    Abstract: A vibration welding system for joining a wire to a substrate includes a welding pad attached to a sonotrode and an anvil. The welding pad includes first energy directors that are disposed in a first region and second energy directors that are disposed in a second region. A channel is formed between the substrate and the first energy directors when the second energy directors are in contact with the substrate. The channel is configured to accommodate a portion of the wire, and has a depth that is less than a cross-sectional diameter of the wire. The wire and the substrate are clamped between the welding pad and the anvil during operation of the sonotrode. The first energy directors urge the wire towards the substrate during the operation of the sonotrode to effect joining of the wire to the substrate.

    Abstract: A method for manufacturing a battery cell having electrode foils protruding from a cell pouch includes positioning the cell pouch in a fixture such that distal end sections of the foils extend outward from the fixture. The method includes clamping the distal end sections in a curvilinear guide clamp to cause the distal end sections to taper into an electrode foil stack, and then translating the clamp a predetermined distance toward the fixture to displace the distal end sections by the predetermined distance. The method also includes trimming the distal end sections using a trim tool, positioning a sonotrode and an anvil adjacent opposite surfaces of the stack, and ultrasonically welding the stack to a conductive lead tab using the sonotrode to thereby form a welded joint within the battery cell. The sonotrode may be multi-sided with different knurl patterns for performing different welding processes.

    Abstract: A method and fixture for welding a battery foil-tab assembly is disclosed. The fixture includes a first clamp member having a first clamping surface defining an opening extending into the first clamp member and a second clamp member having a protrusion surrounding a weld slot. The opening of the first clamp member is configured to receive a portion of the protrusion with the battery foil-tab assembly disposed therebetween. The second clamp member is moveable toward the first clamp member to align the weld slot of the second clamp member with the opening of the first clamp member, thereby causing the protrusion to cooperate with the opening of the first clamp to deflect a portion of the battery foil-tab assembly out of a plane parallel with the battery foil-tab assembly. A laser beam is directed at the out of plane portion to laser weld the battery foil-tab assembly.

    Abstract: A lap belt pretensioner for a lap belt configured to secure an occupant of a vehicle seat includes a pyrotechnic device. The pyrotechnic device is configured to generate a force directed to tension the lap belt around the occupant and emit an exhaust gas including particulates at high pressure and high temperature as a byproduct of the generated force. The lap belt pretensioner also includes a housing configured to retain the pyrotechnic device and defining an exhaust passage configured to expel the exhaust gas from the lap belt pretensioner. The lap belt pretensioner additionally includes a shield arranged over the exhaust passage and configured to collect and/or deflect the emitted particulates and dissipate heat energy thereof. A vehicle having the vehicle seat mounted to the vehicle structure and employing the seatbelt system is also provided.

    Abstract: A system for joining at least two components by welding includes a magnetic base for receiving the components for welding and a flexible magnetic member configurable to correspond to a weld path defining a weld joining the components. The flexible magnetic member exerts a retention force on the components in response to a magnetic field produced by selective activation of the magnetic base. The system can include a magnetic locating element positioned adjacent a perimeter edge of the component to be welded, for generating a repulsive magnetic force between the flexible magnetic member and the magnetic locating element to locate the flexible magnetic member relative to the perimeter edge and provide clearance for a welding device to access a continuous weld path defined by the perimeter edge, such that the welding device can form a continuous weld along the weld path. A welding method using the system is provided.

    Abstract: An apparatus for in-situ monitoring of a workpiece includes a fluidic container defining a cavity and having a peripheral portion that defines an aperture. The fluidic container contains an acoustic transmission fluid. A conformable membrane is sealably disposed about the peripheral portion of the aperture of the fluidic container. The conformable membrane is disposed to sealably contain the acoustic transmission fluid within the fluidic container and to conform to a surface of a portion of the workpiece absent an interposed fluid. An acoustic source transducer is disposed in the cavity of the fluidic container and in contact with the acoustic transmission fluid. The acoustic source transducer is disposed to generate a first acoustic wave in the direction of the workpiece. An acoustic receiving transducer is disposed to monitor a residual acoustic wave that is reflected from the workpiece in response to the first acoustic wave.
