bumps are formed in concentric spacing from adjacent the circumference of the plateau toward the circular edge of the welding face. For welding steel workpieces the plateau mainly serves as the engaging feature of the electrode. Both the plateau and concentric bumps are used in penetrating light metal surfaces for suitable current passage. In another embodiment, the domed surface is shaped with concentric terraces for engagement with the workpieces. | 12-10-2009 |
| 20100035080 | Corrosion resistant laminated steel - Outer steel sheet-viscoelastic core laminates are often subject to corrosion in moisture-containing environments. Zinc-based alloys of aluminum, or of aluminum and magnesium, may be beneficially applied to the inner faces of the steel sheets or to both the inner and outer sheet faces. Substantially pure zinc coatings may be applied over the zinc-based alloys or over an otherwise bare outer steel sheet surface. Combinations of such zinc-based alloy coatings and substantially pure zinc coatings improve the corrosion resistance of the steel sheet-polymer core laminates while maximizing weldability and paintability. | 02-11-2010 |
| 20100258537 | WELDING LIGHT METAL WORKPIECES BY REACTION METALLURGY - Aluminum alloy workpieces and/or magnesium alloy workpieces are joined in a solid state weld by use of a reactive material placed, in a suitable form, at the joining surfaces. Joining surfaces of the workpieces are pressed against the interposed reactive material and heated. The reactive material alloys or reacts with the workpiece surfaces consuming some of the surface material in forming a reaction product comprising a low melting liquid that removes oxide films and other surface impediments to a welded bond across the interface. Further pressure is applied to expel the reaction product and to join the workpiece surfaces in a solid state weld bond. | 10-14-2010 |
| 20100276236 | DAMPED PRODUCT AND METHOD OF MAKING THE SAME - One exemplary embodiment includes a damped product. The damped product is composed of a sintered powder metallurgy material and has a first portion and a second portion. The first portion has a density that is greater in value that a density of the second portion. The different densities damp vibrations in the product when the product is vibrated. | 11-04-2010 |
| 20100282550 | MODE ALTERING INSERT FOR VIBRATION REDUCTION IN COMPONENTS - A component with a first number of natural modes of vibration. An insert may be coupled to the component. The insert may have a second number of natural modes of vibration which is a different number than the first number of natural modes of vibration of the component. The insert helps damp vibrations in the component when the component is vibrated. | 11-11-2010 |
| 20100294063 | FRICTION DAMPED GEARS - One exemplary embodiment includes a transfer gear that carries a friction damping component that damps vibrations in the gear. The friction damping component may be carried on or in a hub, a web, or both the hub and the web, and may include at least one non-bonded surface that contacts an adjacent surface. | 11-25-2010 |
| 20110094999 | APPLICATION OF SURFACE RELIEF TO SPOT WELDING ELECTRODES - The workpiece-contacting surface of the spot welding electrode may be suitably modified to incorporate a desired shape or form, generally comprising a depressed region outlining a recognizable shape, to form aesthetically-pleasing or functional features in the surface of a workpiece during resistance spot welding. Methods for creating the desired form in the spot welding electrode including abrasion, upsetting, and electrical discharge machining are disclosed. Preferably the electrode face is shaped and subsequently redressed during welding operations at the welding station. | 04-28-2011 |
| 20110143161 | COULOMB DAMPING FEATURES USING ULTRASONIC WELDING - Selected surface regions of coulomb vibration damping strips are bonded face-to-face by ultrasonic welding to a surface region of an article that may experience excessive vibration in use. In one embodiment, prior to welding, the intended facing side of the damping strip is treated to form surface regions that are oxidized, roughened, or coating so that the treated regions do not weld to the article surface. In another embodiment of the invention the ultrasonic welding process is controlled so as to produce regions (sometimes randomly interposed regions) of welded and non-welded regions between the damping strip and adjacent article surface. The unbonded regions of the otherwise welded strip lie in closely-spaced, interfacial, frictional contact with the adjacent article surface to damp vibration in the article. Other processes may be used for welding a damping strip to a surface of an article while leaving un-bonded, friction damping regions between regions of the damping strip and the facing surface of the article. | 06-16-2011 |
