Summary:The article presents the analysis of electrodynamic processes during magnetic-pulse "expansion" of thin-walled tubular parts. The authors consider the cases where tubular parts are made by welding. As a result of welding, a deviation from the round shape occurs which requires calibration. Particular attention is paid to the case when the welding zone of a metal thin-walled tube touches the die. For the dynamic analysis of large deformations, the finite element method (FEM) based on the ANSYS software package is used, whose feature is the ability to implement a comprehensive solution to this class of problems. Using numerical calculations and optimization for pulsed metal forming, in particular pressure pulsed magnetic field (PMF), a nomogram was constructed to determine the required technological regimes that take into account the properties of the material and the pressure amplitude of the pulsed magnetic field.
