Production of Pipe Section Elbow (R=1D) with manual metal Arc Welding
Hráček, Jan ; Staněk, Vlastislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis is the final piece of work of a distant form of studies majoring in B-STG Machinery technology and proposes the technology of production of pipe section elbow (R=1D) from seamless pipe DN500 (O508 x 14). The thesis puts forward and evaluates from the technical-economical point of view four kinds of welds combining additional materials from ESAB company for manual metal arc welding using methods 141 and 111. The construction design is made by the ČSN EN 13 480 criteria – metal industrial pipes. The welds of pipe section elbow are designed and done by TPE 10-40/1771/81 – general technical rules of assembling welding pipes of powerplants VVER type valid for EMO 12 (Mochovce powerplant, units 1 and 2). For the construction and modeling of the pipe section elbow ratio (R=1D) programs by Autodesk were used.

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.
