Construction steel structure weld ultrasonic phased array detection technology

一种建筑钢结构焊缝超声相控阵检测工艺

Abstract

The invention relates to a construction steel structure weld ultrasonic phased array detection technology. The technology employs an ultrasonic phased array detection instrument (1) and an ultrasonic phased array probe (2) to detect the weld defect (7) in a weldment's weld (6), and consists of the steps of: 1. instrument setting; 2. instrument calibration; and 3. scanning detection. Specifically the phased array detection instrument comprises a host, the probe, software, a scanning device and accessories. According to the detection technology provided by the invention, ultrasonic phased array is employed to scan the weld only 1 to 2 times so as to finish detection, and the detection result and image are stored. The technology can effectively shorten the detection cycle, can provide beneficial reference basis for ensuring safety assessment of construction steel structure, reduces the occurrence of safety accidents, and provides reference for design to reduce conservative design, enriches construction steel structure weld nondestructive detection methods, improves work efficiency and quality, and escorts construction steel structure welding quality.
