Steel structure materials are indispensible for urbanization and modernization progressing at full swing. However, due to the periodic fatigue damage day after day, some steel structures may have safety hazards. In this case, it is particularly important to adopt Non-destructive Test (NDT) to secure the safety. NDT is a technology that can carry out testing directly in the field without damaging parts or materials, and it is more efficient. At present, there are five NDT methods: Ultrasonic Testing, Radiographic Testing, Magnetic Particle Testing, Penetrant Testing and Eddy Current Testing. However, all these methods have limitation. The magnetic inspection scanner with high sensitivity, high response speed and strong anti-interference ability, developed by Guocang Intelligent based on metal magnetic memory effect, can realize magnetic scanning NDT of steel structure materials accurately, in real time and efficiently. For the cases where one of the 100 wire ropes for elevator breaks; where the spacing between the rails changes by 0.01 mm; where "creepage" and damage invisible to the eyes occur to the steel rail; Guochuang Intelligent Magnetic Scanning Inspection System can be used to quickly and accurately detect the defects or scars of railway tracks, axles, wheels, wire ropes (elevator cranes, conveyor belts, bridge suspension cables, etc.), steel pipes, steel structure abnormals (aircraft landing gear, etc.), and steel structure frames of buildings, and describe the scar and defect grade, shape and size of steel structural parts, etc. by relevant special algorithms.

Guochuang Intelligent Magnetic Scanning Inspection System can also be used to carry out the whole non-contact NDT for raw materials for manufacturing, each intermediate process link to the final product, carry out testing for the equipment in service as well as forecast for damage development trend. It attracts the attention of the industry and the market with the advantages of excitation free, easy operation, high efficiency, accurate testing effect, etc., and has extremely broad development and application prospects.
