摘要： A method is provided for attaching a fastener to the inside wall of a member. The fastener may be a bolt or a nut having a shank and a shaped head with head portions radiating from the shank. A hole is made in the member and has a shape closely corresponding to the shape of the head. The head of the fastener is inserted into the shaped hole and the fastener is reoriented so that the head engages with the inside walls of the member and therefore the fastener cannot be withdrawn. Electric current is applied to the fastener and the member to bond the head to the inside wall of the member either by heat curing an adhesive coating the head or by creating an electric resistance projection weld between the fastener head and the member.

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： 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： 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 improving a single-sided resistance spot weld includes forming an adhesive bond between a sheet and a tube to thereby form a two-ply structure by which the sheet metal and the tube wall stiffen each other against bending. The adhesive bond is preferably formed by heat curable adhesive and the adhesive is partially cured by applying the electrode to a spot on the sheet and then conducting current through the electrode to induce electric resistance heating in the sheet and tube to cure the adhesive. After the adhesive bond is formed, the electrode is moved to a new spot on the sheet and then forcibly applied against the stiffened sheet and resistance welding current is applied through the electrode to form a resistance spot weld between the stiffened sheet and the stiffened tube wall.
