Qualification of welding procedure for cobalt plus heat-resistant stainless steel alloys
 Teuer, Tomáš ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
This thesis deals with the welding of heterogeneous materials, namely cobalt and heat-resistant stainless steel alloys refractory GTAW (WIG). The main objective is to develop a preliminary specification of the pWPS welding procedure for a particular component and its subsequent qualification of the WPQR welding process. Furthermore it is necessary to set requirements of mechanical testing and differences for qualification requirements according to EN ISO 15613 for this welding component.

Implementation of automatic welding machine to production of fittings
 Cícha, Tadeáš ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The Diploma Thesis is focused on the implementation of FCAW welding technology to the manufacturing process of a mechanical engineering company. One part of implementation is partial automation of manufacturing process with positioner machine which is connected to the welding source. Practical part of Diploma Thesis includes the verification of the weldability of used materials and assigning of pWPS for subsequent qualification of the welding process WPQR with the welding technology FCAW.

Qualification of welding procedure for aluminium alloy AW-5083 H111
 Krejza, Jan ; Mrňa, Libor (referee) ; Sigmund, Marian (advisor)
The diploma thesis deals with the qualification of welding process of aluminum alloy EN AW-5083 H111. This aluminum alloy was used to make a Venturi tube. Therefore, a literature review has been developed dealing with the properties and use of aluminum and its alloys. The next chapter deals with the weldability of aluminum, aluminum alloys and the weldability of EN AW-5083 alloy. Part of the work is devoted to the used TIG method and its specifics when welding aluminum materials. The practical part of the thesis deals with the actual qualification of welding procedures according to the relevant standard and evaluation of production conditions according to the product standard. The last chapter deals with the overall manufacturing process of the Venturi tube.

Welding method 131 (MIG) according to DIN EN ISO 4063 with a focus on analysis and comparison of the circumferential welding of aluminum pipe welding machine for welding machines BKM / BRP compared to manual semi-automatic welding
 VIK, Radovan
In the first part there are defined the basic terms used in the welding of aluminium and its alloys with the repect of related standards. The next part of the thesis described the hand welding of aluminium by the flame welding, arc welding and other special welding methods. The practical part focuses on the defects generated during welding of aluminium and its detection and iterpretation. The final part deals with the semi-automatic and automatic welding of aluminium and compares both methods.
