Design of cutting device for precise cutting of aluminum alloy tubes
Schaffelhofer, Igor ; Omes, Jiří (referee) ; Tůma, Jiří (advisor)
This master thesis is focused on the design of device for precise cutting of aluminum alloy pipes, which are part of gas-insulated switchgears at Hitachi Energy. Due to the implementation of new welding technology using friction stiring, there are increased requirements for the quality and accuracy of cuts, and the overall acceleration of the cutting process, including the associated handling. The current situation is the division of aluminum pipes using a band saw, which is insufficient not only in terms of output quality but also capacity. The proposed solution in this master thesis is in accordance with the necessary quality and capacity input requirements, which is required by friction stir welding technology (FSW). In the introductory research part, the work is focused on methods of material cutting. In the next part, the requirements for the cutting device are evaluated together with the evaluation and selection of a suitable method for the design. In the structural part of the master thesis, the individual concepts of partial parts are given, where the selected variants are supplemented by appropriate calculations.

Design of clamping device for tubular conductors
Schaffelhofer, Igor ; Tůma, Jiří (referee) ; Tůma, Zdeněk (advisor)
This bachelor thesis is focused on design of clamping device, which is a part of welding positioners for welding of aluminum tube conductors in ABB company. In the theoretical part, there are individual requirements of clamping devices with examples of their applications. The practical part is focused on the design of individual parts that meet the requirements for tube conductors and the functionality of the clamping system for arc welding of alluminium alloys.
