dc.description.abstractWelding neck flanges are commonly manufactured by radial-axial ring rolling (RARR). The service conditions of these elements are very demanding (mechanical loads and corrosive environments). For this reason, materials such as super duplex stainless steel (SDSS) are used, which could present workability problems under certain process conditions. In this work, a study of forming defects and failure occurrence in the RARR of SDSS flanges has been proposed. Firstly, a finite element model of the industrial RARR process was developed and validated. Then, a multivariate factorial analysis based on a virtual design of experiments was performed to identify the determinant parameters of the process. The diameter of the mandrel was identified as the most determinant parameter. An increase in diameter reduces the probability of developing underfilling defects and the development of cracks in the flange neck. The mandrel radial speed has no significant effect on the cracking of underfill defects while reducing the rotational speed of the king-roll could improve the uniformity of the deformation distribution in the flange section.en
