The production of domestic grill
Blahák, Radek ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
The work deals with the production of domestic grill from discarded storage pressure vessel domestic water of non-alloy steel grade 11 373. The work is divided into theoretical and experimental. The theoretical part is devoted to the study of the manual electrode welding, design appropriate welding parameters and selection of welding electrodes. Further work is focused on graphic design of the grill, under which it will produce grill. The practical part is devoted to verification of appropriate welding parameters for the selected electrode to the control samples, evaluation, and then use the most appropriate type of electrode and the welding parameters for the design of the grill.

Technological process of forging die repair
Kriegsmann, Luděk ; Vaněk, Mojmír (referee) ; Kubíček, Jaroslav (advisor)
The bachelor thesis presents a proposal and solution of renovation of forging insert, which is made of tool steel 1.2367. Due to the literature search, manual electric arc welding with coated electrode was chosen for renovation. The work deals with the stress of the forging insert, which was carried out by strength and thermal analysis. After performance of trial overlay by several coated electrodes, hardness measurement and calculation of dilution of materials was performed. Based on these results, electrode Capilla 66 was selected. Renovation of insert was performed according to preliminary technological process pWPS. The Insert was preheated to 300 °C. As a power source was used TransPocket 3500 and welding current was 190 A.

Welding characteristic of source Omicron Gama 160
Koudela, Michal ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
This bachelor’s thesis deals with the welding properties of the Omicron Gama 160 inverter power supply. The thesis is divided into the theoretical and the experimental parts; the theoretical part deals with the electric arc and the division and description of welding power supplies, especially the Omicron Gama 160. In addition it describes the issues of the selection of suitable electrode and welding parameters and the definitions of the most frequent welding defects including the procedures to prevent them. The second part consists of the experimental verification of the suitable electrode and welding parameters selection. On the basis of the experiment there were elaborated the welding procedure specifications (WPS). The experiment verified that the Omicron Gama 160 power supply is a machine with good price/performance ratio, suitable e. g. for assembly and welding works in a home workshop.
