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： The present invention provides a method of joining dissimilar materials, particularly a non-ferrous component to a ferrous component 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 non-ferrous component and then at least into contact with the ferrous component 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 ferrous metal in 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.
摘要翻译：本发明提供了将异种材料，特别是有色金属组分连接到含铁组分以形成组件的方法。在重叠构造中，部件在夹紧力下保持在一起，同时通过焊接电极将自穿孔铆钉驱动通过组件。铆钉刺穿并穿过有色金属部件，然后至少与含铁部件接触，从而形成机械互锁。然后将电流施加到该机械保持件以熔化铆接部分以及在接合区域中的一部分黑色金属。然后在几个焊接循环之后停止电流，其中现在熔化的材料在冷却时固化，从而形成焊缝。

摘要： A sheet metal assembly includes first and second metal sheets having flanges extending from the sheets. The flanges overlap and are in engaged parallel facing relation for a width between outer edges and flanges. At least one pair of self-piercing rivets joins the flanges at spaced locations along the width. The rivets each have a head and a shank extending into the flanges from opposite sides. The rivet heads of each pair are located in opposite flanges and are spaced further from the outer edges of their respective flanges (nearer the load-application ends) than are the shank portions of other rivets of the pair.

摘要： A method for monitoring and controlling a vibration welding system includes collecting sensory data during formation of a welded joint using sensors positioned with respect to welding interfaces of a work piece. A host machine extracts a feature set from a welding signature collectively defined by the sensory data, compares and correlates the feature set with validated information in a library, and executes a control action(s) when the present feature set insufficiently matches the information. A welding system includes a sonotrode, sensors, and the host machine. The host machine is configured to execute the method noted above.

摘要： A optical system and method of measuring a strain on a surface of a band of a sheet of a material. A single line, or an area having a boundary line, is marked on the band before deformation. The line traverses a width of the band at angle. The band is deformed and an equivalent two-dimensional image of the line after deformation is obtained. The line before deformation is compared with the two-dimensional equivalent image of the line after deformation, and the strain on the surface of the band after deformation is determined.
