Professional TOFD inspection services for San Francisco, California. Connect with certified NDT inspectors specializing in time-of-flight diffraction for Construction, Manufacturing, Power Generation, Marine 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.
