HistoricalConstraints for FMC/TFMHistoricalConstraintso Too Slow!o The volume of data (i.e. A-Scans) generated by FMC/TFM ismuch larger than PAUT (n vs. n²) greater processing time slower inspection speedso Too Much Data!o The volume of data (i.e. A-Scans) generated by FMC/TFM ismuch larger (n vs. n²) much larger file sizeo Lack of Sensitivity/Penetrationo With a single element transmitting, sensitivity andpenetration may be reducedNDT in Canada 2019 June 18-20 Edmonton, Alberta

Benefits of PWI (PWI/TFM) PWI acquisition with TFM imageprocessing PWI/TFMRepresents an optimization of both FMCdata set acquisition and TFM imagepost-processing5x-100x faster than traditionalFMC/TFMProvides greater sensitivityVery good penetration/SNR forattenuative materials (Ti, Inconel, etc.)Smaller file sizesGenerally, an “up-correlation” ininspection frequency; e.g. austeniticwelds inspected with 5MHzReduced technique development timeNDT in Canada 2019 June 18-20 Edmonton, Alberta
PWI (PWI/TFM) Explained PWI/TFM utilizes a larger transmitting aperture thanFMC/TFM, but with the proper algorithmic imageprocessing, the data set can still be used to create a TFMimageNDT in Canada 2019 June 18-20 Edmonton, Alberta
PWI (PWI/TFM) Explained As seen in the image below, several elements aretransmitting at once, but the imagereconstruction still considers each elementaltransmit/receive pair, as in “standard” FMC/TFMNDT in Canada 2019 June 18-20 Edmonton, Alberta

Conclusion PWI/TFM offers: Faster acquisition speeds TPAC can offer 12”/s Superior resolution of TFM imaging Better characterization and sizing Higher frequency/higher resolution inspection of attenuativematerials compared to PAUT Reduced technique development time Being focused “everywhere” reduces the need fordetermining focal laws/using multiple groups TPAC can offer inspection with multiple wave modes in oneacquisition Greater (full) coverage with one line scan (each side)NDT in Canada 2019 June 18-20 Edmonton, Alberta

Historical ConstraintsHistorical Constraints for FMC/TFM o Too Slow! o The volume of data (i.e. A-Scans) generated by FMC/TFM is much larger than PAUT (n vs. n²) greater processing time slower inspection speeds o Too Much Data! o The volume of data (i.e. A-Scans) generated by FMC/TFM is much larger (n vs. n²) much larger file size
