Non-destructive testing of welds
Šaloun, Jan ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
This thesis describes non-destructive testing (NDT) of fusion welds of metals. There are five fundament methods of NDT discussed in the theoretical part – visual and magnetic particle inspection, ultrasonic, radiography and penetrant testing. Principles of methods, examining procedures and their evaluations are described. The methods are compared with each other. In the experimental part of the thesis two samples of welding joints were welded and tested by selected methods. To verify correctness of the indicated defects, metallographic samples were made. At the conclusion practical results are compared with theoretical statements.

The roof structure of a bus station with facilities in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of bachelor's thesis is design and assessment of steel load-bearing construction of bus station in Vrchlabí. It is designed as a co-operating load-bearing steel pillar based structure with the construction of the outdoor platform. The design was considered in four different options for inner building. Followed was mainly the weight of inner structure with respect to the roof deck. The selected option is then incorporated into the scope of the entire structure. Design and assessment was conducted in accordance with the applicable standards and by using a computer program Scia Engineer.
