A manual phased array scanning device for fillet welds of inclined pipes with bidirectional scanning

Abstract

The invention introduces a manual phased array scanning device for bidirectional scanning of fillet welds of miter pipes, which includes a locking mechanism, an adjusting mechanism, a probe frame slide bar assembly and a pipe probe arm; the locking mechanism includes a chain link assembly and locking components; the adjustment mechanism includes a profile rod, an adjustment arm, an adjustment slider, a fastening screw and an adjustment knob; the probe frame slide bar assembly includes a probe frame, a slider mounting plate, a vertical slider, a tension spring, a connecting seat, Arc slide rail, slide rail support, wedge clamp, wedge and ultrasonic phased array generator; takeover probe arm includes left torsion spring probe arm, right torsion spring probe arm, takeover wedge clamp, takeover wedge, ultrasonic Phased array generator and take over displacement transducer. The adjustment of the wedge in the three-dimensional direction has good stability and high detection accuracy; the use range of various pipe diameters can be satisfied by increasing or decreasing the chain link; The welding seam is scanned in the direction of the connecting pipe, which expands the scanning angle and increases the scanning effect.

Description

technical field [0001] The invention relates to the technical field of detection of pipe joint welds, in particular to a manual phased array scanning device for angled pipe fillet welds capable of bidirectional scanning. Background technique [0002] As a green detection method, ultrasonic phased array detection adopts a multi-chip organically arranged probe, uses computer technology to control the sound field deflection, focusing and receiving sound waves of the probe, and uses digital scanning imaging technology to scan at the same time, and the detection results are output as three-dimensional images and storage, providing rich information for defect location, quantification, and characterization; detection data can be analyzed in real time or remotely, with high detection sensitivity, high efficiency, low labor intensity, low detection cost, and safety and environmental protection. [0003] For non-destructive testing of fillet joints of composite pipes, there is current...

Problems solved by technology

[0004] 1) Limited by the current domestic standards, the current GB / T32563-2016 (Phased Array Ultrasonic Testing Method) and NB / T47013.3-2015 (Non-destructive Ultrasonic Testing of Pressure Equipment) standards do not involve composite material joints Testing methods for fillet joints;

[0005] 2) Design the ultrasonic testing requirements for the fillet joints of composite material pipes, and the testing cannot be implemented due to the lack of support from testing standards

[0007] 4) Existing ray, conventional A-buried ultrasound, diffraction time-lapse ultrasonic, magnetic particle and penetration testing methods for composite fillet joints all have deficiencies and cannot meet the testing requirements

[0009] Moreover, the existing scanners are only suitable for the detection of straight pipe butt welds, and cannot be used for the detection of curved surface welds of straight pipes and inclined joints made of composite materials. The fixing method of the detection device and the path of the probe cannot be effectively controlled and cannot be guaranteed. Completion of inspection work
