Prediction of the Weld Pool Stability by Material Flow Behavior of the Perforated Weld Pool. [PDF]
Materials (Basel), 2020 This article presents the application of a computational fluid dynamics (CFD) finite volume method (FVM) model for a thermo-mechanical coupling simulation of the weld pool used in variable polarity plasma arc welding (VPPAW). Based on the mechanism of the additional pressure produced through self-magnetic arc compression and the jet generated from ...
