PAUT & UT Probes and Wedges
Ultrasonic probe and wedge families support phased array, TFM and TOFD inspections for welds, corrosion, complex geometries and high-temperature components.

Product overview
Eddyfi Technologies' Phased Array Probes and Wedges encompass linear, matrix, dual-matrix, flexible, immersion and contact-membrane designs, alongside TOFD transducers. The range uses advanced piezocomposite technology for applications including flaw detection, thickness gauging and material research, with customizable configurations and wedges for specific inspection requirements.
Linear phased array probes provide electronic control for inspections of welds, pipes, plates and other components. Matrix arrays support full matrix capture, while TFM processing focuses the captured data at all points within the inspection area to produce detailed images. Dual-matrix probes use transmit-receive configurations to improve sensitivity and signal-to-noise ratio in coarse-grained materials, corrosion-resistant alloys and dissimilar metal welds. Separate broadband, highly damped TOFD probes are intended for determining crack dimensions in metallic welds.
Application-specific designs address restricted access and difficult surfaces: small-footprint and low-profile probes suit confined spaces, flexible arrays follow curved metals and composites, and immersion arrays enable non-contact inspection of intricate geometries. Contact-membrane probes provide coupling on threaded bolts and rough surfaces, while corrosion arrays cover large surfaces more efficiently than single-element inspections.
High-temperature linear probes offer separate mid-temperature and high-temperature wedge options, with published operating bands extending to 200°C. The high-temperature dual-linear corrosion array is designed for inspections up to 200°C (395°F). Custom engineering also covers specialized arrays for tube and bar testing, aerospace forgings and carbon-fiber-reinforced polymer corners.
Key capabilities
Configurable linear arrays
General-purpose probes offer variations in frequency, element count and pitch for different inspection tasks.
Restricted-access designs
ABFP small-footprint probes and low-profile arrays address confined spaces and small-diameter pipe inspections.
TOFD transducers
Highly damped broadband probes feature quick-swap screw-in wedge attachments for metallic weld crack sizing.
Large-area corrosion scanning
Corrosion arrays target corrosion and erosion on extensive surfaces while reducing inspection time compared with single-element inspections.
Flexible surface conformity
FlexArray probes adapt to various radii on curved metals and composites.
Replaceable contact membrane
Contact-membrane arrays support coupling on rough surfaces and threaded bolts, with customizable side-mounted or top-mounted cables.
FMC and TFM imaging
Matrix arrays support full matrix capture, and TFM processing focuses inspection data throughout the inspection area.
Dual-matrix beam skewing
Transmit-receive configurations and beam-skewing capability support inspections of challenging materials and dissimilar metal welds.
High-temperature configurations
Dedicated linear and dual-linear designs address elevated-temperature weld, tube and corrosion inspections.
Custom probe engineering
In-house design, machining, ceramic fabrication and application engineering support specialized inspection geometries.
