Resistance spot welding is a very complicated process involving electro-magnetic, thermal, fluid flow, mechanical and metallurgical variables. Since weld nugget area is close and unobservable with experimental means, numerical methods are mainly used to reveal the nugget formation mechanism. So far, heat transfer behaviors in the weld nugget have been systematically studied with traditional ele...

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...
