Magnetic particle testing

Magnetic particle testing

Magnetic powder adheres to the defect, causing the defect to expand! Introducing an inspection method applicable to ferromagnetic materials.

Magnetic Particle Testing is a suitable inspection method for detecting flaws near the surface of ferromagnetic materials. When a test specimen with cracks or other flaws in the surface or just below the surface is magnetized, magnetic flux leaks from the flaws, creating magnetic poles. When magnetic particles are sprinkled on the surface of the test specimen, they adhere to the flaw, highlighting it and making detection easier. 【Features】 ■ Applicable only to ferromagnetic materials ■ Effective for surface flaws ■ An effective inspection method for crack-like flaws ■ In locations where outdoor or dark conditions are not possible, color magnetic particles (white, black, etc.) that do not require black light are used. *For more details, please refer to the PDF document or feel free to contact us.

Ultrasonic testing

Ultrasonic testing

It is possible to convert the time required for reflection into thickness and measure the thickness of materials that cannot be measured with calipers, etc.

"Ultrasonic flaw detection" involves placing a sensor called a probe against the surface of materials such as metal and transmitting ultrasonic waves. Ultrasonic waves are reflected at the boundary between different materials, such as metal and air. By utilizing this property, the position and size of flaws within the test specimen can be measured through the reflected echoes from these flaws. There are two main methods of flaw detection: the angled flaw detection method, which involves transmitting ultrasonic waves at an angle from the test surface and is used for detecting welds, and the vertical flaw detection method, which involves transmitting waves perpendicularly from the test surface and is used for detecting flaws in shafts and plates. [Features] - Measures the position and size of flaws from the reflected echoes within the test specimen. - The flaw detection methods are broadly classified into two types. - Can also measure the thickness of materials that cannot be measured with calipers. *For more details, please refer to the PDF document or feel free to contact us.*

Penetrant testing

Penetrant testing

Even narrow scratches or small diameter defects that are usually not visible to the naked eye can be confirmed visually!

"Penetrant testing" is a method for detecting cracks and other openings on the surface of test specimens through the capillary action of liquids. The penetrant is allowed to seep into the surface of the test specimen, and after removing the excess penetrant, a developer draws the penetrant that has seeped into the cracks back to the surface, allowing for the detection of the flaws. Since a magnified pattern of the actual flaw dimensions is formed, even narrow or small-diameter flaws that are normally invisible to the naked eye can be confirmed visually. 【Features】 ■ Detects cracks and other openings on the surface of the test specimen ■ The developer draws the penetrant that has seeped into the cracks back to the surface, allowing for flaw detection ■ A magnified pattern of the actual flaw dimensions is formed ■ Even narrow or small-diameter flaws that are normally invisible can be confirmed visually *For more details, please refer to the PDF document or feel free to contact us.

Magnetic particle testing

Magnetic particle testing

It is possible to check for invisible cracks! Suitable for detecting cracks that exist near the surface.

"Magnetic particle testing" can only be applied to ferromagnetic materials that are attracted to magnets. When using the equipment to magnetize a ferromagnetic material (test specimen), a flow of magnetism called magnetic flux is generated within it. If there are cracks or other defects on the surface or near-surface of the test specimen, the magnetic flux will leak into the surface space due to the defects, forming small magnets. When very fine iron powder (magnetic powder) that is colored is sprinkled onto that area, the magnetic powder adheres to the defect, and the adhered magnetic powder becomes a magnet, allowing the magnetic powders to stack and form patterns, which is used to detect the defects. 【Features】 ■ Can only be applied to ferromagnetic materials that are attracted to magnets ■ Utilizes the adhesion of magnetic powder to defect areas, where the adhered magnetic powder becomes magnets, allowing the powders to stack and form patterns to detect defects ■ The aggregation of magnetic powder creates patterns that are enlarged compared to the actual defects ■ Allows for the detection of narrow, invisible defects *For more details, please refer to the PDF document or feel free to contact us.
