Problems solved by technology
[0002] In the field of testing, metal tubes are often used to manufacture various parts, that is, the surface of the metal tube is processed such as slotting. In the current slotting device, the metal tube to be processed is fixed on the rotating shaft of the motor, and then the The tool is pressed against the surface of the metal pipe to be processed. When the motor drives the rotating shaft to move, the metal pipe to be processed is grooved by the tool. However, when the metal pipe welded by two metal pipes is grooved, due to the Due to the limitation of length, it is impossible to complete a weld with one electrode, so there is a problem of uneven connection between the front and back of the weld at both ends, so the end of the weld is easy to crack. Therefore, in this type of welding by two metal pipes When the formed metal pipe is grooved, it is necessary to monitor the end of the weld to avoid unnecessary loss

The invention provides an online monitoring method for a weld seam ending position. The online monitoring method is used for monitoring the weld seam ending position in the grooving process of a metalpipe formed by welding two metal pipe bodies. According to the online monitoring method, a detecting rod is driven to rotate by utilizing a testing motor, the rotating speed of the detecting rod is enabled to be consistent with the rotating speed of the metal pipe to be monitored, and an image acquisition device is arranged at the front end of the detection rod and is used for monitoring the weldseam ending position; and the metal pipe to be monitored rotates at a fixed rotating speed in the machining process, in order to enable the image acquisition device at the front end of the detectionrod to fixedly collect the image at the weld seam ending position, the rotating speed of a machining motor is detected by utilizing a rotating speed testing device and is transmitted to a rotating speed control device, the rotating speed control device sets the rotating speed of the testing motor to be consistent with the rotating speed of the machining motor.
