Ultrasonic Test System for SSAW Pipe Weld Seam

Spiral welded steel pipes are widely used in Oil, Natural Gas, Water and other flammable & nonflammable liquid conveyance and distribution pipelines, steel structures for construction and other general purposes by means of their wide size range.

Widely preferred longer lengths up to 18,5 m. considerably decreases the cost of pipeline construction resulting in less number of girth welds compared to shorter pipe lengths.

When weld ultrasonic testing, in order to track the weld automatic tracking, the probe is always in the frame just above the weld. The system uses laser vision technology to detect traces of the weld, using IPC and motion control components work together to reach out manual control, automatic track welds, adjust the probe holder the right destination location.

Laser weld ultrasonic testing automatic tracking system consists of a laser vision sensor, data processing means for controlling the composition and executing agencies. Laser vision sensor comprises a CCD camera and a semiconductor laser; data processing agencies, including image acquisition card, and industrial control computer; including PLC control mechanism and stepper motor drives; positioning actuator includes a skateboard, a stepper motor and connected institutions.

System in real time using laser vision sensor weld image; industrial control computer through a dedicated software processing to obtain the image feature points to calculate the deviation of the weld, width, and other parameters the wrong side, and then send control commands through PLC, the drive to drive a stepper motor driven skateboard and probe holder back to the correct position. Laser weld ultrasonic inspection system in the design and manufacture of automatic tracking process to fully consider the scene, laser vision sensor uses a high anti-jamming equipment , stable and reliable; data processing bodies and control mechanisms are used for industrial equipment, common good, low failure rate, easy maintenance; executive body of imported ball screw and linear guide rail, high precision, durable, good dustproof performance.

对于螺旋焊接超声检查，现在更常用的方法是更常用的方法，该方法是焊接管，布置在多个超声剪切波探针的两侧，并联运动检测管焊缝平行或垂直于缝焊缝缺陷。
