There are no commercially available Non Destructive Testing (NDT) systems that can examine the entire volume of diffusion bonded joints/welds to the required industrial standard(s) in terms of reliability, repeatability and high sensitivity of defect detection capability. In order to develop rapid, reliable and high defect sensitivity ultrasonic NDT systems that will economically examine the entire volume of the diffusion bond joint, the following development activities must be undertaken:
- Manufacture of precision test samples containing manufacturing and in-service defect.
- Modelling of ultrasonic beam characteristics in the specified dissimilar metal/material combinations
- Phased Array Transducer development to meet technical/functional specifications
- Data Imaging Software development to reconstruct and clearly display acquired test data
- Full Matrix Capture (FMC) technique to image all points of the beam in focus and enhance SNR and defect detection
- Automated Defect Recognition (ADR) Software to aid defect interpretation
- Reference Library of representative defects to aid manual defect interpretation and confirm ADR
