How to determine the cracks on the surface of the angle
Angle steel can be composed of a variety of different stress members according to different needs. Due to its good weldability, plastic deformation properties and certain mechanical strength, angle steel is widely used in metal components, engineering structure frame and various building structures. However, due to improper processing, angle steel often produces cracks, so how should be determined angle steel surface cracks?
Understand the structural shape of the detection area, analyze the angle force situation, determine the specific detection method, through the detection instrument combined with the processing technology, to make a correct determination of cracks. Angle steel surface cracks to determine the detection of detection difficulties lies in the angle edge of its shape is irregular and the existence of arc over, with ultrasonic straight probe detection detection direction is single, it is easy to miss detection, with oblique probe detection, due to the formation of the end of the angle reflection, the defects of the determination of the difficulty.
The direction of the crack produced by the system bending is perpendicular to the angle length direction, and the crack direction is parallel to the angle length direction, and the crack is long and thin, sharp at both ends, so the crack is produced by the rolling process, after the system bending crack diffusion, crack characteristics are more obvious. If the crack direction is perpendicular to the length of the angle, the crack is produced by the bending process.
