This paper presents a review of various interlayers employed to enhance the properties similar and dissimilar materials welded by resistance spot welding (RSW). The commonly used base are steel, Al alloys/steel, Al/Al alloys, Al/Ti Al/Mg etc., proposed researchers include Zn, Ni, Sn, galvanised SS304, Al–Mg, AlSi12, graphene, carbon nanotube, etc. Microstructural changes due incorporation were ...

China recently surpassed Japan as the world's second largest automobile market after the United States. Annual output of automobiles is close to six million units a year. A key tool in automotive production is the spot welding gun and the industrial robot. One of the most important parameters of a spot welding gun is force tolerance. ABB is helping the Chinese automotive industry improve weldin...

The paper deals with the analysis of influence parameters resistance spot welding. Resistance welding is high-efficiency process for joining metallic materials. application still most used method car body parts. was determined by an experiment. optimal achieving highest load-bearing capacity joints material TRIP40 / 70 a defined thickness 0.77 mm were determined. results reached values from 630...

In this work, the process of dissimilar resistance spot welding (RSW) for AISI 304 and 1060 steel sheets is experimentally investigated. The effects main parameters such as current, electrode force, cycle, cooling cycle on tensile-shear strength (TSS) RSW joints are studied. To aim, using a central composite experimental design based response surface methodology (RSM), tests were performed. Fur...

According to structural characteristics of the parts for the power battery, a structural model of clamp welding head basing on the loop sensor principle is established by means of PRO/E in this article, and a newly power battery spot-welding maching was research. It had some functions of the data’s input and modification, controlling of welding worktable, spot-welding mechanism adjusting initia...
