A Geometrically Parameterized Quasi-Stationary 3D Model for High-Frequency Induction Tube Welding

This paper presents a 3D multiphysics finite element framework for simulating high-frequency induction welding of tubes. The model couples a time-harmonic magnetic scalar potential formulation with a stabilized quasi-stationary advection-diffusion heat transport equation to accurately predict electromagnetic and thermal fields under industrial operating conditions. The framework incorporates parameterized geometry generation and semi-automated, physics-tailored mesh construction.
