Muroň Tomáš. Welding of Deep-Drawn Steels After SPD Treatment. Ostrava, 2026, Bachelor´s Thesis. Ostrava: VSB – Technical university of Ostrava, Faculty of Mechanical Engineering, Department of 345., Thesis supervisor: Ing. Vladislav Ochodek, Ph.D. This bachelor's thesis deals with the welding of deep-drawing steels processed by SPD (Severe Plastic Deformation) technology. The introductory part characterizes both base materials, DC01 and DC03. Subsequently, the technology used for processing the specified steels is described, which is based on the principle of severe plastic deformation. Furthermore, a study is conducted on suitable welding technologies for the given material, and a procedure for evaluating the steel strips after the SPD processing is proposed. For the selected material and technology, a test welded joint is designed, followed by an inspection of selected properties and an evaluation of the test joint results. Finally, all findings are analyzed, and a discussion of the achieved results is provided.
