Laser welding of steels in automotiv industry

In the automotive industry is beginning to replace the resistance spot welding by laser welding. The bachelor thesis was an analysis of laser welding methods, especially the method of remote welding, which is used for the experiment. Furthermore, the use of laser welding was described. We have also suggested the general technological process of welding. The experimental part was carried by metalografic cut of welded sample, which was evaluated by its macrostructure and microstructure
