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.

Study of the properties of laser welds aluminum alloy grade 5000
Černohous, Filip ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
In working to address the properties of laser welds of aluminum class 5000th These alloys are characterized by low strength and good corrosion resistance. Created a few sample welds on Yb-YAG optical laser, which is subjected to mechanical testing . Procedures are provided in the work of laser technology and welding, as well as general properties and defects in welds. Made welds was evaluated and listed the best welding parameters of the studied process parameters .

Theatre House in Kuřim
Petr, Radovan ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The theme of the master´s theses is to design a wooden structure of city theater with internal steel construction. The concept of wooden structure is developed in two versions according to standard ČSN EN. The theses solve the static effect of the construction and design of individual parts and materials. Theater has dimensions 49.0 x 25.6 m, max. height of 12.5 meters. The construstion is devise to withstand a weight and applicability. The supporting structure of the roof is solved using by 13 arched plate girders. The second variant is designed as arched truss girders. The gable wall is glassed-in, glass envelopes support by wooden structure with columns and side runners. The work also includes solutions for joins and construction details. The structure was solved in the program RSTAB Dlubal 8. The assessment of the components was done using additional module TIMBER Pro. First Variant of plate girder was checking by manual report. The work includes drawings.

Airport Hall
Kulichová, Jana ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
The construction of the concourse is designed from steel.Construction was designed in 2 variants.The construction of the hall is radially curved in plan view with a circular sector on the longitudinal side.Roof structure consists of eight trusses at an axial distance of 9 m.Tracks are arched truss designed as a parallel.Trusses are designed to span 40m.Maximum ground clearance hall at the top is 14 meters.Letištní hala byla řešena v programu Scia Engineer 2014 a součástí je i výkresová dokumentace.

Weldet constructions in technical documentacion
Bartošek, Daniel ; Brandejs, Jan (referee) ; Svoboda, Pavel (advisor)
The presented bachelor´s thesis deals with design documentation of welded con-structions. It provides an overview of weldment design types, basic usage principles and formal prerequisits. The thesis should serve for education of weldment design documentation, for which purpose the set of tasks included in the annex was also created.
