The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

NDT Mart & Rental Co., Ltd. began selling its new electromagnetic ultrasonic thickness gauge, 'EMAT WIFI', on January 19, 2026. ◆ Electromagnetic Ultrasonic Thickness Gauge 'EMAT WIFI' The 'EMAT WIFI' is a thickness gauge that uses the electromagnetic ultrasonic (EMAT) method, which does not require a couplant (contact medium). Unlike conventional ultrasonic thickness gauges (UT), there is no need to apply a couplant; thickness measurements can be taken simply by placing the probe on the measurement target, making it ideal for beginners and screening in large-scale sites. It can measure materials with paint, scale, thick linings, and slight surface roughness, significantly reducing the hassle of pre-treatment. Additionally, it is equipped with WiFi communication capabilities, allowing for the confirmation and management of measurement data and waveforms in conjunction with smartphones and tablets. This facilitates smooth sharing of measurement results and data management on-site. It is optimal for measuring wall thickness and conducting corrosion inspections of plant equipment, piping, tanks, and steel structures. It contributes to the efficiency and reliability of thickness measurements in the field of non-destructive testing (NDT), such as maintenance inspections and equipment diagnostics.
