Project Description
When defect sizing accuracy matters, TOFD is a strong choice. VAIC’s TOFD inspection provides highly reliable flaw detection and sizing—helping clients make confident “accept / repair / monitor” decisions based on measurable reality.
This is the service you choose when you want engineering-grade confidence, supported by certified specialists and strong reporting discipline under strict QHSE execution.
Inspection technique
TOFD is an ultrasonic method that detects defects by capturing diffracted sound waves from flaw tips. This approach provides strong sizing capability and stable detection, particularly for weld inspection and critical components.
VAIC applies TOFD using advanced ultrasonic acquisition systems and professional scanning tools to ensure repeatable coverage and high-quality data suitable for technical review and long-term monitoring.
Applications
TOFD is ideal for:
Critical weld inspections requiring accurate sizing
Pressure equipment welds and high-integrity joints
Pipelines and structural welds where reliability is essential
Shutdown planning where sizing supports repair prioritization
Verification after repair to confirm integrity restoration
Projects requiring scan-based documentation
