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： This invention provides a method of joining overlapping galvanized steel parts using two lasers for in tandem slot cutting and welding. A first laser beam impacts the steel parts at an energy level sufficient to cut a slot at least through the facing steel part to provide a path for vaporized zinc to escape from a welding interface. Immediately after the first laser beam passes, a second laser beam is directed along the slot at an energy level sufficient to melt ferrous material to fill the slot. After the second laser beams passes, the molten metal is cooled by the surrounding unheated metal to solidify and form a weld nugget.
