Manual ultrasonic testing of ERW steel pipe welding joint
DataTime:[2016-12-21]
The residual defects in erw steel pipe ultrasonic testing is an important reason for failure of the weld, causing defects missed is inappropriate due to a probe parameter selection, disturbing wave effects and burr flaw echo echo does not distinguish between such a variety of factors.
Steel ultrasonic testing to detect delamination defects can reduce the subsequent generation of weld defects; weld inspection by the online automatic ultrasonic testing, offline auto detection, manual ultrasonic testing is completed. Online automatic ultrasonic testing set after the internal and external deburring, ultrasonic probe temperature by several groups for real-time monitoring of the weld, the weld quality real-time monitoring is an effective means of welding seam produced incomplete fusion, scraping the inner seam is not timely in addition to other issues, which can be in this position detected in a timely manner, contribute to the timely adjustment of the inner seam welding process and scraping device, greatly reducing the generation of weld defects, to eliminate the appearance of a large number of substandard products. Offline ultrasonic testing of the weld is the ultimate intrinsic quality detection means, which is to ensure the quality of the main ERW pipe weld points, offline pipe probe positioning can guarantee to more accurately detect defects. Automatic ultrasonic defect is detected, manual ultrasonic testing is generally used to further identify. Automatic ultrasonic testing process layout and manual ultrasonic probe and probe selection process is basically the same.
