Comparison of manual laser and TIG welding
Černý, Jan ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
The diploma thesis deals with the comparison of TIG welding methods (141) and unconventional methods of manual laser welding (51) of thin sheets of stainless steel X5CrNi 18-10. The goal of the thesis is to determine the difference in quality between the selected methods on the welds made and to develop a technical and economic evaluation. At the beginning of the diploma thesis, a literary study is analyzed with a focus on the principle of individual welding methods, possible defects arising during welding and the weldability of individual types of stainless steels. In the experimental part, the design of the experiment is discussed, which consisted in welding samples of selected weld joints using individual technologies. The welds were then evaluated using non-destructive and destructive tests. Finally, the economic evaluation of both technologies and the return of the equipment were also calculated.

Metal welding and weld testing according to new norms ISO, EN and consequential ČSN
HAJNÝ, Tomáš
Work considers kind of materials joining via welding. At the begining the bachelor work considers history of this branch. Then there are norms and regulations ISO, EN and CSN for welding. Next part describes welding methods and weld tests. The last part is focused on common technology of welding. Ambition of this bachelor work is to create learning text and briefly show to the students, which are the methods and kinds of welding and welding tests and possibility how to use this methods in practice. Here are methods described theoretically and also examples from practice. This bachelor work can be used at pedaggical faculty for teaching this topic.
