Abstract: An apparatus and method for fastening dissimilar materials like steel, plastic and aluminum. A resistance welding fastener having multiple layers may be used with or without a sealant. The fastener may be used to form an aluminum covered steel laminate via a hemming pattern of attachment. The fastener may have a solid shaft or have an extended reach and have features for interacting with the welding electrode. A variety of electrode tips may be employed to cooperate with the fastener.

Abstract: 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.

Abstract: This invention discloses a method for calculating gripper trajectories in forming equipment. The method utilizes a computer aided design (CAD) or a computer aided engineering (CAE) computer program to calculate the appropriate location, speed, controller commands, and trajectory for each gripper used during a forming process.

Abstract translation: 用于紧固诸如钢和铝的不同金属的装置和方法利用钢铆钉和点焊机。 铆钉和金属被堆叠，来自焊机电流的热量使较低熔点的铝软化，允许铆钉穿透铝并焊接到钢层。 紧固件可以用于连接具有多层不同材料的堆叠，并且可以用于将由钢或钛制成的螺纹插座或螺柱施加到铝或镁合金结构。 诸如塑料和陶瓷的非导电材料层也可以使用由穿过引导孔延伸的相容材料制成的紧固件固定到导电层上。
