TASETO JIKI CHECK Magnetic Particle Inspection
Product Made in Japan
Manufacturer: TASETO
Model: JIKI CHECK
Applications
Ferromagnetic metals (mild steels, high
tensile steels, steel castings)
● Features
1. Excellent in detecting surface flaws on ferromagnetic steels (unusable for non-magnetic materials).
2. Can also detect flaws that are not open to the surface.
3. Low testing cost
4. LED Blacklight is cordless
● Principle
Applying a high current to a magnetized object, or exciting an object placed in a strong magnetic field causes the magnetic field to bend by discontinuities such as cracks or pinholes, which exist on the object surface or relatively shallow subsurface, to leak out at the defective surface as if magnetic poles were produced there. If you apply TASETO JIKI CHECK to the leakage surface, its magnetic particles are absorbed over a wide range by the defective surface, thus making minute flaws visible to the naked eye. The magnetic particle testing method employs the principle.
Key：1. Item to be inspected 2. Magnetic particles 3. Magnetic field 4. Surface flaw 5. Internal flaw 6. Magnetic pole 7. Flaw
Testing Method
The magnetic particle testing follows the procedure as follows.
Pre-cleaning
Magnetization (direct current, current induction, prod, coil or yoke method)
Application of TASETO JIKI CHECK
(continuous, residual, spraying, immersion, wet or dry method)
Interpretation (under white light or black light in a dark room)
Demagnetization (attenuation or transmission method)
