Numerical Simulation of Resistance Spot Welding of Steel Sheets HCT600X ZF

Nowadays, there are so many reasons behind utilizing high strength steel sheets, more precisely DP dual phase steels in car body production. Car producers tend to choose steel with optimal parameters such as great formability and the capacity to absorb the energy of the collision. HCT600X ZF steel is among the best known and most used high strength materials in car body production. The most used and well known technology for joining high strength steel sheets is precisely the technology of resistance spot welding. RSW Resistance spot welding , is the well known method to join mentioned materials. Simulation programs are utilized to optimize the processes of joining before the joining system is carried out. One of the most popular software for simulating the process of RSW is Simufact Welding. The article deals with parameter optimization of RSW resistance spot welding for hot dip zinc iron coated dual phase steel sheets. The mechanical properties and metallographic observation of joints created by RSW technology on galvanized steel sheets were performed. The result of the simulation of the RSW process was compared with metallographic images after the joining process.
