Localization of reinforcement in elements of reinforced concrete structure
Fusek, Aleš ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This bachelor thesis deals with the search for non-destructive methods of reinforcement in concrete structures using electromagnetic indicators. The theoretical part describes the methods of diagnosis reinforcement capabilities and limitations of the methods of electromagnetic indicators and comparisons with other methods. Furthermore, a overview of the reinforcement used in the 60s of the last century. The practical part describes the measurement on reinforced concrete construction hall and compares it with the measurement obtained on the models in the laboratory at the focus of the sensitivity of measurements and data processing.

Optimization of manufacturing of iron castings to reduce the quantity of defects
Blaha, Marek ; Brázda, Zdeněk (referee) ; Juliš, Martin (advisor)
The presented diploma thesis is focused on defects of castings as well as optimization of production with the aim of reducing the number of defective products. The theoretical part is focused on basic information about cast iron and its production, structure and mechanical properties. Another part of this thesis describes the defects of castings and options for non-destructive testing of cast iron castings. In the experimental part are analyzed three sorts of defective casting. Castings for testing were provided by JMA s.r.o. foundry. The summary contains tests results and proposals for optimization of production.

Diagnostics and assessment of the bridge structure
Fadrný, Michal ; Heřmánková, Věra (referee) ; Kocáb, Dalibor (advisor)
This diploma thesis targets on diagnostics and assessment of bridge structure Most Kaštanová přes Svitavu, reg. number 380-001. Concrete material characteristics have been assessed in laboratory, after visual inspection, diagnostical testing and sample core drilling were made. Findings from laboratory tests are summarized in the conclusion of the thesis. It focuses on an evaluation of current bridge condition and presents various options that will help polong lifetime of the bridge.

Preliminary survey and assessment the building before renovation
Bartoň, Vojtěch ; Stehlík, Michal (referee) ; Cikrle, Petr (advisor)
This bachelor thesis deals with the construction and technical survey of a masonry building with cast iron columns. Construction-technical survey was carried out, due to the planned conversion of the building into a apartment building with public services. The thesis contains description of construction and technological survey and diagnostic methods, which includes evaluation of essential characteristics of masonry structures and cast iron columns. The practical part contains processing of diagnostic survey. Its result is determination of material and geometric characteristics of the structure.

Survey and assessment of reinforced concrete bridge construction
Šnédar, Jaroslav ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
The aim of this thesis is to evaluate the real condition of reinforced concrete beam bridge located in Brno Jundrov. In order to evaluate this condition, there was made the main bridge inspection. Subsequently, a number of diagnostic methods were used, such as hardness tests, concrete stress strenght, ultrasonic pulse method, including their evaluation. In terms of the main inspection, the condition of construction of the bridge was evaluated as V - bad. We found out that the concrete from which the bridge is built of is in very good condition. The problem, however, is the condition of the reinforcement located on the bridge. Based on its condition there must be expected lifespan within the next 5-10 years.

Locating welds defects on cranes.
Zíka, Luboš ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
The diploma thesis deals with the problematics of weld defects of cranes localisation and check. The aim is to analyse non-destructive methods, monitor the occurence of defects and their form and also to suggest the procedure of correction. The work is divided into a theoretical and practical part. In the theoretical part, there is an analysis of individual methods of non-destructive testing that are used for weld check on a particular girder. There is also an analysis of welding technologies used when making a crane girder. The practical part deals with evaluation of weld defects using two methods of non-destructive testing. Furthermore, statistics of defects is realised. In conclusion, the statistics outcome is resumed and evaluated.

Analysis of technology for checking the tightness of manufactured heat exchangers with a focus on increasing its reliability
Grúz, Jan ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This master thesis deals with the analysis of the leakage checking technology of heat exchangers in a selected industrial company. According to this analysis the specific improvement proposals with the potential to increase the reliability of this technology are identified, selected and created. This analysis is carried out through consultations and meetings with the employees of the company and also with the help of the provided data and information. On the basis of this analysis, the technical background research of the leak testing technology and the DMAIC methodology, specific modifications with the potential to improve the operated technology are proposed and the amount of investment to implement them is estimated.

Non-destructive testing of welds
Potanko, Andrej ; Kudělka, Vladimír (referee) ; Sigmund, Marian (advisor)
The diploma thesis deals with the analysis of non-destructive testing methods intended for the control of welded joints. It discusses the scope of NDT tests for pressure piping according to the current European Union directive. In the next part, the work deals with the construction of a welded joint intended for pressure piping. In the practical part two stainless steel tubes were welded by TIG method. In the TIG method, the thesis deals with its principle of operation, advantages, disadvantages and its application. Subsequently, a visual, penetrating and radiological test was carried out on the weld. As a result of these tests, the weld is satisfactory.

Modern diagnostic methods use in defectoscopy
Vítámvás, Zdeněk ; Stránský, Lubomír (referee) ; Juliš, Martin (advisor)
Nowadays non-destructive testing offers various ways to detection defects in material. By selecting of suitable method or suitable combination of tests we can locate the defect and determine size of defect with sufficient accuracy. For higher probability of detect defects and for easier operation and evaluation are still evolve new ways of inspection. There are summarizes both ordinarily and modern methods using in defectoscopy in this work. There are describe its principles, courses of testing, suitability of use and there are drop next general information.
