Problems solved by technology

[0002] In the process of laser processing, by coupling the electromagnetic field and controlling the size and direction of the Lorentz force, the molten pool can be controlled, the defects such as pores and cracks in the solidified structure can be reduced, and the grains of the structure can be refined, so as to realize additive manufacturing zero. To improve the mechanical properties of components, the existing magnetic field generating devices are all single magnetic field or electromagnetic field assisted laser manufacturing devices. In addition, the direction of the magnetic field and the gradient of the magnetic field distribution of these devices are not adjustable, and it is impossible to control the Lorentz force of the molten pool flexibly and conveniently. When the device is started, the heat emitted by the coil is difficult to dissipate, and the coil In a high temperature environment, the electromagnetic conversion efficiency is low, and it is prone to failure. Therefore, there is an urgent need for a combined magnetic core magnetic field generator with improved magnetic gathering ability to solve this problem.
