Problems solved by technology

Ultrasonic manual detection of TKY pipe joint welds, because the detection results depend on the experience and technology of the testing personnel, it is prone to misjudgments and missed judgments, and it takes a long time to take the cross-section for each defect location Shape, drawing and positioning measurement, the workload is relatively large, and there are problems in terms of repeatability and reliability
Moreover, for the complex three-dimensional surface structure of TKY pipe joint welds, manual ultrasonic testing cannot realize the visualization and real-time recording of test results

Description

Technical field [0001] The invention relates to the field of ultrasonic phased array detection, and more particularly to an ultrasonic phased array detection system for TKY pipe joint welds. Background technique [0002] In recent years, with the continuous deepening and development of marine resource development, many countries in the world have built many new marine resource development facilities, including fixed offshore platforms, mobile offshore platforms, and submarine pipelines. These offshore structures are often affected by ocean storms. Infiltration and ocean corrosion, cracks are likely to appear in the welds of the pipe joints, which endanger the safety of national property and personnel. Therefore, the non-destructive testing of offshore platform structures is of great significance. The structure of an offshore platform is generally composed of a variety of steel conduit structures, and its pipe nodes can be divided into three types: T, K, and Y according to their d...
