Vliv formovacích plynů na kvalitu kořenové části homogenních austenitických svarů

Abstract

The goal of this thesis is to evaluate the effects of various forming gases on the corrosion resistance and surface of corrosion resistant austenitic weldements roots. The problematic of austenitic steel welding and their corossion resistance and also the forming gases is explained in the theoretical part. In the practical part the welding of specimens under the protection of various forming gases was carried out at the Temelín nuclear power plant. These specimens were then analysed in order of detecting potentional corrosion attack. This thesis has been constructed in cooperation with the ČEZ group.
