Abstract
The bachelor thesis deals with the development of structure and mechanical properties
of the pressure welded and bent tubes for the automotive industry. The theoretical part focuses
on the processes that take place during the forming of tubes. The practical part of the thesis
aims for the development of microstructure and macrostructure during metal sheet forming,
welding, annealing, drawing, and subsequent quenching with tempering. The practical part
emphasizes the tensile tests and hardness profiles of the material.
