Welding technology of the "fuel cell" component
Vaculka, Jakub ; Dohnal, Ivo (referee) ; Kubíček, Jaroslav (advisor)
The project aimed at the selection of the optimal welding method for a „fuel cell“ component in terms of the VN-Ú Ltd engineering company. The goal is to compare the methods available in VN-Ú, that is: TIG, MIG/MAG and CMT. It is necessary to analyze the specifics of each of the technologies and the operation conditions which the component will be exposed to. For the comparison of the methods, non-destructive testing of the components, as well as destructive tests of the produced samples have been used. The economic evaluation has been used to compare the costs of different welding methods of the components and to assess the potential investments in CMT device that has only been leased by VN-U so far.

Measurement of roughness of the laser cutting edge
Vaculka, Jakub ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
This bachelor thesis elaborated as a part of branch 2307 engineering studies describes metal laser cutting and its industrial use. The thesis consists of theoretical part and experimental part. The theoretical part describes physical and constructive principle of industrial lasers, its individual types, advantages and use. The experimental part goes into results of common quality steel oxidizing cutting. The CO2 laser from TRUMPF company was used in this experiment. Cut defect appearance and final roughness of cutting edge were the subject of evaluation. The conclusion summarizes effect of material chemical composition and cutting proces parameters on cutting results.
