Problems solved by technology

However, the complex structure of the grid wing welding area, the thin thickness of the welded parts, and the small detectable space make it difficult to perform ordinary non-destructive testing methods. Therefore, a new non-destructive testing method that meets the requirements of rapid detection and full coverage detection is urgently needed

Abstract

The invention relates to a phased array ultrasonic detection device and method of a welding seam of a thin plate grid wing structure and relates to the technical field of non-destructive testing. Through use of a high-frequency phased array ultrasonic array transducer and a special-shaped wedge block fitting to the high-frequency phased array ultrasonic array transducer, the welding seam area of agrid wing structure is destructively detected and the whole welding seam area can be scanned without change of a probe position so that the convenience of non-destructive testing is improved. A mechanical arm clamps the transducer for scanning so that detection is intelligentized and efficient. The device and method solve the problem that the fast detection and the detection accuracy are contradictory and satisfy the demands of various types of automated testing.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a phased array ultrasonic testing device and a testing method for weld seams of thin-plate grid wing structures. Background technique [0002] Non-destructive testing (Non-destructive testing, NDT) is a kind of effective inspection and testing of the defect area inside the detection object by using a variety of physical and chemical methods without damaging the shape and performance of the tested sample. Test to determine the size, shape, location and nature of typical defect tissue to ensure that it can achieve the expected service life and safety in use. Ultrasonic Testing (UT) is the use of reflection, refraction, transmission, scattering, diffraction, Resonance and attenuation and other phenomena, by analyzing the energy amplitude, frequency, time and other information of the echo signal, the relevant information of the defect tissue or internal structure is ...
