For more than 20 years, Raynar has been developing and supplying NDT equipment to industries based on R&D and on-site practice in the field of NDT. In particular, Raynar has a unique technology called MRT(Magnetic Resonance Testing). Principles of MRT is when a certain frequency is applied to an electron rapidly rotating around the nucleus of an atom, the electron reacts and detect the degree of change outside of its normal rotation cycle and detects each defect.
MRT inspection technology is applied to pipe hydrogen embrittlement inspection, cracks, hardness, thickness, structural defects, health monitoring, sintering powder metal crack detection.

MRT is an advanced technology from ECT(Eddy Current Testing). This is the principle of ECT that uses a coil to generate a magnetic field. MRT is electromagnetic wave technology. MRT detects naturally occurring defects, welding defects, pit, line on the inner and outer surfaces of components regardless of size during processing.

Raynar MRT can monitor the welding condition of aluminum terminals welded to copper plates. MRT Welding Inspection Solutions Distinguish between normal and bad welding of aluminum and copper plates. On the surface, eddy currents are generated at high frequencies and gradually lower frequencies are applied to monitor the condition of the junction to determine the bond strength.

MRT identifies defects on the atomic level applying a magnetic field to a metal, which creates an electronic resonance phenomenon, and the reflected magnetic field is measured to detect defects according to an algorithm that determines the degree of deviations from the norm. MRT generally uses 8 frequency channels to scan 8 different depth level from object surface. And the number of channels can be increased depending on how detailed through thickness information is needed. On how MRT recognizes defects, MRT generally needs a reference point of a non-defective sample, and it will read the atomic structure of the reference point, and when the sensor picks up anything that is different in atomic structure from that of the reference point, it sends the signal back to the sensor.

• Non-destructive real-time automatic inspection for all metals.
• Detection of cracks, voids, fine defects, surface roughness, excessive stress, and dimensional variations.
• AI-based magnetic resonance detection for internal flaws.
• Global patented non-contact sensing system.
• Detection of internal, surface, and material defects in welding, soldering, and heat treatment.
• Storage and statistical management of inspection data.
• Remote unmanned tuning and management system operation.

MRT is currently used as inspection equipment used by steel companies, automotive engine blocks, and thread inspection equipment such as copper and aluminum. Raynar has developed and supplied various pipe inspection equipment such as stainless steel, and they have developed and supplied various pipe inspection equipment in Japan, China, Germany, Taiwan, France, etc. Also, their products are delivered to steel powerhouses such as India. In addition, Raynar holds more than 20 patents. Raynar says that they will do their best to help their customers achieve their dreams of zero defects by developing equipment that applies sensing technology to find defects in various parts and materials by nurturing excellent talents.
