Offline analysis method for stainless steel train body CMT welding spattering

The invention discloses an offline analysis method for stainless steel train body CMT welding spattering. The method comprises the following steps that a camera is installed on a camera installation device, and the camera is electrically connected with an industrial control computer; in the welding process, the camera photographs a to-be-welded workpiece, image data in the welding process is collected, and the image data is transmitted to the industrial control computer; the image data is processed, the background and an electric arc in the image data are removed, only spattering light spots are reserved, and the area of the spattering light spots is adopted as the measure of the spattering amount. The offline analysis method for stainless steel train body CMT welding spattering is good in adaptability, high in reliability and powerful in function. The system can be effectively integrated with a welding device together to complete spattering monitoring and perform offline analysis in the welding process. Acco
