Solution
Blue Star addressed the client’s challenges with a tailored solution combining advanced ultrasonic techniques:
- Time-of-Flight Diffraction (TOFD): This technique provided complete weld volume coverage, accurately detecting volumetric flaws such as side-drilled holes. The diffraction-based approach ensured precise results even with high attenuation.
- Phased Array Ultrasonics: This method focused on inspecting the root area of the weld. By steering ultrasonic beams at varying angles, it effectively detected critical defects like notches with high precision, especially in challenging geometries.
The integration of TOFD and Phased Array provided comprehensive coverage and accurate detection of flaws, overcoming the challenges posed by titanium’s grain structure and attenuation. This combination ensured compliance with stringent aerospace standards.
