Non-destructive testing system and method for special welding of steel structure

Abstract

Disclosed are a system and a method of nondestructive testing of steel structure special type weld. The system of the nondestructive testing of the steel structure special type weld comprises an image collecting device, an ultrasonic signal collecting device, an upper monitor module and a power source. The image collecting device is connected with the upper monitor module and is used for collecting a steel structure weld joint image at real time and then the steel structure weld joint image is sent to the upper monitor. The ultrasonic signal collecting device is connected with the upper monitor module and is used for collecting an ultrasonic signal and generating an ultrasonic wave form image used for analysis. The upper monitor is used for analyzing the collected image and the collected ultrasonic wave form,and locating a weld joint defect,and analyzing the weld joint defect situation, and then obtains defect particular information and defect parameter. The image collecting device and the ultrasonic signal collecting device are respectively connected with the power source, and the upper monitor module and is used for supplying power to the image collecting device and the ultrasonic signal collecting device and the upper monitor module. The system and the method of the nondestructive testing of the steel structure special type weld have the advantages of being easy to operate, high in measurement precision and accuracy, high in work efficiency, convenient and easy to use and high in real-time property.

Description

technical field [0001] The invention relates to the field of steel structure detection, in particular to a nondestructive detection system and method for special welding of steel structures. Background technique [0002] Steel structure welding is a relatively special physical metallurgical process. There are many reasons that can affect the welding quality of welded components, such as the defects of the welding process, the problems of the equipment itself, the influence of materials and other factors, which will bring disadvantages to the mechanical properties of the steel structure. influences. The principle of non-destructive testing technology used in steel structure welding is to detect the quality of the welding without affecting the performance of the steel structure, and to identify the defects by changing the parameters of light, magnetic field and vibration caused by welding defects . [0003] At present, the commonly used detection methods for internal defects...
