Phased Array Ultrasonic Testing in Baton Rouge
Multi-element ultrasonic imaging with electronic beam steering for advanced weld and corrosion mapping.
Mississippi-river-corridor turnarounds cluster from October to February — keeping every Level II's recert current ahead of that window is a six-month planning exercise.
How Phased Array Ultrasonic Testing works
A 16- to 128-element transducer is fired with controlled time delays to steer and focus the ultrasonic beam electronically. Sectorial (S-scan) and linear (L-scan) imaging produce real-time cross-sections; encoded scanning produces permanent digital records.
PAUT in Baton Rouge
