Animation on the Periphery
Hanáková, Veronika ; Czesany Dvořáková, Tereza (advisor) ; Kubíček, Jiří (referee)
The thesis attempts to precisely describe the production of animation in the context of the state- socialist mode of production. Through the question of "autonomy" for cartoons and puppets films in the era of Kamil Pixa (1969-1985), we will try to specify the position of animation within the re- centralized organization and dramaturgical section in the Short Film. In the context of the normalization period, animation had a different position and function compared to the feature films. Using the example of a studio in Čiklova Street, we outline a model of making a puppet film that was more like a "craft workshop" that retained its notional autonomy as long as it had its own space.
The influence of welding parameters on the quality and mechanical properties of the weld joint
Vlach, Jan ; Stejskal, Ondřej (referee) ; Kubíček, Jaroslav (advisor)
The Master´s thesis focuses on the possibilities of using MAG welding on carbon steel 1.1221(C60E) without using preheating. It researches the effect of basic welding parameters on the final characteristics with the goal being to find a welding seam without defects, without using preheating.
Renovation of wood flaker rotor blades by flux cored wires
Soldán, Jan ; Kubíček, Jaroslav (referee) ; Sigmund, Marián (advisor)
The bachelor thesis presents a state of renovation of wood flaker rotor blades by flux cored arc welding. The theoretical part of the thesis presents posssible ways of renovations with materials included. Subsequently, in order to find out, which one of two flux cored electrodes are more suitable for this specific renovation, the experiment was made. The flux cored electrodes were compared in heat input, price, micro and macro structure and final hardness of welded material. Due to very high hardness results, the flux cored electrode named Megafil A760M was chosen to be used in the renovation. At the end of the thesis, the specification of welding process was according to EN ISO 15 609-1 standard.
Application of WC grains by brazing
Izák, Josef ; Kubíček, Jaroslav (referee) ; Sigmund, Marián (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.
Welding of pipes made of CrMo steel
Matějek, Martin ; Sigmund, Marián (referee) ; Kubíček, Jaroslav (advisor)
The aim of this diploma thesis is to compare mechanical properties of welded joints on tubes from 32x2 mm. Tubes are made from 25CrMo4 steel, which is used for production of racing kart chassis. The steel has a tensile strength of Rm = 800 MPa and up to 1200 MPa after refinement. For welding of samples are used technologies MAG and TIG.
CMT advanced application in industrial practice
Šoulák, Petr ; Sigmund, Marián (referee) ; Kubíček, Jaroslav (advisor)
In presented diploma thesis is studied problematics of welding of high strength steels. This work also describes arc welding in protective atmosphere CMT Advanced. In experimental part of this work is CMT Advanced method compared with conventional arc welding in protective atmosphere in shortcut mode used for welding of Hardox 450 and Weldox 700 E. Comparing of mechanical properties of weld material are realized via transverse tensile testing and measuring of microhardness. Macrostructure and microstructure of weld was evaluated too. In the last part of this thesis is a brief economical assessment of both studied methods.
Optimizing of rotating components production
Kubíček, Jiří ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
The subject of this bachelor thesis is the analysis and following optimalization of technological process of manufacturing the component „Pouzdro“ which is turned on CNC lathe Hardinge Talent 8/52 and milled on Kovosvit MAS MCV 750. The goal of this bachelor thesis is design of production method when will used only CNC lathe DOOSAN PUMA 2100SY, choice of the tools and comparsion of this two methods of the technological processes with regard to production time, lifetime of the tools and economy of production.
Stick welding carbon and high-alloy steels
Hendrych, Marek ; Vaněk, Mojmír (referee) ; Kubíček, Jaroslav (advisor)
This thesis deals with analysis of manual metal arc welding method or method 111. In the research part of this thesis are discused principles of this method, welding power sources and additional welding material-coated elecrodes. Further the thesis is focused on the weldability of steels, especially carbon steels and austenitic stainless steels. In the experimental part was accomplished measurement of operational characteristics of coated electrods. Measurement was carried out on sample of cabon steel S235JR according to ČSN EN and austenitic stainless steel X5CrNi18-10 accordig to ČSN EN. The evaluation envolves a comparison of the results and their justifications.
Comparison of the welding productivity MAG and FCAW
Kutil, Petr ; Sigmund, Marián (referee) ; Kubíček, Jaroslav (advisor)
This thesis is focused on arc welding with MAG and FCAW methods. The first part contains a brief description of these technologies. Emphasis is laid on the principle of arc welding in active shielding gas and on additional materials, especially on solid and flux-cored tubular wires. The second, experimental part, centres on the comparison of MAG (135) and FCAW (136 and 138) methods in terms of the productivity, costs and, last but not least, the quality of fillet welds made in PF welding position. Based on the calculated and measured figures obtained from the experiment, the most suitable method for the given welding position was chosen.
Six Sigma methodology in industry
Kubíček, Jan ; Opočenská, Hana (referee) ; Hammer, Miloš (advisor)
This bachelor’s thesis describes Six Sigma methodology. Six sigma is described generally and includes parts about its history and usage. The most used Six Sigma application cycle DMAIC is introduced together with tools that can be used in its phases. Thesis provides a description of Six Sigma program at Sanmina-SCI Czech Republic s.r.o.
