The invention provides an arc welding robot welding monitoring system which is based on visual sensing in the arc welding robot technical field. The invention comprises a welding robot, a robot controller, a visual sensing system, an interface circuit device, a main control computer, and a dual inverter arc welding power source; wherein, the visual sensing system dynamically collects the images ofa welding pool and transmits the images to the main control computer which receives the image information which is provided by the visual sensor and achieves the image processing; furthermore, the main control computer adjusts the dual inverter arc welding power source and controls the welding robot through the interface circuit device according to the processing results; the interface circuit device consists of a simulation signal output sub-module, a welding switch and process state detection sub-module and a robot controller general I/O sub-module; the welding robot receives a moving instruction signal which is em
