[Equipment Introduction] Etching before Penetrant Testing

[Equipment Introduction] Etching before Penetrant Testing

Etch the sample surface to expose scratches and voids! This allows for more accurate penetrant testing.

Our company has equipment that meets the etching standards for aircraft engine parts. By etching the sample surface to expose scratches and voids, it is possible to conduct more accurate penetrant testing. The target samples are aluminum alloys and magnesium alloys. Penetrant testing utilizes the principle that fluorescent liquid reacts to ultraviolet light, causing fine scratches and voids on the sample surface to glow in fluorescent colors. Cracks less than 0.01mm wide and dents less than φ0.01mm can also be detected. 【Specifications】 ■ Target samples: Aluminum alloys / Magnesium alloys ■ Maximum sample size: 1000x600x600mm ■ Alkaline cleaning solution: Super Bee 300LF ■ Etching solution: Deoxidizer 6 *For more details, please refer to the PDF document or feel free to contact us.

Penetrant Testing

Penetrant Testing

The operating temperature is from room temperature to 200°C! It has excellent ability to detect cracks and circular defects!

"Penetrant Testing" is a method that targets surface-opening defects that occur on material surfaces. It involves applying a penetrant liquid, which is drawn out to the surface through capillary action, and the resulting indications are perceived through visual inspection. Since liquid penetrants are used, it is possible to detect defects in the details of complex-shaped test specimens. It is highly effective in detecting cracks and circular defects in various orientations. This method can be applied to all materials except for hygroscopic materials, regardless of whether they are magnetic, non-magnetic, metallic, or non-metallic. 【Features】 - Targets surface-opening defects that occur on material surfaces - Uses liquid penetrants - Excellent ability to detect cracks and circular defects - Accommodates defects in various orientations - Operating temperature: Room temperature to 200°C *For more details, please refer to the PDF document or feel free to contact us.

Ultrasonic Testing "Oblique Angle Testing Method"

Ultrasonic Testing "Oblique Angle Testing Method"

By using direct method and single reflection method from one side of the test specimen, a wide range of inspections is possible!

The "Oblique Angle Ultrasonic Testing Method" is one of the ultrasonic testing methods used to examine the presence, location, size, shape, and distribution of defects in materials and products without causing any damage. This method involves transmitting and receiving ultrasonic waves at an angle to the testing surface. It allows for inspection in areas where vertical testing cannot be applied, such as welds. Additionally, inspections can be conducted using different angles, such as 45° or 70°, depending on the shape and thickness of the weld. The applicable temperature range is approximately room temperature to 150°C, and the materials targeted include carbon steel and stainless steel. **Features** - Investigates the presence, location, and size of defects without damaging materials or products. - Transmits and receives ultrasonic waves at an angle to the testing surface. - Enables inspection in areas where vertical testing is not applicable, such as welds. - Allows for inspections using different angles, such as 45° or 70°, based on the shape and thickness of the weld. - Applicable temperature: approximately room temperature to 150°C (for hot air furnaces, etc.). *For more details, please refer to the PDF document or feel free to contact us.*

Jasco Magnetic Particle Inspection

Jasco Magnetic Particle Inspection

This is an inspection technique used for welding joint inspections of large tanks (new installations, open inspections) and various small parts inspections.

If there are defects on the surface of the test specimen and just below the surface, the passage of magnetic flux is hindered, leaking into the space and generating magnetic poles on both sides of the defect, creating a magnetic field.
