Designing and planning of welding technology for pressure vessel fabrication

Diplomsko delo obravnava konstruiranje in načrtovanje varilne tehnologije tlačne kuhalne posode. Posoda je izdelana v podjetju Linox solution d. o. o. iz Lendave. Prvi del diplomskega dela govori o konstruiranju tlačne posode, po standardu SIST EN 13445 in AD 2000 Regelwerk. Obravnavani so le ključni deli posode, kot so notranja in zunanja podnica, notranji in zunanji plašč ter cevni priključek na plašču. Drugi del diplomskega dela govori o načrtovanju varilne tehnologije za varjenje tlačne posode. Predstavljeni so postopka varjenja TIG in MIG/MAG ter avtomatsko varjenje na vzdolžnem in krožnem varilnem avtomatu. Za varjenje so bili izdelani WPS, kot jih zahteva tlačna direktiva. Na koncu diplomskega dela so opisane porušne in neporušne kontrole zvarnih spojev za odkrivanje napak v zvarnih spojih.The diploma thesis discusses the designing and planning of welding technology for a pressure cooking vessel. The vessel was made in the company Linox solution d.o.o. from Lendava. The first part of the thesis talks about designing the pressure vessel in accordance with the SIST EN 13445 and AD 2000 Regelwerk standards. It discusses only the main parts, e.g. the internal and external head, the internal and external shell, and the nozzle on the shell. The second part of the thesis talks about planning welding technology for pressure vessel welding. It presents the TIG and MIG/MAG welding processes and automatic welding on a longitudinal and circular welding machine. In accordance with the Pressure Equipment Directive, WPS was prepared. The final part of the thesis describes the destructive and non-destructive testing of welds for error detection
