Product Overview
The BBND-WI is designed for ultrasonic inspection of welds in pipelines, pressure vessels, tanks, steel structures, bridges, rail components, and industrial equipment. It introduces ultrasound into the test material at a selected angle to detect cracks, lack of fusion, incomplete penetration, slag inclusions, and other discontinuities in the weld and heat-affected zone.
Multiple frequencies, inspection angles, element sizes, and wedge configurations are available for conventional welds, thick-wall components, small parts, restricted access areas, and selected elevated-temperature applications. Phased array configurations are available for electronic scanning and dynamic focusing.

- Aerospace structures and critical load-bearing components
Selection Parameters
Selection is based on the test material, weld type, wall thickness, joint geometry, inspection standard, required beam angle, frequency, scan coverage, wedge curvature, operating temperature, and instrument interface.
Compatible Equipment
- Conventional ultrasonic flaw detector or phased array instrument
- Probe cable
- Matching wedge
- Ultrasonic couplant
- Weld calibration block
- Manual or automated scanner
Operating Requirements
- Match the inspection angle and frequency to the weld geometry, material, and applicable inspection standard.
- Match the wedge contact surface to the component curvature and maintain stable coupling.
- Calibrate sound path, angle, sensitivity, and gain with an appropriate reference block before inspection.
- Follow the specified contact-time and cooling requirements for elevated-temperature configurations.
