Manual versus orbital GTAW piping welding
Hofbauer, Jan ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
In thesis are compared options of stainless steel piping welding, orbital and manual version of method GTAW and GMAW. At the beginning, these methods are described theoretically and after that there are described materials used for fabrication two test welds on austenitic steel piping of diameter 168 mm. The first weld was made by orbital method GTAW, the second one by manual method GMAW. Next, these two welds are compared based on defects, welding parameters and width of heat affected area. The conclusion is that both welds are defect-free and because of economical aspects is better to use orbital GMAW method for this diameter of piping.

Loss of strength during welding aluminous alloys AW 6060
Sklenář, Martin ; Vaněk, Mojmír (referee) ; Sigmund, Marian (advisor)
The aim of the bachelor thesis is to qualify the welding procedure according to the standard ČSN EN ISO 15614-2. At the beginning of the work is introduced a company with which was this thesis made. This is followed by an assessment of the issue of aluminum. Furthermore, the mechanical properties of aluminum are discussed. Follows by part about welding specially about aluminium welding. In the practical part the samples were welded and subsequently evaluated, then the design and qualification of the welding process was made. In conclusion, the possibilities and results that have been achieved are summarized.
