New aspects of MIG/MAG welding
Týn, Zbyněk ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This bachelor thesis is focused on the latest welding technology MIG / MAG. Between which such us method of Cold Metal Transfer or Advanced CMT. These new techniques are mainly used for welding thin sheets. They integrate gradually into the connecting of various types materials and also bulky welded structures. All of this is demonstrated thanks to the management and control of the welding process.

Possibilities of heat transfer regulation while MIG/MAG welding
Mášová, Pavla ; Hála, Michal (referee) ; Daněk, Ladislav (advisor)
The project is elaborated in terms of bachelor's studies of branch 2307. The project is submitting possibilities of heat transfer regulation while MIG/MAG welding. Energy storage welding is a conventional method of heat regulation. Other methods were developed by company producing welding unit. A company Kemppi offers a method Fast Root for the heat regulation, methods Rapid Arc and Rapid Melt were developed by AGA AB and company Lincoln Electric offers a method Surface Tension Transfer. Method Cold Metal Transfer by Fronius company and ColdArc by EWM company are used for reduction of heat transfer into the weld steel-aluminium.

3D metal printing by wire welding methods
Přibyla, Dalibor ; Izák, Josef (referee) ; Sigmund, Marian (advisor)
This thesis presents the most commonly used technologies of 3D metal printing by wire welding methods, like WLAM, EBAM and WAAM. Deals with their principles, sub methods, applications, suppliers and also with current researches and trends, which are focused on deposition of thin layers. CMT technology is closely described, with attention on its certain kinds, like Cycle step, Advanced, Pulse Advanced, Pin and Braze+. Then, the CMT workplace at IMID DREAD, FME BUT is described by individual components, automatization and robotization. Final evaluation shows, that the chosen workplace is appropriate for required 3D print of magnesium alloys and overhanging structures, due to cold metal transfer technology and low purchase price.

3D metal printing by robot
Tvrdoň, Radek ; Mrňa, Libor (referee) ; Sigmund, Marian (advisor)
The diploma thesis presents an overview of additive production technologies and a summary of technologies used for 3D metal printing using a robot. All of them are generally described and at the same time assigned to their specific commercial use, or the academic research that deals with them. The work examines the suitability of the material EN ISO 14341-A: G 3Si1 for 3D printing, for which a modification of the Col Metal Transfer technology, Cycle Step is used. The experimental printout of the sample is evaluated on the basis of surface and mechanical tests. Capillary test, examination of microstructure a macrostructure, tensile test and microhardness test. All of them were satisfactory and the suitability of the welding wire for 3D printing was confirmed by the given technology.
