摘要： A method of joining a multiple member work-piece includes stacking the members of the work-piece on a die such that a first of the members rests on the die. Next, a rivet is driven into the second member until the rivet penetrates the members and deforms. The rivet is then welded to the first member to strengthen the riveted joint. Different mechanisms may be used to accomplish the welding. For example, a laser beam may be directed through a passage in the first die to target the area of the riveted joint to be welded. Alternatively, the die set, rivet, and first member may be arranged to form an electrical circuit that welds the joint via resistance heating. An assembly of a multiple member work-piece and a rivet made according to the method is also provided.

摘要： A closure panel assembly includes an inner and an outer panel, the inner panel having a crimped edge surface feature and a textured surface feature such as a set of radial projections or asperities. Adhesive material is applied between the panels, and the outer panel is hemmed and adhesively bonded to the inner panel. The surface features affix the panels together without induction or intermediate heat curing of the adhesive material. The outer panel has a hemmed edge enclosing the crimped surface feature, with the adhesive material positioned therebetween to form a seal of a relatively low shrinkage rate. A method of forming the closure panel assembly includes forming a first and second surface feature on the inner panel, such as by using swaging and coining, respectively, applying adhesive material therebetween, and hemming the panels to form a hem seam.

摘要： A method is provided for monitoring and controlling the process consistency of an arc welding process. The weld voltage signal is monitored and analyzed to determine the occurrence of the detachment of a weld droplet. The weld droplet detachment is determined via statistical techniques as having occurred at a normal interval following a prior detachment indicating consistent weld process or as a sporadic detachment having occurred at an irregular interval with respect to the prior detachment and indicating inconsistent weld process. The weld process is adjusted by controlling the weld process variables to maximize the predominance of droplet detachment at normal intervals and minimize the occurrence of the sporadic detachments.

摘要： A closure assembly with a shape memory polymer seal is provided for use with a vehicle. The closure assembly includes a frame member configured for attachment to the vehicle body to selectively transition from a closed position to an open position. The seal structure includes a base portion elongated along and attached to a peripheral edge of the frame member or the vehicle body, and a flexible contact portion extending integrally from the base portion and configured for sealing communication with an opposing surface. A thermally-activated smart material (TASM), namely a shape memory polymer member, is disposed inside a cavity within the contact portion. A thermoelectric device is in thermal communication with the TASM, and is characterized by a thermal differential when current flows therethrough. The TASM is activated in response to the thermal differential of the thermoelectric device, thereby altering at least one physical property of the TASM.

摘要： A fastener is provided for projection resistance welding to a panel. The fastener includes a base having a fastening element, such as a threaded stud or a nut integral therewith. Multiple projections formed integral with the base extend therefrom to engage with the panel to be welded to the panel by electric resistance welding. A groove is provided in the base facing the panel and is filled with a heat activated expandable sealer material. Upon heating of the base during the electric resistance welding, or in an oven, the sealer expands to fill and seal any gap between the base and the panel.

摘要： A method for testing adhesive bond quality includes subjecting an adhesively-bonded workpiece to a known loading function. The loading function may be cyclic, linear, or nonlinear, and configured not to damage the workpiece. Response characteristics of the workpiece are measured during the loading. Measured response characteristics are compared with baseline or nominal characteristics and the adhesive bond quality is determined from the resulting comparison. A differential signal may be generated based upon the comparison of measured response and baseline characteristics and used to determine the adhesive bond quality, possibly with an algorithm. Being within the acceptable range is indicative of acceptable adhesive bond quality. The root cause of failure may be determined and a course of action based thereupon; including: localized curing, inspection, repair, and destruction. Following corrective courses of action, the workpiece may be re-tested and compared again to the baseline.

摘要： A sheet metal assembly includes first and second resistance weldable metal sheets having flanges extending from the sheets. The flanges overlap in parallel for a dimension. A resistance weldable metal shim is disposed between the flanges and extends to the outer edges thereof. A weld joins the metal sheets through the shim. The shim increases the mechanical strength of the assembly. The increase in mechanical strength from the shim allows for reductions to the flange width. As a result, a lighter assembly of equivalent strength is produced.
