Virtual commissioning of a robotic welding workplace
Bielik, Ondrej ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This bachelor’s thesis deals with the virtual commissioning of a robotic workplace for arc welding. The resource part was devoted to the issue of virtual operation, management of the robotic workplace and the possibilities of programming industrial robots. The following part is focused on the arc welding technology and knowledge from the field of robotic welding. In the practical part, the welding fixture was conceptually designed, and the configuration of robotic cell was created. For the creation of the welding paths of the robot was used the ABB Robot Studio Program. The results of a comparison of technologies of the robotic and the manual welding show that robotic welding of small series production reduces the time required for product production. In the last part, the production of the welding product as a whole and the possibilities of increasing productivity of robotic workplace were discussed.

Návrh konstrukce přípravku pro svařovacího robota
HAMR, Jan
Robotic welding is currently widely used in the field of Engineering Technology. At the robotic workplaces, welding fixtures are designed for the possibility of clamping, increase of the efficiency and the accuracy of production. The Engel company con-cerns with the conversion from manual welding of weldments to robotic welding. The literature review of this paper describes the robotic welding technology used at Engel. The review focuses on describing the design of the welding fixtures currently in use. Moreover, it focuses on the description of alternative clamping methods. Based on the literature review, three innovative variants of welding fixture design of the specified weldment were proposed for the robotic workstation of the Valk Welding company. Accurate 3D CAD models of the different variants of the welding fixture design with different types of clamping elements were created and and variants were compared.

Welding of the sanitary gully
Skalník, Vít ; Vaněk, Mojmír (referee) ; Kubíček, Jaroslav (advisor)
The aim of this paper is to plan out and realize an optimalization for the welding process of parts of a sanitary gully. Problematics during the welding process of the aforementioned parts together with the usage of welding fixture were explained. On the basis of characteristic signs of welding, an application of other methods was evaluated and the optimal option for the welding process was chosen. During the selection process, hygienic regulations of a non-state funded organization EHEDG (European Hygienic Engineering and Design Group) were taken into account. Furthermore, suggestions for adjustments of the welding process of the forefront of the gully were analyzed. The next step was the realization of the chosen plan and its testing. Part of the process was the implementation of a technological procedure and execution of WPS (Welding Procedure Specification). The end of this paper considers the tecnological-economic contributions of the changed in the procedure.
