In steel engineering, cracks are hazardous defects, which have a spread, regardless of the size of the crack length required to deal with.Guangzhou galvanized angle factory has its own set of detection methods for the phenomenon of galvanized angle.
Galvanized steel angle factory products can be composed of a variety of different components of the force according to the different needs of the structure, but also for the connection between the components.Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
Galvanized angle steel manufacturers know the risk of crack angle, how to effectively detect and determine the angle of steel cracks, to ensure product quality is of great significance.According to the position of the crack is divided into surface cracks and internal cracks, surface cracks using magnetic detection, internal cracks using ultrasonic testing.How to effectively detect cracks.Need specific structure, specific treatment.
Transmission line angle steel bending crack detection and determination, first understand the structure and shape of the detection area, analysis of the workpiece stress situation, to determine the specific detection method, through testing equipment, analysis of crack characteristics combined with the processing technology, and ultimately make the correct judgment on the crack.Angle detection difficult in that the angle of the edge of its irregular shape and the presence of excessive arc, with a single ultrasonic probe detects the direction of the straight, it is easy to miss, when detected by the oblique probe, due to the formation of the end of the angle of reflection, difficult to determine the defect. 角 角 角 鋼For this place with magnetic powder and ultrasonic two detection means to test has a good effect.First, whether there is a surface defect with magnetic detection angle edge, if there is no surface defects, then the ultrasonic probe oblique detection, crack amplitude is characterized by a defect wave and an end angle reflection amplitude, if there is a crack defect, the instrument displays only one end angle reflection amplitude.
We recommend that you choose galvanized steel angle manufacturers, do not blindly consider the price of galvanized steel angle, product quality is the primary factor.
