Design and Simulation of Spot Welding Process

The presented work confirmed that the use of resistance spot welding process in industry can be considered as one of the widely processes applied for sheet joining purposes. Finite element modelling technique is an efficient tool which can be effectively and efficiently applied to describe the welding process. The effect of electrode geometry on current distribution has been investigated. A model of thermo-mechanical- electrical coupling with two dimensional axisymmetric is created to explain the process of weld. The modelling is completed to run the electrode lifetime and present distribution in the electrode face. Both thermal-electrical and mechanical evaluation is made to create version. During simulation, background of temperature and procedure distributions had been called. Development of weld nugget through procedure and impact of process parameters on nugget formation have been researched. Good agreement of uniform current distribution is extracted from the computational investigation, which allows including the benefits of design and simulation of processing weld related to production performance and cost.
