The Principle of TOFD Testing
TOFD is "Time-Of-Flight Diffraction", which is based on Huygens Diffraction Principle. It's a Nondestructive Testing method with ultra-high accuracy. TOFD testing is usually used for confirming the location, characteristics and evaluation of defects in the material. This method utilizes the symmetrical arrangement of two transmitting and receiving probes to capture diffraction signals from defect tips.
Advantages of YUSHI TOFD Probes
When YUSHI TOFD probes are connected with the quick-release type wedges, they will transmit the ultrasonic wave that will diffract at the lower tips or upper tips of the defects and the bottom of the material.The time difference between the transmitting and received signals will directly indicate the localization and characteristic of the cracks, inclusions or other flaws.
YUSHI TOFD probes' key advantages include:
- High Sensitivity and Hide Bandwidth: YUSHI TOFD probes adopt composite elements for higher accuracy and high bandwidth.
- Quick-release Type Wedges: YUSHI TOFD probes are connected with quick-release type wedges, which make the measurement more convenient.
- Excellent Signal-to-Noise Ratio:The probes are longitudinal wave probes with high damping characteristics. This can help to the ability for distinguishing the back echo from the noise.
- Efficient Weld Inspection: YUSHI TOFD probes with high accuracy can greatly increase the efficiency of weld inspection.
- Great Durability: Wedges feature wear-resistant pins, integrated water nozzles for coupling and side slots for debris management.
Q&A
1.Can YUSHI's TOFD probe be used with TOFD ultrasonic flaw detectors on the market?
At present, Israel's TOFD flaw detector cannot be matched.
2.How long does it usually take to ship?
If the model you ordered is in stock,it can be sent within two business days.
If the model you ordered is not in stock,it can be sent within three weeks.
International shipping usually will take 5-12 business days.
