Abstract

Master thesis is dealing with welding method of the Impeller. The theoretical part is based on study of weldability of martensitic chromium steels, including design of appropriate methods for welding Impeller. Suitable filler materials have been designed on the basis of chosen welding methods and basic materials. In the experimental part was carried out weldability verification of martensitic chromium steel for several samples by testing the hardness, microhardness and metallographic analysis. The measured data were processed into tables, graphs and pictures. Based on the results the welding technology has been optimized.
