摘要： A method of welding two or more workpieces employing a motion-controlled electrode that reduces temperature and residual stresses at a workpiece-to-electrode interface is disclosed. During a first period of time, a first electrode force is applied to the workpieces to be welded, and a weld current is applied that causes heating of an associated workpiece-to-workpiece faying surface, the first electrode force being applied at a first electrode stroke. A temperature of the faying surface indicative of a weld nugget formation thereat is determined, and in response thereto the electrode force is reduced to a second level during a second period of time while maintaining a constant electrode stroke. During a third period of time, the electrode force is further reduced to a third level while simultaneously reducing the electrode stroke to a second level. Welding is stopped after the third period of time, resulting in a weld joint having reduced residual stresses and reduced likelihood of stress crack formation.

摘要： In an assembly of facing metal sheets separated by a polymer layer, welded metallurgical bonds are formed between the metal sheets by use of a friction stir weld tool. A rotating tool penetrates the first sheet, locally displaces the encountered portion of polymer film and penetrates into the second sheet. The affected metal of the two sheets is momentarily plasticized and stirred, and the plasticized metal of the two sheets combines to form a weld between the metal sheets. The interposed polymer film may be intended to serve as an adhesive or a vibration damping medium or the like. The facing metal sheets can be layers of facing laminated metal sheet structures that each comprise two metal sheets bonded by an adhesive interlayer.

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： An improved method for joining together the edge portions of first and second panels includes applying a heat curable adhesive along the edge portion of the first panel and then abutting the edge portion of the second panel with the edge portion of the first panel so that the adhesive is interposed between the edge portions of the first and second panels and the adhesive spaces the panels apart and provides a gap between the panels. A brazing material is melted and fills the gap and the heating of the panels by the brazing causes at least partial curing of the adhesive so that the panels are joined together by both brazing and adhesive bonding.

The method includes the steps of: A) forming a hole in at least one of the first metallic member and second metallic member, wherein said hole is sufficiently configured to receive a slug; B) inserting said slug into said hole; and C) passing electrical current through said slug of sufficient intensity to promote melting at the interface between the first metallic member, second metallic member, and said slug, thereby securing the first metallic member with respect to the second metallic member. Alternately, the method may include: D) positioning said slug near said hole; E) passing electrical current through said slug of sufficient intensity to promote arcing between said slug and the bonded metallic structure; and F) inserting said slug into said hole thereby securing the first metallic member with respect to the second metallic member.

摘要： A method is provided for precisely positioning and joining first and second sheet panels. A first hole is extruded in the first panel with an annular upstanding wall surrounding the first hole. The first hole has a diameter to fit closely over the locating pin of a support. A second hole is formed in the second panel and has a diameter to fit closely over the annular upstanding wall of the first panel. A bond is created between the first and second panels adjacent to the annular upstanding wall, so that the annular upstanding wall protects the locating pin from being fouled by the bonding material. The bond may be either an adhesive bond or an electric resistance weld or both an adhesive bond and an electric resistance weld and the annular upstanding wall acts as a dam to protect the locating pin from the adhesive or weld splatter.

摘要： A pair of tubes are provided, one of greater diameter than the other so that the tubes can be telescoped together. An annular inward facing projection is formed on the outer tube for contact with the outside surface of the inner tube when the tubes are telescoped together. An annular outer facing projection is formed on the inner tube for contacting with the inside surface of the outer tube when the tubes are telescoped together. An adhesive is placed on one of the tubes for contacting with the other tube when the tubes are telescoped together. After the tubes are telescoped together weld current is conducted through the tubes to weld the annular projections to the respective opposing tube in contact therewith and at least partially cure the adhesive.

摘要： Methods, program products, and computer systems for estimating a stress of a toughened structural adhesive polymer are provided. One method comprises selecting a strain, a strain rate, a temperature, or a combination thereof at which the stress is to be estimated. A value of a strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the strain-hardening stress is dependent on the temperature and the strain. A value of a non-strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the non-strain-hardening stress is dependent on the strain, the strain rate, and the temperature. The value of the strain-hardening stress is added to the value of the non-strain-hardening stress to obtain an estimated total stress.
