Title of the thesis:The structure of the resistance spot weld joints combined steel / aluminum
Summary:This thesis is focused on the spot resistance welding of steel / aluminum composite joints. The work consists of theoretical and experimental parts. The theoretical part is divided into five chapters. The issue of welding the galvanized and aluminum sheets, the issue of welding these combined materials and the overview of testing the spot welds is introduced step by step. This thesis presents the optimum welding parameters and applications of this technology in practice. The experimental part of the thesis deals with the optimization of welding parameters of aluminum sheets with a thickness of 1 mm and galvanized steel sheets with a thickness of 0,8 mm. On the selected samples is described the influence of welding parameters on the weld structure.
Key words:weldability of galvanized sheets, Resistance spot welding, galvanized sheets weldability of aluminum
