Plasma cutting of high strength steels
Šmak, Martin ; Herčík, Tomáš (referee) ; Kubíček, Jaroslav (advisor)
Cutting of steel is one of the fundamental operations within steel processing and steel product manufacturing. The cutting of high-strength steels represents a significant technological problem since the application of many methods produces an extensive amount of heat that is introduced into the material. The heat may significantly impact the mechanical properties of the steel. The thesis is focused on the application of the method of plasma cutting on high-strength steels. In the theoretical part of the present thesis, the common methods of cutting of steel and the plasma cutting technology are described. The parameters influencing the process of plasma cutting and their impact on the quality of the section are discussed. Furthermore, the concept of a heat-affected zone in the context of the plasma cutting method is concerned. The experimental part deals with the influence of plasma cutting on the hardness of certain types of high-strength steels. Three types of high-strength steels were used for the experiments: ARMOX 500 T, STRENX 650 MC E, and XAR®450. The sections were performed with two different cutting speeds. The size of the heat-affected zone and the hardness in the different areas of the section were evaluated. The results show that the plasma cutting is suitable for cutting of high-strength steels if appropriate parameters are selected. The influence of this method on the mechanical properties of certain high-strength steels is shown and discussed.

Cutting of supporting profiles on building
Protivínský, Pavel ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with technology for material cutting on the building site. Firstly, there were described different methods for material cutting, their principle, reached quality of section, demands for requirements on Occupational safety and health (OSH) and there are described different qualification of device operators. Secondly there were described specific condition in a mobile building site. Eventually, there are compared all the examined technologies after the experiment according to different criteria.
