| 【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. | 【Application】 <Inspection Targets> ■ Welded joints of piping, structures, etc. Example: Detection of inherent defects in welded joints, detection of stress corrosion cracking (SCC) on the inner surfaces of containers and piping. <Target Materials> ■ Carbon steel, stainless steel, etc. *For more details, please refer to the PDF document or feel free to contact us. | ||
Penetrant Testing
Other |
【Construction Example (Solvent Removable Dye Penetrant Testing)】 ■ Remove dirt from the surface and inside of the cracks (Pre-treatment) ↓ ■ Apply penetrant to the material surface (Penetration Treatment) ↓ ■ After a certain period of penetration, remove with a dry cloth (Removal Treatment) ↓ ■ Remove the penetrant with a cloth soaked in cleaning solution (Removal Treatment) ↓ ■ Apply developer (Development Treatment), observe after a certain period of development ↓ ■ Penetrant indication pattern (cracks) drawn out by the developer *For more details, please refer to the PDF document or feel free to contact us. | 【Usage】 ■All materials except those with moisture-absorbing properties *For more details, please refer to the PDF document or feel free to contact us. | |
| 【Other Features】 ■ Since it utilizes the reflection method, inspection can be performed from only one side of the test specimen (usually, inspection and judgment are made from both sides). ■ Normally, only the bottom echo appears in the sound area, but if there is a defect, it appears as a defect echo before the bottom echo. *For more details, please refer to the PDF document or feel free to contact us. | 【Purpose】 <Inspection Targets> ■ Welded joints of structures, cast and forged steel products, bolts, pins, etc. Example: Detection of internal defects in axles and welded joints of monorails, detection of defects in bolts and pins. <Target Materials> ■ Carbon steel, stainless steel, etc. *For more details, please refer to the PDF materials or feel free to contact us. | ||
