Abstract: A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.

Abstract: A method and associated device for joining a first workpiece to a second workpiece employing a vibration welder includes placing the first and second workpieces in a lapped arrangement and interposing an adhesive material between contiguous surfaces of the first and second workpieces. A first compressive load is applied to a spot welding locus associated with the lapped arrangement of the first and second workpieces, and then relaxed. A second compressive load is applied to the lapped arrangement of the first and second workpieces simultaneous with applying, via a vibration welder, a vibrational excitation to the spot welding locus associated with the lapped arrangement of the first and second workpieces. The applied vibrational excitation is discontinued, and the second compressive load continues to be applied to the spot welding locus associated with the lapped arrangement of the first and second workpieces for a period of time subsequent thereto.

Abstract: The present disclosure relates to a method, to distribute a solder-reinforced adhesive on a first substrate (110), comprising (i) positioning the first substrate (110) to receive an adhesive composite (250) including, an adhesive (200) and a plurality of solder balls (300) on a first contact surface (115) of the first substrate (110), (ii) applying, by a distribution nozzle (205), on the first contact surface (115), the adhesive composite (250), and (iii) distributing, by a conductive spreader (520), the adhesive composite (250). The present disclosure further relates to a method to determine electrical resistance of an solder-reinforced adhesive between a first substrate (110) and a second substrate (120), comprising (i) applying, by a distribution nozzle (205), on a first contact surface (115) of the first substrate (110), an adhesive composite (250) including, an adhesive (200) and a plurality of solder balls (300), (ii) positioning, to a portion of the adhesive composite (250) opposite the first contact surface (115), a second contact surface (125) of the second substrate (120), (iii) attaching, to the first substrate (110) and the second substrate (120), at least one electrical resistance detector (550), and (iv) applying, to the first substrate (110) and the second substrate (120), an electrical current.

Abstract: A device for joining thermoplastic workpieces includes an ultrasonic welder including an ultrasonic transducer, a booster and a horn having a welding tip. A clamping mechanism attaches to the ultrasonic welder and includes an upper frame coupled to a boot. The welding tip of the horn of the ultrasonic welder projects into an aperture in the boot of the clamping mechanism. The clamping mechanism exerts a clamping force on the workpieces that differs from a welding force exerted on the workpieces by the ultrasonic welder when the ultrasonic welder is operating to join the thermoplastic workpieces.
