#ndt When passengers board a train, most don’t consider the amount of work that goes into inspecting key components to help ensure a safe ride. An essential tool in this inspection process is a phased array flaw detector that sends high-frequency sound waves from a probe into a component to look for defects. If the sound waves encounter a flaw, some of the sound energy gets reflected back to the probe. The flaw detector reads these signals and displays information that a trained inspector can use to assess the c
