Ultrasonic technology has been used for testing ERW welded pipe at various points in the manufacturing process for many years. 

Friction stir weld (FSW) inspections in aerospace manufacturing are challenging for ultrasound technicians not necessarily because they require specialized computations or complex techniques but because scanning with conventional probe setups can be so time consuming.

It’s been nine years since a heat exchanger burst at an oil refinery in Anacortes, WA, fatally injuring seven workers and bringing renewed attention to the risks of high-temperature hydrogen attack (HTHA).

Fast and reliable, PAUT technique has dramatically improved the probability of detection of defects inside a weld and became over the years a code compliant replacement solution to the radiographic testing.
