Abstract
This study investigates the impact of magnetic fields on the microstructure and mechanical properties of Metal Inert Gas (MIG) welds. Steel plate samples were welded under the influence of a magnetic field generated by permanent magnets, with simulations and experimental analyses used to evaluate weld quality. Key parameters such as magnetic field strength, magnet rotation speed, and distance were varied to assess their effects on the weld structure. The results revealed that applying a dynamic magnetic field improves weld penetration, alters grain structure, and reduces defects, enhancing mechanical strength and weld integrity. Finite element modeling was employed to simulate the effects of rotating magnets on the welding area, showing a uniform temperature distribution and significant changes in the fluid flow of the molten pool. These findings provide insights into optimizing welding parameters and demonstrate the potential for using magnetic fields to enhance welding processes, offering practical applications for advanced manufacturing.
