TOFD (Time-of-Flight Diffraction)

Time-of-Flight Diffraction (TOFD) is an advanced ultrasonic testing technique that utilizes diffracted signals generated by flaws to detect and characterize defects in welded joints and other structures. It offers high sensitivity and accuracy, making it a preferred method for inspecting critical components in various industries.

Applications of Time-of-Flight Diffraction :

  • Weld Inspection
  • Corrosion Monitoring
  • Pipeline Inspection.

Advantages of Time-of-Flight Diffraction :

  • High Sensitivity: TOFD offers high sensitivity to small defects, providing accurate and reliable detection and sizing of flaws, even in challenging materials and geometries.
  • Full Coverage: It provides full coverage of the inspected area, detecting flaws throughout the thickness of the material and along the entire length of the weld, ensuring comprehensive inspection results.
  • Accuracy: TOFD offers high accuracy in defect sizing, allowing for precise characterization of flaws and reliable assessment of their impact on the structural integrity of components.
  • Real-Time Imaging: It provides real-time imaging of the inspected area, allowing for immediate analysis and decision-making regarding the disposition of components or structures.
  • Efficiency: TOFD can perform inspections quickly and efficiently, reducing inspection times and minimizing downtime in production or maintenance operations.
