Studying the effect of mixed shielding gas during laser welding of austenitic stainless steels
 Žemlová, Markéta ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
The diploma thesis deals with problems of laser welding in shielding gases. On the basis of theoretical knowledge in this thesis, was made welding an experiment of 10 samples of steel X5CrNi18-10 in two different shielding gases. Flow of shielding gases has been shown by schlieren method. On the samples of welding joints have been made mechanical tests (tensile test and hardness test). Welded joints were metallography evaluated and structure of them was confirmed by measurements on ferrite meter.
