Magnetic Particle Testing (MT) / Ultrasonic Testing 【Problem Solving】

Magnetic Particle Testing (MT) / Ultrasonic Testing 【Problem Solving】

Detection of fine surface cracks invisible to the naked eye. Enables quantitative assessment of damage and corrosion in steel materials!

Magnetic particle testing is an extremely precise surface inspection method that can detect fine surface cracks that are not visible to the naked eye. Phased array ultrasonic testing does not require any surface preparation, such as the removal of coatings or rust, and allows for data collection and evaluation to be done off-site. It also offers superior workability compared to conventional ultrasonic equipment. 【Customer's Challenge】 Significant damage was found on a steel bridge, and a non-destructive test that is not easily detectable by visual inspection was urgently needed. 【Solution】 We visited on the same day we were contacted and conducted inspections using magnetic particle testing and ultrasonic testing until the repair of the damage was completed. *For more details, please contact us or download the PDF to view.
