Another non-destructive testing method is magnetic particle testing (MT). This method is only applied for the examination of magnetizable (ferromagnetic) materials such as iron, cobalt and nickel. The material to be examined is turned into a magnet. If the magnetic field is pulled over the soft iron, the magnetization suddenly disappears and the material returns. However, if the magnetic field is withdrawn from carbon steels, this feature may continue for a while. Magnetic field method transverse errors, electric field method longitudinal errors are detected.
The basic principle of the magnetic particle inspection method is to generate leakage magnetic current in the discontinuities of the surface of the magnetizable materials and to collect the iron powders sprayed on the surface of the material over these cracks in the material. In general, discontinuities at or just below the surface of the material can be detected by this method.
The Regulation on the Health and Safety Conditions in the Use of Work Equipment issued by the Ministry of Labor and Social Security was issued to regulate the minimum requirements for the health and safety of work equipment used in workplaces. Details of the Annex to the Regulation on Maintenance, Repair and Periodic Inspections (Annex 3) are provided.
Our company is non-destructive within the framework of inspection services, also provides inspection services with magnetic particles.
