Proposal of technological procedure for welding pressure vessel

The work presents a proposal for a suitable technology for the welding of the pressure vessel of the LPG gas phase separator. There are three different methods of welding of the separator body proposed and the economics of producing the separator for a given series of pieces is assessed. There is a comparison of hand electrode welding, MAG welding and TIG welding. Further, a brief overview of possible types of non-destructive testing is added and the three selected tests are properly executed and detailed. An overall evaluation of the experiments performed is included and the possible future development outlined
