Typical Image Interpretation of Phased Array Ultrasonic Inspection of Welds in Pressure Equipment
摘 要
介绍按ASME法规2009增补版要求, 用超声相控阵技术检测承压设备焊缝时, 根据相控阵扇形(S)扫描图像, 结合相应探测布置截面图, 对典型焊接缺陷检测图谱进行识别和评定的应用案例。所涉及的焊接接头为相对于X型坡口双面焊有一定检测难度的V型坡口单面焊和T型接头组合焊, 焊接缺陷包括焊趾裂纹、焊道下裂纹、内表面开口裂纹、坡口未熔合、根部未焊透以及密集气孔等。同时, 比较了相控阵检测的定量结果与实际缺陷尺寸。
Abstract
Based on the latest ASME Code(revised and enlarged edition 2009) requirements of inspecting welded joints in pressure equipment by ultrasonic phased array technology, this article presented some cases of reading typical PA images in consist of PA S-scan displays of common welding defects and the sectional view of used inspection arrangement. The inspected objects were single-V groove welds and T-joint butt welds, for which there were some difficulties in inspection comparing with the common double-X groove welds. The defects included toe cracks, underbead cracks, inner-surface breaking cracks, side-wall lack of fusion, incomplete root penetration, and porosity and so on. A comparison between the sizing result by PA inspection and the actual defect size was also given.
