How to detect crack of steel structure quickly and effectively
Cracks are generally observed on the weld or on the surface of the component. Large cracks can be seen with the eye, but there is often a capillary crack near the big crack. This is not necessarily an eye view, but these cracks can be detected with magnetic particle inspection
Crack detection usually adopts the method of magnetic particle inspection, of course, the ray flaw detection method can achieve the same effect, and is more effective for the deeper crack, but the cost is high. Ultrasonic theory can be done, but manual inspection at the scene, the workload is too large, basically impossible to achieve.
