Benefits

The main benefits of the BondTest include

  1. A reliable manufacturing and in-service (where access permits) ultrasonic testing method that is rapid, collects, processes and, if needed, displays all of the ultrasonic data to a high defect detection (sensitivity) capability with a high SNR (see benefit 2 below).
  2. Accurate sizing and characterisation of critical defects with a target amplitude Signal to Noise Ratio of 12dB with a minimum of at least 6dB. All detected defects could be evaluated allowing an Engineering Critical Assessment (ECA) to predict the future potential failure likelihood.
  3. The ability to use FMC to produce an in-focus image at any point in the diagnostic area, thus increasing the image resolution, defect detection and sizing capability when compared to conventional PAUT.
  4. Where appropriate, the ability to apply ADR software to speed up the data interpretation process, standardise and ensure accuracy and repeatability of defect assessment according to the defect acceptance/rejection criteria.
  5. Increased confidence in the integrity of dissimilar metal diffusion joints because they can be properly tested.
  6. The ability to examine dissimilar metal/material diffusion bonded joints to demonstrate a high level of joint integrity will enable the joining process to find further applications of a demanding nature without the need to destructively test, on a statistical basis, a specified number of those manufactured. New applications for diffusion bonding in the existing aerospace market, and applications in new markets (e.g. process plant) are likely to follow.
  7. Access to a Reference Library of representative dissimilar metal diffusion bond defect images in order to aid consistency of defect evaluation as manual interpretation can prove to be inconsistent.
