Influence of the Joining Force on the Nugget Diameter During Resistance Spot Welding of Aluminum Materials

Abstract Ever new requirements for the environmental compatibility and safety of products do not stop at automotive industry. This results in ever shorter time windows pre-series processes. For this reason, time-consuming preliminary tests must be minimized to ensure an accelerated start-up production that is as trouble-free possible. maxim applies all parts automobile, but especially body shop, where just-in-time has been norm years any downtimes are particularly severe. In order meet these requirements, it advantageous understand or predict result a process well paper deals with resistance spot welding aluminum aims generate knowledge about relationship between setting parameters target value. Since large number comprehensive investigation would go beyond scope study, focus on joining force features generated from it. The parameter nugget diameter points. data determined experimentally evaluated help Machine Learning (ML) approaches. correlations presented graphical form. quantification influence expected lead reduction thus gain time.
