TOFD uses diffracted ultrasonic signals from flaw tips for precise defect sizing and is often paired with PAUT.
Time-of-Flight Diffraction (TOFD) is an advanced ultrasonic technique that uses the time of flight of diffracted signals from the tips of defects to accurately determine flaw height and through-wall extent. TOFD is widely used for critical weld inspection and is often combined with PAUT to provide comprehensive inspection coverage.
Component Size & Complexity
Larger or more complex parts require more time and expertise
Access Requirements
Difficult-to-reach areas increase inspection time and cost
Acceptance Criteria
Stricter standards (aerospace vs. general manufacturing) require more scrutiny
Equipment Requirements
Advanced equipment like PAUT or TOFD costs more than basic methods
Certification Requirements
Higher-level certifications command premium rates
Travel Distance
Remote locations in Houston may add travel and logistics costs
Volume of Work
Larger inspection projects often have reduced per-unit costs
Timeline Urgency
Rush inspections typically have premium pricing
