PAUT experimental device for pipe fitting

Abstract

Aiming at problems such as inconvenience of rotation of a pipe fitting during a PAUT contrast detection experiment, difficult operation of double probe detection, and response to experiments of pipe fittings of different specifications, the invention discloses a PAUT experimental device for the pipe fitting, and achieves PAUT automatic detection of the pipe fitting. The device includes a base, andthe base is provided with a vertical guide rail, a slide rail assembly, a first power member, hollow guide rails, a PAUT probe assembly, second power members that drive the hollow guide rails to movelongitudinally relative to the slide rail assembly; a horizontal pair of roller sets, a third power member, and a longitudinal first flat slide platform set are disposed on the base; and the second roller set is slidably connected to the first flat slide platform set, the first flat slide platform set is provided with a first slide platform power set that drives the second roller set to move longitudinally and adjusts the distance between shafts of the roller sets, the PAUT probe assembly can detect a circular seam of the pipe fitting transversely placed between the two roller sets, and the third power member can make the pipe fitting revolute around the axis of the pipe fitting between the two roller sets. The PAUT experimental device for the pipe fitting of the invention relates to thetechnical field of a detection device.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a PAUT experimental device for pipe fittings. Background technique [0002] In the field of non-destructive testing of steel structure engineering, the full English name of PAUT is Phased Array Ultrasonic Testing, which means phased array ultrasonic testing, which uses water as a coupling agent, and achieves beam deflection, focusing, etc. by controlling the emission phase of the chip according to the Huygens principle. As a result, the PAUT system can realize the detection of the circumferential weld and longitudinal weld of pipe fittings, and can simultaneously realize A-scan, TOFD grayscale image B-scan and phased array S-scan imaging. Ultrasonic phased array detection technology uses multi-element transducers of different shapes to generate and receive ultrasonic beams, and by controlling the different delay times of each array element in the transducer array to t...
