It is a portable testing device that can easily detect residual stress (stress concentration areas) in magnetic metals.
This is a portable residual stress (stress concentration area) detection device using the measurement principle of the MMM method (Metal Magnetic Memory Method). It complies with ISO 24497, allowing for the identification of defective areas before issues such as corrosion and fatigue occur, making it a valuable tool for preventive measures. It is particularly suitable for rough flaw detection in welds. 【Features】 ■ Complies with ISO 24497 ■ Easily detects residual stress (stress concentration areas) ■ Enables identification of defective areas before issues like corrosion and fatigue arise ■ Capable of detecting early-stage microcracks, slag in welds, and pores that cannot be detected by eddy current testing ■ Multi-channel operation ■ A wide variety of probe types available (4 types) to suit different applications ■ Can measure through coatings

basic information
What is the MMM method? It measures the disturbance of the self-magnetic field recorded in magnetic materials. When the magnetic material is stable, the magnetic field is zero. If there are defects (such as tension, compression, corrosion, cracks, etc.), the self-magnetic field becomes disturbed and is recorded in the magnetic material. A scanning unit with a built-in high-sensitivity sensor measures the disturbance of the self-magnetic field.
