Ultrasonic Test System for Weld Seam
DataTime:[2016-9-15]
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.
For spiral weld ultrasonic inspection, testing is now more commonly used method, which is to weld pipe arranged on both sides of a number of ultrasonic shear wave probes, parallel motion detection pipe weld seam parallel or perpendicular to the seam weld defects.
