The invention provides a control method and device for cutting a welded pipe, a cutting system, equipment and a medium, and the control method for cutting the welded pipe comprises the steps: controlling a visual part to collect a template image of a first mark on a first pipe when the first pipe is installed on a machine tool; identifying color information of a first mark from the template imageas template color information; when a second pipe is installed on the machine tool, controlling the second pipe to rotate around the center, and collecting a to-be-recognized image of the surface of the second pipe; if detecting that the current color information of multiple pixels in the to-be-recognized image matches the template color information, determining the rotation angle of the second pipe relative to the reference position at the moment as a target angle; and according to the target angle, controlling a laser cutting head to machine the second pipe, so that the laser dotting position of the laser cutting head avoids the target angle during machining.
Description
technical field [0001] The invention relates to the field of pipe processing, in particular to a control method, device, cutting system, equipment and medium for cutting pipes with welds. Background technique [0002] Due to process limitations, metal pipes will leave an axial weld (except for seamless metal pipes) when they are formed. In the process of pipe cutting, drilling and other pipe processing, this weld will have adverse effects on the processing (such as the pipe will crack in the open space during bending), so the position of the weld seam needs to be detected in advance during processing . [0003] In the existing related technologies, the position of the welding seam is usually found by manual search, which is prone to errors and is time-consuming and labor-intensive. Contents of the invention [0004] The invention provides a control method, device, cutting system, equipment and medium for cutting pipes with welds, so as to solve the problem that manual se...
