Our company conducts MT (Magnetic Particle Testing). This method is applicable for detecting flaws that exist on the surface or near the surface of ferromagnetic materials (steel). Using the principle that iron particles are attracted to a magnet, the test object is magnetized with a magnet or similar device. The magnetic particles are attracted to the magnetic poles generated at the surface and near-surface flaws of the test object, allowing for the observation and detection of these flaws. 【Features】 ■ Utilizes the principle of iron particles being attracted to a magnet ■ Observes magnetic particles to detect flaws ■ Applicable for detecting flaws on the surface or near-surface of ferromagnetic materials *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts UT (Ultrasonic Testing). In ultrasonic testing, frequencies ranging from 500 kHz to 10 MHz are utilized. Compared to electromagnetic waves and light, the propagation speed of sound is significantly slower, and sound cannot propagate without a medium, so the propagation speed varies depending on the properties of that medium. For example, the speed of sound in air is about 340 m/s, in water it is about 1,530 m/s, and in iron it is about 5,000 m/s. In contrast, light and electromagnetic waves travel at 300,000 km/s (3×10^8 m/s). Additionally, sound tends to attenuate easily in gases, while it propagates efficiently in liquids and solids. Due to its slower propagation speed, ultrasound is convenient for measuring distances; specifically, it involves emitting ultrasonic waves and measuring the time taken for the reflected waves to return, allowing for distance measurement. Applications include ultrasonic thickness gauges (which measure the thickness of materials such as steel plates). *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts PT (penetrant testing). When a penetrant is applied to the surface of the test specimen, it penetrates into open flaws. The indication patterns of the penetrant that have adhered to the inside of the flaws allow us to detect surface-open flaws, welding defects, fatigue cracks, and more. It can be applied to almost all materials, excluding porous materials. 【Features】 ■ When a penetrant is applied to the surface of the test specimen, it penetrates into open flaws ■ Detects surface-open flaws, welding defects, fatigue cracks, and more ■ Applicable to almost all materials, excluding porous materials *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts RT (Radiographic Testing). What comes to mind when you hear "radioactivity"? Generally, many people associate it with what is commonly referred to as "X-rays." X-rays are a type of radiation used in medical applications, and both X-rays and gamma rays can easily penetrate materials, whether it be the human body or welded steel; they fundamentally pass through. However, not all materials are equally penetrable; some are easier to penetrate than others. Even when radiation is emitted under the same conditions to sensitize the film, there will be variations in shadow density on the film. It is through these variations in density that we assess the condition of the contents. *For more details, please refer to the PDF document or feel free to contact us.
