Welding of sub-parts of Kaplan turbine
Keprt, Michal ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Aim of this work is description of design and manufacturing by welding technology of adjustable runner blades circle of Kaplan turbine. For designing and its subsequent strength control using the finite element method were performed with using static analysis in the program SolidWorks ® 2013. Material of adjustable runner blades circle's parts was designed S 355 J2 G3, which is able to withstand a given load. In the design of technology of welding there was elected MAG-welding method, with the active gas mixture Ar +18% CO2. Additive material for welding will be OK Autrod 12.51, like it‘s marked by ESAB s.r.o. For each weld is necessary to create the welding edge, which is made on computer controlled machining machines. In the production we require strict adherence to the prescribed workflow and compliance with WPS protocol. After welding and machining of adjustable runner blades circle we will make weld test, visual examination, dye penetrant and ultrasonic examination.

Welding technology and assembly of bifurcation
Keprt, Michal ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Aim of this work is design and manufacturing welding technology of bifurcation. For structural design and control of static calculation using the finite element method was used SolidWorks ® 2013. Material of bifurcation parts was designed S 355 J2, which is able to withstand a given load. In the design of technology of welding there was elected MAG-welding method, with the active gas mixture Ar +18% CO2. Additive material for welding will be OK Autrod 12.51, like it‘s marked by ESAB s.r.o. For each weld is necessary to create the welding edge, which is made on CNC machining center. In the production we require strict adherence to the prescribed workflow and compliance with WPS protocol. After welding we will make weld test, visual examination, dye penetrant and ultrasonic examination.

Welding head of the longwall shearer
Adam, Karel ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
The aim of this bachelor thesis is to describe the structure and purpose of the longwall shearer drum to descriebe the technological process and to design the technology. Shearer heads are made by welding, MAG method with a protective atmosphere of CORGON 18 (18% CO2 + Ar) was selected. Increasing the strength of the knife holders, made from steel 15 230.3 to 1600MPa and welding to the helical segment of S355J2 + N steel, these clamps cracked cold. An error has been detected by reviewing the entire process and performing calculations. The preheating temperature was too low and was therefore increased to 270 ° C along with the stay for 2 hours at this temperature. Part of the thesis is a sample of the test weld of the rupture holder.

Industrial robot application in area welding technology
Kozubík, Jiří ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This Bachelor’s thesis, which was written during my studies at the Faculty of Mechanical Engineering, Brno University of Technology, investigates Industrial robot application in area welding technology and is divided into three main parts. In the first is the classification and sorting of industrial robots and manipulators according to different criteria explored. The next part concentrates on industrial robots and manipulators used in current industry and informs of the most important industries for industrial robots. The third and final part deals with welding technologies that are used in robot welding applications, presents a survey on compact welding systems including their description and gives us examples of these cells used at present time.
