Abstract:

From 1996 to 2016, Transportation Technology Center, Inc. (TTCI) analyzed historical probability of detection (POD) data for the fusion welded tank car butt welds (BW) and fillet welds (FW) inspection using Code of Federal Regulation (CFR)-approved nondestructive evaluation (NDE) methods. The research team analyzed a total of 197 POD datasets (i.e., for both the BW and FW) using 3 different statistical approaches: traditional statistics, logistic regression based maximum likelihood estimate approach, and the National Aeronautics and Space Administration (NASA) design of experiment POD (DOEPOD). The Federal Railroad Administration (FRA) sponsored this work and the railroad tank car industry participated by evaluating the capabilities of currently CFR-approved NDE methods on the railroad tank cars welds.
