Automatic adapter corner weld seam phase controlled array detection device capable of scanning in two ways

Abstract

The invention discloses an automatic adapter corner weld seam phase controlled array detection device capable of scanning in two ways. The device comprises a traveling mechanism, a locking mechanism,an automatic regulating module, a probe slider assembly, an adapter probe arm and a control mechanism, wherein the traveling mechanism and the locking mechanism are connected and arranged on the external edge of the adapter, a pull hook and a locking base plate of a locking component are connected with two end links of a chain component so as to form a complete chain ring of the locking mechanism,the automatic regulating module and the locking mechanism are fixedly connected, a slider installation plate fixedly connect the automatic regulating module and the probe slider assembly, and the adapter probe arm is arranged at one side of the lower end of a profile bar of the automatic regulating module. According to the automatic adapter corner weld phase controlled array detection device, a wedge and an adapter wedge of the adapter slider assembly are arranged, thereby enlarging weld seam detection angle range, and improving detection accuracy; the weld seam is scanned in the straight pipe direction and the adapter direction by the wedge on the straight pipe wall, so that scanning effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of detection of pipe joint welds, in particular to an automatic phased array detection device for joint 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 currentl...

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 between straight pipes of composite materials and vertically welded joints. The fixing method of the detection device and the path of the probe cannot be effectively controlled. Guarantee the completion of inspection work
