ABSTRACT

The paper presents a system for monitoring of operational safety of ferromagnetic structures used in civil engineering, machine construction and power engineering. The system is based on sensors of the residual magnetic field (RMFM) distribution. A change in values of individual components of the residual magnetic field informs in advance about the appearance of areas with a raised level of stresses or stress concentration zones and identifies micro cracks. The paper presents numerous examples of identification of hazard areas both in machine construction (forging press drive shafts) and in civil engineering (transporter crane steel structure). The information obtained from the system for monitoring of operational safety of ferromagnetic structures has already made it possible to take appropriate preventive measures to avert a major catastrophe.

Keywords: ferromagnetic structures, residual magnetic field, micro cracks, cracks.
