NDT208 — Full Matrix Capture (FMC/TFM)
3 , 3 lecture periods 0 lab periods Provides a basic knowledge on full matrix capture (FMC) consistent with other methods, and to acknowledge FMC and total focusing method (TFM) as unique enough to warrant an additional body of knowledge and qualification requirement. Demonstrate proficient knowledge and application of FMC/TFM. Demonstrate proficient knowledge of how to set up and calibrate NDT equipment. Demonstrate proficient knowledge and basic understanding of advanced phased array.
