Time-of-Flight Diffraction Inspection

Professional TOFD inspection services for Houston, Texas. Connect with certified NDT inspectors specializing in time-of-flight diffraction for Oil & Gas, Petrochemical, Aerospace, Power Generation industries.

Overview

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.

In Houston, Time-of-Flight Diffraction is essential for maintaining safety and reliability across critical industries including Oil & Gas, Petrochemical, Aerospace, Power Generation. Our certified NDT inspectors have extensive experience with Time-of-Flight Diffraction applications specific to Houston's unique industrial landscape and regulatory environment.

TOFD Principles & Process

How Time-of-Flight Diffraction Works

1
Two transducers in pitch-catch configuration
2
Diffracted signals from crack tips measured
3
Time-of-flight determines defect position and size
4
Less operator-dependent than conventional UT
