MÁCHOVÁ, J. Weldability Evaluation Ferritic Stainless. Ostrava : VŠB – Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Mechanical Technology – 345, 2009, 70 p. Diploma thesis, head Ochodek, V.

Diploma thesis concerns the weldability evaluation ferritic stainless. In the first part of this diploma thesis is accomplished the study of the selected ferritic stainless and their weldability. Next part connects analysis acceptable welding technologies of these steels. Then is designed and realized programme experimental attestation and optimalization of technology welding of sheet metal thickness of 2 mm. It was applied weldability avail oneself of tension tests, heartlessness, microstructure and macrostructure for evaluation. Verification of the selected properties of chosen utility execute with a view to eventual degradation of the material under the ciclic thermal stress in the corrosive environment. Reached results were compared with available scientifically literature and on their bases were effected discussion.
