PAUT Inspection
The NovaScan is designed for advanced phased-array ultrasonic inspection, where multiple ultrasonic elements are electronically controlled to steer and focus the ultrasonic beam.
This enables inspectors to perform:
Sectorial scans
Linear scans
Depth-focused inspection
Weld inspection
Internal flaw detection
Complex component inspection
FMC-TFM Imaging
One of the major advantages of the NovaScan platform is its support for FMC-TFM.
Full Matrix Capture collects ultrasonic data from multiple transmit/receive combinations, while Total Focusing Method processing creates highly focused images across the selected inspection region.
This can help inspectors visualize and characterize small or complex indications more effectively.
The NovaScan platform is documented as supporting TFM imaging, with some versions offering advanced 3D and multi-group capabilities.
TOFD Inspection
The NovaScan also supports Time of Flight Diffraction (TOFD) on configurations that include the conventional UT/TOFD module.
TOFD can be used alongside PAUT to improve flaw detection and sizing during weld inspection.
Applications
The Doppler NovaScan is suitable for:
Weld inspection
Pipeline inspection
Pressure vessel inspection
Corrosion detection
Thickness measurement
Material flaw detection
Oil and gas inspection
Aerospace NDT
Power-generation equipment
Railway inspection
Automotive manufacturing
Heavy machinery
Steel structures
Industrial manufacturing
Quality control
Research and engineering
Weld Inspection
The NovaScan is particularly useful for advanced weld inspection.
Potential indications include:
Lack of fusion
Lack of penetration
Cracks
Porosity
Slag/inclusions
Weld discontinuities
Internal material defects
Using PAUT, TFM and TOFD together can provide complementary information for detection and characterization.
What is the Doppler NovaScan used for?
It is used for phased-array ultrasonic testing, weld inspection, flaw detection, corrosion inspection, thickness measurement and advanced NDT.
Does NovaScan support TFM?
Yes. NovaScan is designed with FMC-TFM capability, although the exact TFM functions depend on the specific NovaScan generation and configuration.
Does it support TOFD?
Yes. NovaScan configurations include TOFD functionality through the conventional UT module.
Is NovaScan portable?
Yes. The NovaScan family is designed for portable/on-site ultrasonic inspection. Doppler specifically describes the NovaScan L3 as a lightweight portable system for on-site inspection.
What PA configurations are available?
This depends on the version. NovaScan V1 includes configurations such as 32/128PR and 16/128PR, while newer versions offer higher channel configurations.
