東亜非破壊検査 List of Products and Services

"Ultrasonic testing" utilizes the property of ultrasonic waves traveling straight through metals and reflecting at the boundaries of different objects. Echoes reflected from flaws are received, and their position and size are measured. The angled testing method involves introducing ultrasonic waves at an angle to the testing surface and is used for inspecting welds and similar areas. The vertical testing method involves introducing ultrasonic waves perpendicularly to the testing surface and is widely used for inspecting plates, bars, forged steel products, and cast steel products. [Features] - High detection capability for surface flaws - Ability to ascertain the depth, direction, and position information of flaws - Capable of inspecting austenitic stainless steel welds *For more details, please refer to the PDF document or feel free to contact us.

• Flaw detection testing

The guided waves generated from the sensor propagate throughout the entire thickness of the plate (red wave in the figure below), and a portion of the guided waves is reflected at areas where the cross-sectional shape changes (such as corrosion and welds). By analyzing these reflected guided waves, we determine the presence or absence of defects.

• Other measurement, recording and measuring instruments

This technology utilizes the principle of eddy currents based on magnetism. By using direct current magnetization (DC-Magnetization), it enhances the permeability of the test specimen and allows for inspection without being affected by corrosion, paint, rubber, or plastic layers.
