Description
Technical Field
The invention relates to an ultrasonic phased array automatic detection system for a U-rib welding seam of a steel box girder, and belongs to the technical field of ultrasonic phased array detection.
Background
The orthotropic steel bridge deck is widely used in the process of constructing a large-span steel structure bridge, but due to the influence of vehicle load and structural stress concentration, various weld cracking phenomena caused by fatigue, particularly U-rib welds, occur occasionally, and the direct reason for the phenomenon is the effective penetration of the U-rib welds and the quality inside the welds.
At present, magnetic powder detection is mainly adopted for nondestructive detection of U-rib welding seams in steel bridge manufacturing standards (such as 'railway steel bridge manufacturing specification' Q/CR9211-2015 and 'highway bridge and culvert construction technical specification' JTG/T F50-2011) at home and abroad. As is known, magnetic powder inspection can only detect defects on the surface and near the surface of a weld joint, and cannot detect defects inside the weld joint. The thickness of a U rib plate used at present in China is usually 10mm, the fusion depth is usually required to be not less than 80% of the thickness of the U rib plate in a design file, and the overproof defect is not allowed in the fusion depth range. The conventional ultrasonic flaw detection is used for measuring the penetration rate of the U-rib welding seam with great difficulty. In recent years, the ultrasonic phased array is widely used for detecting the U-rib welding seam, but manual operation is still adopted, so that the labor intensity is high, and the detection efficiency is low.
