20.500.12556/DKUM-92235 Numerical simulation and experimental measurement of residual stresses in a thick-walled buried-arc welded pipe structure In this study, a numerical simulation of a single pass welding of two thick-walled pipes with the buried-arc method was performed in order to determine the residual stresses caused by welding. The numerical simulation procedure in the thermal analysis was performed by the element birth and death method while the structural analysis was performed simultaneously, without the application of the element birth and death technique in order to reduce the duration of the numerical simulation. The simulation results were validated by experimental residual stress measurements on the outside surfaces of the welded model using the X-ray diffraction technique. A good agreement between the results of the numerical simulation and experimental measurements was confirmed. buried-arc welding thick-walled pipe single-pass welding X-ray diffraction submodeling MAG welding obločno varjenje cevi z debelimi stenami varjenje z enim prehodom rentgenska difrakcija podmodeliranje MAG varjenje true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/metals © 2022 by the authors Članek v reviji 2025-03-24 11:53:41 2025-03-24 11:53:41 2025-03-25 03:09:41 0000-00-00 00:00:00 2022 0 0 Str. 1-14 iss. 7 (1102) Vol. 12 June 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-05-24 2022-06-26 2022-06-28 621.791:620.1 119786499 10.3390/met12071102 2075-4701 metals-12-01102.pdf metals-12-01102.pdf 1 305CDC5AB5D50D9C15104777829899B1 214d81c123c5cf96021bf53184faea2ee97de19834432d5c5abde80303ac256d b809ad22-089e-11f0-b559-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189595 https://www.mdpi.com/2075-4701/12/7/1102 0 bd47f092-089e-11f0-b559-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189596 Fakulteta za strojništvo 0 0 0
