Cover More of the Weld and HAZ—Angle-Beam DLA Probe (A28)

• High-resolution 10 MHz dual 32 small-element arrays
• High beam-steering capability
• Increased probability of detection (POD) offered by a longer focal range due to its patented pivoting housing
• Series of wedges with roof angles offering passive focusing for depths from 4 mm to 95 mm (0.16 in. to 3.74 in.)       

Fast HTHA Scanning—Zero-Degree DLA Probes (REX1)

• 10 MHz dual 64-element arrays
• Beam width coverage up to 30 mm (1.18 in.)
• Adjustable stabilization and carbide wear protection system fits to the surfaces of pipes as small as 4 inches (101.6 mm) OD
• Integrated wedges covering thicknesses from 4 mm to 95 mm (0.16 in. to 3.74 in.)
• Provides clear C-scan images when used with an encoder or scanner        

Earlier HTHA Detection—TFM Probes Optimized for HTHA (A31/A32)       

• High frequencies with multiple smaller elements unleash the potential of TFM for HTHA detection     

Wedges for the A28 Probe

The angle beam wedge series is optimized for weld volume and heat-affected zone inspection. The wedge angle is set to generate L-waves at a 65-degree nominal incident angle in steel. They feature a roof angle calculated for each AOD diameter.

SA28 wedges are avaliable in two focus depths to cover a wide range of thicknesses:

• SA28-N65L-FD25: Optimized for part thicknesses ranging from 4 mm to 45 mm
• SA28-N65L-FD60: Optimized for part thicknesses ranging from 45 mm to 95 mm
