TL;DR: In this paper, a small-diameter tube nondestructive testing method based on a phased array ultrasonic flaw detector is proposed, which includes the following steps: carrying out CIVA and sound field simulation on a detected workpiece, debugging the phased array UL detector by a simulation test block and verifying on a simulated workpiece; grinding two sides of a welding seam of the detected work piece, detecting the detected UL detector ground smoothly by the debugged UL detector; and analyzing the detection graph to obtain a detection result.

TL;DR: In this article, the utility model relates to a nondestructive test field, concretely related to a sweep and look into recorder for large-caliber pipe welding seam phased array ultrasonic testing, press from both sides and position sensor including magnetic wheel, support, probe, the support comprises support mobile jib and rotation axis.

TL;DR: In this paper, a fully-focused detection technology for coarse-grained material weld joints is proposed based on an M2M phased array ultrasonic flaw detector, which is used for non-destructive testing.

TL;DR: In this paper, a small-diameter tube phased array ultrasonic test sensitivity adjusting method is proposed to improve the reliability of sensitivity debugging, and therefore the accuracy of test results.

TL;DR: In this article, the reference block main part is the same with the detected workpiece material, the unity of the velocity of sound when guaranteeing the sensitivity inspection, can reflector A and reflector B apart from surperficial 5mm, 10mm, according to the requirement of phased array ultrasonic focusing rule design, accomplish 4mm respectively reference sensitivity calibration in the 15mm, V type welding seam embeds the gas pocket defect, do not fuse defect and crack defect cover the welding seam on in, the three position degree ofdepth and position down to design volume nature defect
