Advanced UT (PAUT) - Rail

The beam from a PA probe can be focused and swept

electronically without moving. With ultrasonic PA

linear scan, the probe is placed on the tread surface

during the scanning process, and the flaw detection

can be completed without moving the probe.

With the function of flexible control

scanning acoustic beam angle, inspector

can angle the wave beam in multiple

directions to cover more of the testing

radius and spotting defects without

replacing the probes.

PA multi-angle scanning can avoid the

leak case, compared to conventional

UT which is nearly impossible to

diverge from a fixed beam position.

PA strong acoustic beam energy is

helpful for testing the defects which

reflection signal is weak, and defects

in rail waist with deep position, leading

to high detection sensitivity.

The special software is designed

according to the inspection process of

rail welds, and a number of inspection

methods can be selected for different

rail parts.
