摘要： An electrical connection includes an electrically conductive first contact member, an electrically conductive second contact member, an interface, and an attachment. The first contact member includes a first contact surface for passing current. The second contact member includes a second contact surface for passing current that directly contacts the first contact surface. The interface includes one of a cold weld and a fused section that physically joins the first contact member and the second contact member, and that forms a primary conductive path between the first contact member and the second contact member. The interface is formed by ultrasonic vibration of the first contact surface relative to the second contact surface. The attachment is separate from the interface and mechanically joins the first contact member and the second contact member. A method for forming the electrical method is also provided.

摘要： A method is disclosed for forming corrosion-resistant joints in a plurality of overlapping thin metal sheet workpieces, at least one of which comprises at least 85% by weight of magnesium sheets. The fastener is a fiber-reinforced polymer rod shaped and sized for insertion into a coaxial opening formed in each sheet and subsequently upset on each end to form a head. The workpiece sheets are deformed to form mechanically-interfering features which cooperatively complement the strength of the fastener, under at least some joint loading patterns. The method may be used for other workpiece and fastener compositions.

摘要： A method for connecting individual lithium ion cells into a battery suited for powering an electric or hybrid vehicle is disclosed. The cell current collectors are electron beam welded to one another and to a connector tab in an substantially oxygen-free atmosphere. The cell current collectors and the connector tab are temporarily secured with a clamp, one portion of which has an opening. The electron beam size may be controlled, by magnetic coils and by the extent of electron scattering by the gas atmosphere, to minimally fill the clamp opening to minimize any irradiation of the clamp. The beam or the workpieces may be displaced, if required, fuse the entire opening area. A similar procedure may be followed to weld a plurality of connector tabs to a busbar.
