Phased Array Ultrasonic Testing (PAUT) is not a new concept, the technology has been available for many years and is widely used in the medical field. Portable equipment became available in the late 1990s and is steadily replacing radiography as THE primary inspection method.
This technique is used for the detection of manufacturing defects in new construction welds, and for the detection of in-service defects.
The technique may also be used for corrosion mapping and is an excellent tool for inspecting complex geometry’s such as castings and wrought products.
PAUT is a rapid scanning tool that gives accurate defect length, depth and through wall extent.
This technique is: Highly portable; Safe; Fast; Accurate.
