Abstract: A spin fastening system includes a first member and an adhesive layer applied to the first member. A second member is positioned in contact with the adhesive layer. At least a portion of the adhesive layer is cured after the second member is positioned in contact with the adhesive layer to render at least the portion of the adhesive layer substantially rigid. At least one spin fastener is inserted successively through each of the second member, the cured portion of the adhesive layer, and the first member.

Abstract: A riveting system, for use in mechanically linking adjacent workpieces, including a rivet having a height greater than a sum of thicknesses, measured along a line of riveting, of the workpieces being linked, so that the rivet can pass fully through the workpieces. The system also includes a riveting die, which may be a separate product. The die includes a protrusion extending from a peak toward a transition point; and a trough having a trough surface. The trough surface includes a trough inner wall, extending from the transition point to a trough bottom, and a trough outer wall, extending from the trough bottom to a trough outer edge.

Abstract: Methods and systems for joining multiple workpieces are provided. In one example, the method includes dispensing adhesive on a first workpiece. A second workpiece is contacted with the adhesive such that the adhesive is disposed between the first and second workpieces. Resistance heating is produced in the first and second workpieces at first processing conditions to partially cure the adhesive and affix the first and second workpieces together to form a partially cured, adhesive-joined workpiece assembly. The partially cured, adhesive-joined workpiece assembly is exposed to heat at second processing conditions to substantially fully cure the adhesive.

Abstract: Welding electrodes, methods, and vehicles are provided. The welding electrodes include a body that includes a weld face on a distal end of the body configured to contact a workpiece and apply an electrical current thereto. The body has a maximum diameter of 13 millimeters or less. The welding electrode includes an insulative material covering at least a portion of the body, the insulative material configured to mitigate current shunting upon contact between the insulative material and a workpiece of a workpiece stack-up while using the welding electrode to resistance weld the workpiece stack-up.

Abstract: Methods for ultrasonic welding of thermoplastic polymer workpieces and assemblies made therefrom are provided. The method may comprise disposing a first region of a first thermoplastic polymer workpiece and a second region of a second thermoplastic polymer workpiece between an ultrasonic horn and an anvil of an ultrasonic welding device. The first workpiece has a preformed deformation and at least one of the first and/or second workpieces has an adhesive precursor applied thereto. The ultrasonic horn or anvil seats within the preformed deformation. Ultrasonic energy is applied from the ultrasonic horn to create a weld nugget between the first and second workpieces. The assembly thus formed has a green strength sufficient to be further processed immediately. The methods provide a robust weld joint with controlled adhesive bondline thickness.
