Description

technical field [0001] The invention relates to a rotating magnetic field generating device for controlling a welding arc, which is applied in the field of welding technology. technical background [0002] The magnetic field control welding technology is to control the welding arc through the external magnetic field, affect the droplet transfer and welding pool, and then control the welding process and improve the welding process. The existing magnetic field forms used in welding technology at home and abroad mainly include transverse magnetic field, longitudinal magnetic field and sharp-angle magnetic field, etc., but these magnetic field forms are all static, that is, the motion of the welding arc is controlled by the static magnetic field. A large number of experiments have proved that these magnetic field forms can better control the welding arc, and the radius of rotation of the welding arc can be controlled by adjusting the size of the magnetic field, which can affect ...
