Details
As the ultrasonic phased array (PAUT) applications and the related equipment became more and more common in aerospace industry, both for large inspection systems in manufacturing as well as portable devices, the latest generation of equipment additionally offers the total focusing method, TFM, based on full matrix capture, FMC.
For an efficient inspection AIRBUS Operations makes use of these options and develops dedicated inspection procedures, both for manufacturing and In-Service applications.
In manufacturing one application for the TFM method is related to the inspection of Additive Manufactured Parts made by Direct Energy Deposition (DED). Due to its dedicated focussing on each pixel of the Region of Interest (ROI) the TFM method enables a significant improvement in detection and sizing of small irregularities in those metallic parts. Furthermore, the entire thickness of the inspection area can be covered without adapting the setup / focussing parameters which leads to an improved and accelerated inspection process.
An example for an In-Service application is the inspection of metallic T-shaped components. The target is to detect fatigue cracks in webs of various configurations in terms of thickness, bore hole diameter and depth, with only one inspection setup. In order to overcome the complexity of failure-prone procedures with many different equipment settings using conventional PAUT technology, the inspector can now inspect these different components and configurations with one equipment setup, thanks to focussing in each pixel of the ROI obtained by TFM reconstruction.
The presentation will give an overview of the TFM technique including relevant examples of its use on different AIRBUS applications.
