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 method of riveting a first substrate and a second substrate with a rivet includes delivering a first ultrasonic pulse to a respective exterior surface of the first substrate at a predefined target area, via an ultrasonic device. The first ultrasonic pulse is configured to soften the first substrate at a first softening temperature. The method includes attaching a crust layer on a rivet head of the rivet. A second ultrasonic pulse is delivered to the predefined target area to soften the crust layer at a second softening temperature, via the ultrasonic device. A surface profile of the crust layer is fashioned via compression of a horn inner cavity of the ultrasonic device over the crust layer. The crust layer is cooled to harden into a seal configured to prevent entry of moisture between the rivet and the respective exterior surface of the first substrate, thereby reducing galvanic corrosion.
