Title of the thesis:Design and approval of welding procedures (WPS) gas coolers made of steel grade. 1.4462 (X2CrNiMoN 22-5-3)
Summary:In accordance to the requirements of EN ISO 15614-1, deals this study with the determination and subsequent with the verification of provided preliminary welding procedure specification (pWPS) of butt welded joint with duplex metal - steel grade 1.4462 (X2CrNiMoN 22-5-3). Based on the data and the welding parameters mentioned in the pWPS was welded the amount of test samples with manual method MAG + TIG welding, which required the standard. The test samples were subjected to non-destructive and destructive tests to verify the correctness of the welding parameters. The test results and data from the proposed preliminary pWPS were summarized in the procedure qualification record of welding (WPQR). The goal was not only to design the technological process for welding of butt welded sheets of duplex steels, but also to verify its accuracy by destructive and non-destructive testing.
Key words:coat gasoline cooler, stainless steel, Welding procedure, MAG + TIG welding
