【Newspaper】 2019/5/1 Our representative Inoue comment was described in “NIKKAN KOGYO SHINBUN(Newspaper）”.
The article about GNES Corporation is published at the corner of “Strength of our company from Kyoto” on “Creative Kyoto M&T (Mar/2018)”.
Our Corporate website has been renewed.
NDT(Non Destructive Testing) is one of the inspection technology, detecting invisible defects or quality situation, such as cracks and voids, which cannot be checked visually for materials, parts or finished products, without damaging the objects physically. It is commonly used in the field of research and development.
UT(Ultrasonic Testing) is one of Non Destructive Testing, which is specialized in detecting defects of metals or composite materials etc. by using ultrasonic waves. There are two techniques, the pulse echo technique, and the through transmission technique.
-“Pulse echo technique” can detect the presence, size, shape and depth of the defects, by inspecting strength of reflection wave and propagation speed of the ultrasonic pulse through inside of material.
-“Transmission technique” is a way which receive a pulse generating from transmitting probe by using receiving probe. We can know the size and shape of the defects by detecting strength of transmitted wave, because the defect decrease ultrasonic pulse power through inside of material.
We use 0.1-100MHz range of ultrasonic by detecting defect, and mostly uses 1-10MHz range of ultrasonic for metal materials.
Air-coupled Ultrasonic Testing is one of the method which is a flaw detection inspection without using couplant. We normally use couplant such as water or oil for ultrasonic testing.
We can provide Air-coupled ultrasonic testing system, so we can detect the defects of the materials that can not be attached by water and oil, without using couplant.
We provides a special ultrasonic testing solution for the thick materials like building material and woods with high sensitivity probes.
