FMC/TFM Inspection of Welded Structures


Introduction

Total Focusing Method (TFM) / Full Matrix Capture (FMC) technology show potential to improve weld flaw sizing performance compared to phased array ultrasonic testing (PAUT). TFM is an imaging algorithm that operates on data acquired using FMC data acquisition. TFM/FMC refers to both the data acquisition and processing method used for advanced ultrasonic testing applications. TFM/FMC is a variation of Phased Array Ultrasonic Testing (PAUT and may improve flaw sizing at the expense of inspection speed.
