Omnidirectional steering type welding robot and using method thereof

The invention relates to the technical field of welding robots, and discloses an omnidirectional steering type welding robot which comprises an electric rotary table, a mechanical arm, a laser welding device, a sensor set and a control box. The bottom end of the mechanical arm is installed at the top end of the electric rotary table, and the laser welding device and the sensor set are both installed at the other end of the mechanical arm; and a processor, a data acquisition module, a motion control module, a deviation identification module, a mode selection module, a welding control module and a man-hour recording module are arranged in the control box. According to the omnidirectional steering type welding robot and the using method thereof, the welding process is detected through the sensor set, data is processed through the data acquisition module, transverse and height welding seam deviation is corrected through the deviation recognition module, the motion control module accurately controls the control qu
