Internal flaws
Detects volumetric and planar flaws inside the weld, such as lack of fusion, cracks and inclusions, which surface methods cannot see.
Ultrasonic Testing (UT)
Manual ultrasonic testing of welds by operators certified to ISO 9712 Level 2 and Level 3, with evaluation and reporting.
Ultrasonic testing (UT)
Looking inside the weld with sound
Manual ultrasonic testing sends high-frequency sound waves into the material through a handheld probe. Reflections from internal discontinuities appear on the instrument screen, where a qualified operator locates, sizes and evaluates them.

- Evaluation against the acceptance criteria of the project
- Reporting and documentation
Why UT
What ultrasonic testing is good at
Portable and flexible
Portable equipment, access from one side only and no radiation hazard, so work around the inspection can continue.
Standardised
Ultrasonic testing of welds is described in standards such as ISO 17640, with acceptance levels defined by the applicable code.
Advanced ultrasonic methods
When manual UT is not enough
Phased array (PAUT)
Electronically steered beams and recorded images of the weld.
