Electromagnetic auxiliary K-TIG multi-position automatic welding system and control method

The invention discloses an electromagnetic auxiliary K-TIG multi-position automatic welding system and a control method, and the electromagnetic auxiliary K-TIG multi-position automatic welding system comprises an industrial personal computer, a welding robot, a K-TIG welding machine, an excitation power supply, a visual inspection camera, a K-TIG welding gun, an excitation device and a to-be-welded base material. And sending into the industrial personal computer for intelligent operation so as to obtain the position of a to-be-welded weld joint and the penetration state and predict the metal flowing trend of a molten pool in advance, so that the motion trail of the welding robot, the output current of the K-TIG welding machine and the output current and direction of the excitation power supply are regulated and controlled, the excitation device is controlled to generate a magnetic field, and Lorentz force is formed to promote arc deflection. And molten pool metal dripping caused by the gravity effect is avoi
