ASEM Implementation Example

As part of a pilot initiative to evaluate the condition of bridge structures, IHI Inspection & Instrumentation Co., Ltd. (IIC) has introduced an industrial non-destructive inspection system (ASEMindtec).
The system is based on ASEM (Acoustically Stimulated Electromagnetic Method) technology, which enables visualization of the internal electromagnetic state of steel without removing surface coatings. This allows for the detection of deterioration and stress changes beneath coatings—challenges that conventional non-destructive methods have struggled to address—thus contributing to more advanced infrastructure maintenance. IIC is currently conducting on-site validation trials to assess the effectiveness of ASEM-based inspection under real-world conditions

System Setup

ASEM detects material degradation and property changes through variations in piezoelectric and magnetostrictive effects. It may enable evaluation that was previously deemed impossible.
System specifications can be customized based on intended use.
Examples: corrosion, deformation, embrittlement, residual stress, metal fatigue, and material inhomogeneity invisible to the eye.
