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.*

basic information
【Other Features】 - Unlike vertical flaw detection, echoes are not received in the sound area, and echoes appear only when there is a flaw. - By using direct transmission and single reflection methods from one side of the test specimen, a wide range of inspections can be performed. - Generally, flaw detection is performed using shear waves (SV waves), but by propagating longitudinal waves at an angle or using waves called SH waves, the scope of flaw detection can be expanded. *For more details, please refer to the PDF document or feel free to contact us.
