摘要: A rivet configured to provide a strengthened rivet joint capable of acting as a load-bearing joint, such as in a vehicle, is provided. A method of joining a multiple member work-piece utilizing the rivet is also provided. The rivet includes a head portion and an annular body portion extending from the head portion. The body portion has an open end opposite the head portion. The head portion and the annular body portion define an interior cavity that opens at the open end. The annular body portion has an inner surface at the interior cavity and an outer surface opposite the interior cavity. The body portion has passages extending through the body portion from the inner surface to the outer surface, and grooves running along the outer surface intersecting with the passages.

摘要: A fastener is provided for attachment to a workpiece by a friction stir process. The fastener includes a base having an underside adapted to seat upon the workpiece and a fastener portion attached to the top side of the base. An anchor portion projects from the underside of the base and is adapted to be rotated and advanced at high speed and inserted into the workpiece by friction stirring of the workpiece. The anchor portion is embedded in the workpiece upon cooling of the workpiece. The anchor portion has an indent in the surface thereof enabling the softened stirred material to flow into the indent and thereby mechanically capture the anchor portion within the solidified workpiece.

摘要: According to the invention a hollow cylindrical shank of electrically conducting metal is connected to a resistance welder. A coolant supply tube passes through the shank and has an interior coolant supply passage. The coolant supply tube has an outer diameter less than the inner diameter of the hollow cylindrical shank. A weld cap seats on the shank and has a cap tip and a cap skirt that depends from the cap tip and is attached to the shank. An underside of the cap tip faces the shank and the supply tube. A coolant receiving bore formed into the underside of the weld cap extends into the cap tip to receive the coolant supply tube part way into the bore. The bore formed into the underside of the cap tip defines a bore sidewall that provides added area of heat transfer contact between the coolant and the cap tip.

摘要: A friction stir nut is disclosed. The friction stir nut includes a body, a cap, and an anti-rotation feature. The body has an elongated cylindrical shank extending between a first end and a second end, the cap being disposed at the second end, and the anti-rotation feature being disposed at the cap and/or an outer surface of the body. The body and cap have a blind axial hole extending from the first end to the second end, the first end being blind and the second end being open. The outer surface of the first end has a flat surface oriented substantially perpendicular to the axis of the shank, and the body has a cylindrical wall thickness suitable for receiving internal threads. In response to a mandrel tool friction stir welding the friction stir nut to a workpiece and then being extracted, uniform internal threads result at the body. The anti-rotation feature bonds to the workpiece by metallurgical bonding and/or mechanical bonding.

摘要: An improved spot welding tip is adapted for welding a set of adjacent members within a heated zone during a welding program, wherein a quantity of energy is produced, and for reducing the final base temperature of the heated zone. The tip presents a distal engaging surface for contacting one of the members and defines a preferably inner space located a preferred distance from the surface. A phase changing body is releasably retained within the space. At least a portion of the body changes from a first phase to a second phase by absorbing at least a portion of the heat energy during the welding program.

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.
