Problems solved by technology

[0003] Although the existing form of static magnetic field can adjust the magnitude of the magnetic field by adjusting the excitation current, and then realize the control of the radius of rotation of the welding arc, the rotation frequency of the arc can only be changed by adjusting the magnitude of the excitation current, and the rotation frequency adjustment range Small, can not achieve independent control of the arc rotation frequency, which greatly restricts the movement of the arc, which has great limitations for improving the welding process

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 ...
