While TOFD is a very powerful and efficient technique, it suffers from limited coverage resulting from two dead inspection zones: one dead zone is near the surface, the other is at the backwall.
OmniScan UT allows inspections simultaneously combining TOFD with conventional pulse echo. Pulse echo complements TOFD and covers the dead zones.

• TOFD inspection
• 45º pulse-echo for weld cap inspection on either sides of the weld
• 60º pulse-echo for weld root inspection on either sides of the weld
