Robot automatic welding system for compartment body

The invention discloses an automatic robot welding system for a compartment. The automatic robot welding system comprises a central processing module, a visual recognition module, a welding seam quality detection module, a laser scanning positioning module, a smoke collecting unit and a welding module. The visual recognition module is used for positioning the position of a robot, judging the position of a compartment to be welded, collecting image information of a welding area in real time and collecting information of a welded seam area in real time, and the laser scanning positioning module is used for recognizing the welding area processed by the visual recognition module and extracting feature points; as an initial welding position and a reference position of autonomous guidance, tracking a welding seam in a welding process, and performing deviation guidance of a welding module; the welding seam quality detection module is used for carrying out online detection on welding seam quality according to the wel
