Abstract
An electromagnetic apparatus for active intervention to a shape of a molten pool is provided. In the present invention, a workpiece is placed on stepped surfaces of a test bench. Upon power on, a metal rod rotates to generate a toroidal magnetic field centered on the metal rod, and the toroidal magnetic field acts on the molten pool to generate an induced current. The induced current generates Lorentz force under the action of the magnetic field, which acts perpendicularly on an outer surface of the molten pool, thereby changing the height, depth and width of the molten pool, and finally realizing the active intervention to the molten pool shape.
