Material nonlinear static response of civil structures
Kinclová, Radka ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The aim of this bachelor’s thesis is the non-linear elastic and plastic response of the simple beam structures. Also the problematics of the plastic hinges development is adressed. This thesis will then describe the origin and magnitude of the residual stresses caused by welding. Ideal elastic-plastic behavior of materials and elastic behavior with strenghtening will be used to determine the limit load capacity of the simple structures and will be compared to solution in the ANSYS software.

Využití metody svařování v ochranné atmosféře aktivního plynu ve strojírenské praxi
Černý, Oldřich
The aim of this bachelor thesis is joining metals by welding, namely metal active gas welding. The first part is dedicated to different methods of welding in engineering practice and describes the best-known methods and principles in detail. The second part focuses on the selected welding process. It explains the principle of the method, metal transfer from the electrode to the parent material and describes the welding equipment used for this method. The final part deals with filler materials, active gases and parent materials used in practice.

Svařování hliníkových slitin wolframovou elektrodou
Hartman, Tomáš
This thesis focuses on undetachable endless connection by aluminum welding and its alloys by TIG methods. Detailed description of TGI welding method is included in the thesis. The second part deals with a detailed description of aluminum, aluminum alloys, problems that can occur in the process of welding, methods used for creating of undetachable endless connection by welding and conditions for creating of the connection of two parts. Theoretical part of the thesis focuses on comparing of the quality of new links between parts and renovated parts. Links undergo tensile test, metallographic examination, description of defects and evaluation of the quality of the link. The third part of the thesis focuses on safety and possible dangers from welding.

Návrh exteriérového kovového nábytku
Šťastná, Petra
The main goal of this bachelor thesis is to analyse the utilization of metal in the furniture and design own concept of the outdoor metal furniture which is suitable for spaces like parks, bus stops and restaurants with outdoor seating. The work is devided into practical and teoretical part. Theoretical part deals with the history of the metal, development of metal application in the field of furniture. Furthermore, it defines metals suitable for the furniture industry, metal machining, forming, joining and surface treatment. In the second part, there is the realization of own project, development of project from initial sketches to the final realization with regard to the requirements of a particular manufacturer, the Todus company.

Kvalita svarových spojů
Pénz, Attila
The thesis may be divided into two parts, the theoretical and practical part. In the theoretical part of my thesis describe the permanent connection in engineering includes soldering, gluing, riveting and welding and further describe the building-up and weldability tests as part of the technological tests. In the practical part of my thesis describe what and how I was doing. How I progressed in the production of individual samples and testing. We can find there a description of the tensile test, graphical display each tensile test, measured and calculated values and evaluation of tests. Further describe the detection of microstructure and microhardness. Each photo of microstructure I worked to the table and commented what can we see on them. At microhardness we can read about the gist and execution of the test. Obtained values I compiled to the chart and commented. According to the hardness can recognize a structural component and phases. In conclusion is a summary of the measured values and evaluation.
