Abstract

The invention discloses a manual oblique nozzle fillet weld phased array scanning device capable of performing bidirectional scanning. The manual oblique nozzle fillet weld phased array scanning device capable of performing bidirectional scanning comprises a locking mechanism, an adjusting mechanism, a probe frame sliding bar assembly and a nozzle probe arm; the locking mechanism comprises a chainlink assembly and a locking assembly; the adjusting mechanism comprises a profile rod, an adjusting arm, an adjusting sliding block, a fastening screw and an adjusting knob; the probe frame sliding bar assembly comprises a probe frame, a sliding block installation plate, a vertical sliding block, a tension spring, a connection base, an arc sliding rail, a sliding rail leaning frame, a wedge blockclamp, a wedge block and an ultrasonic phased array generator; the nozzle probe arm comprises a left torsion spring probe arm, a right torsion spring probe arm, a nozzle wedge block clamp, a nozzle wedge block, the ultrasonic phased array generator and a nozzle displacement sensor; the wedge block is adjusted in the three-dimensional direction; therefore, the stability is good; the detection precision is high; the use range of multiple pipe diameters is satisfied by increasing and decreasing a chain link; the nozzle wedge block is arranged to simultaneously scan a welding line in the straightpipe direction and the nozzle direction together with the wedge block on a straight pipe wall; the scanning angle is enlarged; and the scanning effect is improved.

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
