    摘要： An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.

    摘要： Method for connecting two or more metal sheets or profile parts, especially of an automobile body segment as well as said automobile body segment.A method is described for joining two or more metal sheets and/or profileparts of which typically one is a high strength steel with the following steps. a) mechanically joining in a force-locking or frictional manner the metal sheets or profile parts at one or more connecting sites and subsequently b) thermally joining the connecting sites by means of pressure welding. With the method according to the invention in particular in the motor vehicle sector automobile body segments can be produced which display qualitatively very high quality point weld joints.

    摘要： A connection unit for composites is provided to connect upper and lower plates that overlap each other. The connection unit includes a first connector having a central first downwardly-protruding portion configured to be inserted into an aperture in the upper plate and a peripheral first flange portion, a welding recess being formed in the first protruding portion. Additionally, a second connector has a central second upwardly-protruding portion configured to be inserted into an aperture in the lower plate and a peripheral second flange portion, a welding recess being formed in the second protruding portion. The first and second protruding portions are in contact with each other when inserted into the upper and lower plates, and the contact ends of the first and second protruding portions are welded to each other to secure the upper and lower plates to each other.
