The portable long-pulse infrared thermal imaging inspection system is an advanced technology equipment that conducts non-destructive testing using long-pulse thermal excitation. The entire system is based on domestic components and has independent intellectual property rights. By emitting controllable long-pulse thermal excitation, the system penetrates the tested object. When defects such as delamination, layering, cracks, and weld separation or leakage exist in the material, the thermal conduction characteristics at the defect site will change, resulting in a difference in temperature distribution on the corresponding surface area compared to the surrounding normal area. The temperature field changes on the surface are recorded by the infrared thermal imager, and then the three-dimensional distribution of internal defects or structures is reconstructed.
Main features:
It is suitable for industrial inspections of composite materials, metal components, etc., and can achieve automatic non-destructive and quantitative non-destructive evaluation. It has advantages such as non-contact, wide applicability, high speed, large area, simple operation, intuitive and understandable detection results, quantitative measurement, and online in-service. The technical indicators reach the international advanced level. The product has achieved significant independent innovations in pulse excitation source, algorithm, automatic control, and intelligence. It has multiple successful application cases in carbon fiber composite materials, engine blade structure inspection, new energy battery inspection, and bridge inspection, breaking the international blockade. In the future, it can be widely applied in aerospace, nuclear industry, power, military industry, new energy, construction and other fields.
