Wedge ultrasonic probe 5L32-A31

acousticfor weldingangle beam

Overview
A31 and A32 Weld Series phased-array probes are designed to simplify and standardize weld inspections. They provide improved signal-to-noise performance and a wedge concept that enhances coupling to the inspected part; probes are acoustically matched to Rexolite.

Advantages

• Design optimized for weld inspection with angle-beam operation.
• Improved signal-to-noise ratio for clearer defect detection.
• Wide coverage of weld thicknesses from 3 mm to 60 mm.
• New wedge concept for enhanced coupling; available for shear or longitudinal waves.
• Available in multiple frequencies, pitches and 32 or 64 element options.

Typical Applications
A31 and A32 Probes

• Manual or automated phased-array inspection of welds 3–60 mm thick using angle beams.
• Inspections on pipes, plates and weld seams.
• Configuration selectable for shear or longitudinal wave testing according to application requirements.
