Optimization of manufacturing process of tubes
Kohout, Jaroslav ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
Elaborated thesis presents a proposal to increase welding speed in the process of production of stainless steel tubes 1.4301 and 1.4404. Based on analysis of the existing method was evaluated, that performance improvement would be most appropriate by adjusting the welding technology. Four methods have been proposed, describing the principle, andvantages and disadvantages. The most effective and cheapest was the modification of the existing TIG method using two torches, with the possible improvement of using another shielding gas.
Využití tavného svařování pro výrobu nízkotlakých nádob
Barták, Jan
The bachelor thesis deals with the issue of fusion welding of low-pressure vessels. The introduction is devoted to the division of fusion welding methods. It is an overview of current technologies that are commonly used in engineering production. The primary objective is also to outline the problems and specifics of the production of weldments intended for areas with higher mechanical stress. Then follows a description of the basic technical parameters for the production of a correct weld bead. This mainly includes the calculation of heat input, the use of current indicator and the correct selection of shielding gas. The issues of heat affected area and the possibility of structural changes in the basic material are also dealt with in detail. The primary focus of all indicators is on the TIG method. The following section explains the issue of welding low-pressure vessels using a robotic arm and a single-purpose semi-automatic machine. The conclusion of the thesis is devoted to control mechanisms of welded joints.
