摘要： An improved cooling system for adapting to a two-component welding electrode device having a shank and cap, includes a retractable nozzle tube, a manifold, and an adjustment element for adjustably interconnecting the tube and manifold. A threaded bushing or plunger is attached to the tube and operable to adjust the distance between the interior surface of the cap and the outlet of the tube to a preferred distance. A threaded sleeve interconnects the tube and bushing for additional adjustability. The tube defines an elastically compressible bellows section, and a spacer is removably attached to the distal end of the tube for automatic adjustment of the outlet position by the cap.

摘要： A blind rivet system including a number of parts to be joined that have aligned holes. A tubular rivet body is disposed in the aligned holes and includes a rivet head portion and a sleeve portion. The head portion and sleeve portion include a longitudinal bore. A mandrel having a head portion greater in diameter than the bore and a shaft portion is disposed within the longitudinal bore. An adhesive is disposed in an annular space defined by the interior surface of the bore and an exterior surface of the shaft portion. An installation tool having a seal intersects with the rivet head portion such that when the head portion is drawn within the bore during installation, the adhesive is maintained within the tubular rivet body and extruded from the annular space to a region between faying surfaces of the parts to be joined.

摘要： Hot cracking in laser welds produced in metal workpieces, especially aluminum or magnesium sheet alloys, is avoided by suitably combining the beams of two different lasers, for example a CO2 laser and a YAG laser, into a compound beam that is moved along a weld path in the surface of the workpiece. The power level of at least one of the lasers is cyclically varied so that weld nugget segments of different alternating, hot crack free, configurations are produced in a linear weld.

摘要： A method of spot welding a sheet overlapped to a tube with a servomotor-driven electrode applying a clamping force to the sheet. Over a first clamping time interval, the clamping force is increased to a first force level, at which point a welding current is applied to weld the sheet and tube together for a welding time interval. The first force level is maintained for a second clamping time interval, after which the clamping force is reduced to a second force level over a third clamping time interval and is maintained for a fourth clamping time interval. The welding current is removed upon expiration of the welding time interval and the clamping force is simultaneously reduced over a fifth clamping time interval, after which the electrode is disengaged from the sheet. The reduction in clamping force during the welding cycle reduces cracking of the spot weld.

摘要： Friction stir fastener equipment and method in which a series of friction stir rivets are rotatably mounted in a supply station and a computer controlled arm terminating in a rotating working head having special gripping jaws that precisely locates and grips a selected rivet. The arm then moves the rotating rivet and progressively drives it into the work until a frictionally heated and plasticized zone of material around the shank of the rivet begins to solidify. The jaws then release the rivet from the drive so that the rivet rotation decelerates to zero. Sufficient hardening of the zone effects the completion of one stir riveting cycle which may be automatically repeated.

摘要： A method of improving weld quality between aluminum members by slowing the rate of solidification of a molten weld trough into solidified material. Upper and lower aluminum members are positioned together in contact between facing surfaces thereof to expose a first outer surface of the upper aluminum member to laser irradiation. A welding laser beam is moved in a path over the first outer surface, wherein the welding laser beam has an energy and width to progressively melt a trough of molten metal to a depth through the upper aluminum member and into the lower aluminum member. The molten metal in the trough has a void filled with gas, and the molten metal re-solidifies into re-solidified metal after the passage of the welding laser beam. An area in and around the trough is heated to slow the rate of solidification of the molten metal into the re-solidified metal, thereby preventing entrainment of the gas within the re-solidified metal.

摘要： A friction stir rivet is rotated and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. A slideable cap contacts the exposed surface of the first workpiece shortly after the process begins. The contact causes the cap to act as a retaining element, limiting the escape of plasticized material from stir site. Once the rivet is driven into the first and second workpieces, rotation ceases and the plasticized material hardens around the rivet. A weld is thus created, joining the workpieces and encompassing the rivet, which provides additional mechanical strength.

摘要： A window washer control system and method administers fluid intermittently to a window based on an intermittent setting. A washer switch includes a plurality of frequency settings for varying a time interval between fluid administering events. The fluid level in a washer fluid reservoir is monitored to ensure a predetermined level. If the fluid level is below a predetermined level, control prevents intermittent washer administration and allows only manual activation.

摘要： The present invention provides a method of joining a sheet metal part to a metal tube to form an assembly. In an overlapping configuration, the parts are held together under a clamping force while a self-piercing rivet is driven through the assembly by a welding electrode. The rivet pierces and passes through the sheet metal part and then through at least substantial portion of the metal tube to thereby form a mechanical interlock. An electrical current is then applied to this mechanical retention to melt a portion of the rivet as well as a portion of the metal surrounding the joining region. The flow of electrical current is then stopped after several welding cycles where the now melted material is allowed to solidify upon cooling, thereby forming a weld.
