Production process optimization
Habásko, Jakub ; Koška, Petr (referee) ; Fiala, Alois (advisor)
HABÁSKO Jakub: Production process optimization. The Master´s thesis of Master degree, second grade, school year 2008/2009, FME Brno University of Technology, Institute of Metrology and Quality Assurance Testing, October 2009, pages 68, pictures 40, tables 2, supplements 4. The project elaborated in frame of the Master degree, study branch Metrology and Quality Assurance Testing. This Master´s thesis deals with optimization of process plan. In virtue of submission was created an analysis present condition using of statistical methods and it was created suitable statistical methods applicable in production organization. Then is here described the problem of brazing bells, because in this place is originating the most of uptightness. Then the thesis brings recommendation and findings, which can help with optimization this process.

Laser brazing in the car industry
Podstavek, Michal ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated in frame of engineering studies of the subject M-STG Mechanical Engineering describes elementary methods of joining in the automotive industry. Moreover, it inquires into optimization of laser brazing on the back cover ŠKODA Superb. During the optimization of the process six samples were designed, and the adjustment of the brazing parameters were performed. Consequently, the samples were evaluated by tensile and metallographic tests. Finally, EDS analysis was performed and visual assessment as well.

Analysis of Influence of Manufacturing Technology on Utility Properties of a Reducing Valve Part
Novotný, Michal ; Sigmund, Marian (referee) ; Řiháček, Jan (advisor)
The present work is focused on the comparison of the currently used technology for the production of reducing resistors, i.e. electroerosive machining in combination with soldering on one side and the use of a suitable additive technology on the other hand. In addition to the purely technological aspects, such as the individual production processes or their preparation, economic aspects are also compared, supplemented by an assessment of the delivery times of the finished parts. The analysis is carried out The environmental impact of both production approaches is also analysed. The individual comparisons form the basis for to assess whether the replacement of the conventional manufacturing approach by additive manufacturing is advantageous in this case. The results of this assessment can then be used for future applications of the considered additive manufacturing approaches for similar components.

The options of the joining of tube components
Holusek, Maxmilián ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The bachelor thesis deals with tube components joining methods. In the thesis, the preparation of the tube components is mentioned, as well as its tools and machines for cutting and adjusting the components. Furthermore, the work introduces several joining methods such as soldering and brazing, welding, pressing technology, adhesive bonding and threaded connection. The basic principle is described for each method, as well as using tools and machines plus advantages and disadvantages. In the end, the use of tube components is presented.

Application of WC grains by brazing
Izák, Josef ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
Bachelor thesis is aimed to assessment condition of brazing component barking plate. Solder contains grains of tungsten carbide is applied on steel due to raise hardness of plate. Applied solder with grains, does not only raise the hardness, but also multiply increase lifetime of plate. Technology, which is used to brazing, is oxy – acetylene flame. It will be examined two type of solder. In the first it is provided optical exam and then destruction exams (micro hardness, macrostructure, microstructure, SEM and EDS analysis). In the end It was proposed qualifications of brazer and exams of brazing join.

Usage of Solders with Higher Melting Point for Hybrid Integrated Circuits
Janda, Ondřej ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
Bachelor thesis introduces the problematics of soldering, explains basic phenomena and principles affecting brazing and points out their positive and negative outcomes, as well as trying to suggest solutions to those negative symptoms accompanying the brazing. Practical part describes a design procedure of the test substrates, methodology of mechanical tests and optimalization of brazing process. As a part of the research, a design and construction of a various brazing tools with heat transfer through a conduit, is included.
