Sonatest — X0AW-N55S-IHC Angle Beam Wedge (55° Shear Wave, AOD 16")
Precision UT Wedge for Steel Inspection Applications SKU: X0AW-002-16Overview
The Sonatest X0AW-N55S-IHC is a precision ultrasonic wedge designed for angle beam inspections on steel components. Configured to generate a 55° shear wave (SW), this wedge is optimized for detecting and evaluating weld defects such as cracks, lack of fusion, and inclusions.
With a cut angle of 39° and an extended Active Offset Distance (AOD) of 16 inches, this configuration is engineered for very large geometries and deep inspection zones, offering maximum beam reach and positioning flexibility. The zero delay line design (0 mm) allows direct ultrasonic transmission into the test material, improving signal strength and inspection efficiency.
Designed for compatibility with Sonatest ultrasonic systems, this wedge is ideal for large-scale inspection applications in industries such as oil & gas, fabrication, and power generation where extended coverage is required.
