Time of Flight Diffraction (TOFD)

Diffracted wave physics for rapid sub-millimeter crack sizing accuracy.

Time of Flight Diffraction (TOFD)

Technical Overview

Time of Flight Diffraction (TOFD) relies on the diffracted ultrasound waves originating from flaw tips rather than reflected amplitude signals. This makes TOFD exceptionally accurate for height sizing of cracks regardless of flaw orientation or surface tilt.

Code Compliance & Standards:

ASME Section V Article 4 BS EN ISO 10863 ASTM E2373

Key Advantages & Capabilities

Sub-millimeter crack height measurement accuracy
Fast linear scanning speed covering the entire weld volume in a single pass
Unaffected by weld mismatch or surface roughness
Combines seamlessly with PAUT for comprehensive ASME compliant inspections
