    摘要： An assembly dissimilar material members includes: a first joining-target member (12) made of resin; a second joining-target member (14) made of metal; and a rivet (16) made of metal. The rivet includes a shaft-shaped portion (30), and a head (36) integral with a first end of the shaft-shaped portion, and disposed outside the hole. The shaft-shaped portion includes: a shaft (32) ; an enlarged diameter portion (34A) ; and a punching portion (34) joined to the second joining-target member via the welded portion. A hole (24) of the first joining-target member includes: a small-diameter hole portion (26) formed at an outer circumference of the shaft, and having an inner diameter dimension equal to a diameter dimension of the enlarged diameter portion; and a large-diameter hole portion (28) formed at an outer circumference of the punching portion, and having an inner diameter dimension greater than the diameter dimension of the enlarged diameter portion.

    摘要： An apparatus and method for fastening layers of non-ferrous alloys, like aluminum, magnesium and copper utilizes a steel fastener and a spot welding machine. The fastener and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the fastener to penetrate the aluminum. A weld zone between the fastener and the various layers creates an internal weld. The fastener has a rough shaft that is coated by the molten weld zone and is hard to withdraw on solidification. Layers of non-conductive materials like plastics and ceramics may also be affixed to a conductive layer using a fastener made from a compatible material that extends through a pilot hole and welds to or penetrates a conductive layer. The fastener may have projections that initially reduce contact area with the stack.

    摘要： The invention provides a method of joining dissimilar materials, such as aluminum to steel, by applying low pressure and heat to minimize distortion of the materials and the heat affected zone. The method includes applying current to a weld element, at least partially melting a portion of the first material with the heated weld element, and passing through the at least partially melted portion of the first material with the weld element. The method further includes contacting the second material with the heated weld element, and melting a portion of the weld element and a portion of the second material in contact with one another to form a weld. The weld element is designed with a head to trap the first material between the head and the second material, and a vent for receiving the at least partially melted first material as the weld element passes through.
