Real Time Tracking Technology for Ultrasonic Flaw Detection of HFW Welded Pipe Welds
During the forming and welding process of HFW welded pipes,defects such as inclusions,cracks,and lack of fusion may occur.Ultrasonic testing can detect these defects,thereby effectively controlling the quality of the welds of HFW welded pipes.For HFW welded pipes with a length of 12-18 meters,due to the possible bending problem of the pipe along the axial direction,the weld may deviates from ultrasonic probes.In order to keep the probes right on the weld seam during testing,based on the design of real-time tracking technology for ultrasonic testing weld seam,an ultrasonic flaw detection weld tracking system for HFW welded pipes up to 18 meters in length was devel-oped.When the flaw detection speed is 1 m/s,the system can detect the weld deviation in time,and immediately adjust the position of the probe frame,so that the probes are kept locating on the weld,to ensure that all parts of the HFW welded pipe weld can be detected,effec-tively controlling the quality of the HFW welded pipe weld seam.
